TOPLINE:

New Canadian guidelines for the management of high-risk drinking and alcohol use disorder (AUD) include 15 recommendations on screening, diagnosis, withdrawal management, and ongoing treatment including psychosocial interventions, drug therapies, and community-based programs.

METHODOLOGY:

  • The Canadian Research Initiative in Substance Misuse convened a 36-member committee of clinicians, researchers, people with personal experience of alcohol use, and Indigenous or Métis individuals to develop the guidelines, using the Appraisal of Guidelines for Research and Evaluation Instrument.
  • Risk assessment was based on Alcohol Use Disorders Identification Test-Consumption scores.
  • The definition of AUD was based on patients experiencing “clinically significant impairment or distress” from their alcohol use, with severity being mild, moderate, or severe.

TAKEAWAY:

  • All adult and youth patients at moderate or high risk for AUD should be screened annually for alcohol use, and those screening positive should receive a diagnostic interview for AUD and an individualized treatment plan.
  • Assessment of severe alcohol withdrawal complications should include clinical parameters such as past seizures or delirium tremens and the Prediction of Alcohol Withdrawal Severity Scale, with treatment including nonbenzodiazepine medications for low-risk patients and a short-term benzodiazepine prescription for high-risk patients, ideally in an inpatient setting.
  • All patients with AUD should be referred for psychosocial treatment, and those with moderate to severe AUD should be offered naltrexone, acamprosate, topiramate, or gabapentin, depending on contraindications and effectiveness.
  • Antipsychotics or SSRI antidepressants have little benefit and may worsen outcomes and should not be prescribed for AUD.

IN PRACTICE:

The authors noted that more than half of people aged 15 years or older in Canada drink more than the recommended amount, and about 18% meet the definition for AUD. “The aim of this guideline is to support primary care providers and services to offer more effective treatments routinely to patients with AUD as the standard of practice, with resulting improvements in health as well as potential for considerable cost savings in health and social systems,” the investigators write. They also note that policy makers can substantially improve standards of care by promoting adoption of the guideline and its recommendations.

SOURCE:

The article was written by Evan Wood, MD, PhD, professor of medicine, University of British Columbia, Vancouver, and colleagues. It was published online in the Canadian Medical Association Journal.

LIMITATIONS:

The guideline was published more than 3 years after the initial literature search in September 2020 and did not include comprehensive guidance for AUD with co-occurring substance use disorders or with severe mental health conditions. Certain groups, including immigrant and refugee populations, were not represented.

DISCLOSURES:

Development of the guideline received support from Health Canada’s Substance Use and Addictions Program, Canadian Institutes of Health Research, and BC Centre on Substance Use. No committee members disclosed direct monetary or nonmonetary support from alcohol or pharmaceutical industry sources within the past 5 years, or that their clinical revenue would be influenced by the guideline recommendations.

Here’s how to help Black smokers quit

Article Type

Wed, 10/25/2023 - 09:30

Black Americans attempt to quit smoking more often than their White counterparts but are less likely to succeed, and they pay the health consequences.

This knowledge has driven Kevin Choi, MD, acting scientific director of the National Institute on Minority Health and Health Disparities in Bethesda, Md., to dedicate his career to studying the patterns and disparities of smoking among these patients.

Dr. Choi wants primary care clinicians to know not just that they have the potential to educate patients on the harms of smoking – most patients already know smoking is unhealthy – but that aiding them will likely necessitate more assertive follow-up.

To do so, “we need to understand the bigger backdrop of racial and sociological stress experienced by the Black population, which stems from both interpersonal and structural racism,” Dr. Choi said.

Not only are Black smokers more likely to try to quit, but they also tend to smoke fewer cigarettes per day than other racial groups. Yet they experience higher rates of smoking-related mortality.
 

The reasons behind the attempts

Multiple factors play into Black smokers’ lower rates of successful quitting attempts than Asian, Hispanic, White, and Native American individuals.

One reason: An estimated 85% of Black smokers smoke highly addictive menthol cigarettes. According to Dr. Choi and other experts, the tobacco industry engages in targeted marketing of menthols by sponsoring community events in predominantly Black neighborhoods and colleges with historically Black populations and by using Black culture in advertising.

“The built environment really drives a change in behavior, and we have seen that chronically in the African American population being overly targeted and now being overly addicted to nicotine,” said Daniel Kortsch, MD, a family medicine physician and chair of the Tobacco Cessation Workgroup at Denver Health.

Menthol cigarettes are more addictive than traditional cigarettes, in part because they provide a less harsh feeling in the respiratory system, owing to anti-tussive, anti-irritant, and cooling properties that act as a cough suppressant and mask irritation and pain.

“You do not feel like you’re smoking that much or that it’s dangerous, and that’s exactly the reason why it’s harder to quit,” said Julia Adamian, MD, section chief of general internal medicine and clinical innovation at NYU Langone Tisch Hospital.

In addition, menthol cigarettes interact with the body in complex ways that make quitting harder, according to a study published in Nicotine & Tobacco Research. Menthol increases the amount of nicotine that the body absorbs and thus increases the risk of dependence on the drug.

According to Dr. Choi, rates of cigar and cigarillo use are higher among Black Americans, compared with other races, and these products are often left out of cessation programs. Smokers, regardless of race, may have a misguided belief that cigars and cigarillos are less harmful than cigarettes.

Research published in 2021 found that Black cigar smokers who were interested in cessation had not been asked by their health care provider if they smoked cigars, and those who were asked reported a lack of support for cessation.

Primary care providers should work to remove any misconceptions a patient has regarding the safety of cigarillos and cigars, Dr. Choi said.

These smokers are also at a disadvantage regarding cessation success because of the neighborhoods they may live in, according to Dr. Choi. Black Americans are more likely to earn less and to live in neighborhoods with lower housing values than other racial groups. Areas with more low-income households tend to have a higher density of tobacco outlets.

“If you’re trying to quit smoking, but you walk by three, four, or five gas stations, convenience stores, and other tobacco outlets with signs that advertise sales, it’s not going to make quitting easy,” Dr. Choi said.
 

 

 

Tailoring treatment to Black smokers

Considering the unique challenges Black patients may face in quitting, clinicians should provide more follow-up and consistent support, according to Dr. Adamian. The higher risk of tobacco-related death among Black smokers means clinicians need to be more aggressive in recommending every treatment possible if one treatment fails.

Pharmacotherapy, nicotine replacement therapy, and counseling are evidence-based options to help patients stop smoking.

Dr. Kortsch considers pharmacotherapy to be the most effective and evidence-based treatment for nicotine addiction. However, Black Americans are less likely than White smokers to try smoking cessation medications, and they express more suspicion about efficacy and potential addiction to the tools.

“African American populations simply do not use pharmacotherapy to the extent that other populations do to help them quit smoking; this is a problem,” Dr. Kortsch said.

Dr. Kortsch recommends the use of varenicline for all patients with nicotine addiction. He recommends varenicline in combination with tobacco replacement products such as lozenges, patches, gums, or inhalers if the patient is a heavy smoker as opposed to someone who has a few cigarettes on the weekends.

If a patient has anxiety or depression, Dr. Adamian advises initiating a pharmacologic treatment such as bupropion or varenicline more quickly, because mood disorders can hinder cessation.

Cessation counseling is another option, but clinicians may need to more thoroughly explain what it entails. According to Dr. Choi, Black patients may be more reluctant to try cessation counseling because of the negative stigma associated with the term “counseling.” But this treatment is not therapy – it involves identifying and coming up with strategies to manage smoking triggers and providing encouragement. Clinicians can eliminate any confusion patients may have between psychological therapy and cessation counseling.

“ ‘Counseling’ tends to have a somewhat negative connotation among racial minority populations, like you go to counseling because you’re crazy,” Dr. Choi said. “That needs to change.”

Clinicians also must clarify how each cessation tool works. For example, some patients may not realize that the nicotine patch isn’t an instant fix for a craving and that hours may pass before the user feels its effects, according to Dr. Choi.
 

Move past the ‘advise’ stage

While recommending to patients various forms of cessation, clinicians should be mindful of the U.S. Preventive Services Task Force’s guidelines for providers who treat patients who smoke. Those guidelines include a five-step process: Ask, Advise, Assess, Assist, and Arrange.

Dr. Choi said most providers stop at the “Advise” stage. In steps one and two, providers ask patients whether they smoke, then advise them to quit. Stage three involves asking whether or not a patient is ready to quit and where they are in their journey.

Clinicians shouldn’t give up when patients say they do not currently plan to quit. Instead, they can use the conversation to create an ongoing dialogue about the patient’s readiness to quit in future visits. Follow-up phone calls or text messages should be made 2-4 weeks after a patient makes an attempt to quit and at the same interval thereafter, Dr. Adamian advised.

“It takes a concerted effort on behalf of all people to be successful, and it is really uncommon for someone to be successful with only one attempt,” Dr. Kortsch said.

In a recent study published in the Journal of the American Medical Association, researchers identified three key factors that influence a Black smoker’s ability to stop smoking in early attempts. These factors have been shown to increase the chances of long-term cessation: fewer cigarettes per day, nonuse of other tobacco products, and lower levels of cotinine (a nicotine metabolite) at baseline.

“Using these predictors of early treatment response could allow providers to anticipate which smokers may benefit from a minimal, low-cost intervention and who may benefit from more intensive treatment,” said Eleanor Leavens, PhD, assistant professor in the department of population health at the University of Kansas School of Medicine, Kansas City, who led the study.

Dr. Leavens’ research also confirmed that early abstinence predicts long-term cessation success. Smokers who were able to forgo cigarettes within 2 weeks of their quit date were almost four times more likely to remain abstinent over the long term.

A quick phone call or message from the clinician or a staff member can help patients achieve early progress, enable changes in approach to quitting, and build a relationship with the patient, Dr. Adamian said.

“Have more empathy for what Black patients are going through,” Dr. Choi said. “Continue to cheer them on and to be a supporter of their smoking cessation journey.”

Mon, 10/23/2023 - 16:11

 

TOPLINE:

The use of lysergic acid diethylamide (LSD) tripled among young adults with past-year depression, results from the annual National Survey on Drug Use and Health (NSDUH) show. The increase was especially high among young adults and those earning less than $75,000 a year.

METHODOLOGY:

  • Investigators analyzed responses of 478,500 adult respondents to the NSDUH, a cross-sectional, in-person survey administered by the Substance Abuse and Mental Health Services Administration between 2008 and 2019.
  • Respondents were questioned about past-month and past-year LSD use and past-year depression.
  • Investigators conducted statistical analysis between December 2022 and June 2023.

TAKEAWAY:

  • Past-year use of LSD increased significantly more among adults with major depression, increasing from 0.5% in 2008 to 1.8% in 2019 (prevalence difference, 1.3% [95% confidence interval, 1.0%-1.6%]) compared with adults without major depression.
  • This difference was particularly pronounced among young adults with depression age 34 years or younger (PD for age 18-25 years, 3.3% [95% CI, 2.5%-4.2%]; PD for age 26-34 years, 2.7% [95% CI, 1.6%-3.8%]).
  • The increase was also higher among those earning less than $75,000 per year (PD for < $20,000, 1.9% [95% CI, 1.3%-2.6%]; PD for $20,000-$49,999, 1.5% [95% CI, 1.0%-2.1%]; PD for $50,000-$74,999, 1.3% [95% CI, 0.7%-2.0%]).
  • Use of other hallucinogen classes either decreased or increased only among select age groups or time frames; the use of LSD consistently increased among every observed age group from 2002 to 2019.

IN PRACTICE:

“Future research should aim to understand the motivations for LSD use as well as the directionality between nonmedical LSD use and depression. As the evaluation of LSD as a potential psychiatric treatment continues, public health efforts to promote safe and evidence-based use of psychedelics are critical,” the investigators write.

TOPLINE:

The use of lysergic acid diethylamide (LSD) tripled among young adults with past-year depression, results from the annual National Survey on Drug Use and Health (NSDUH) show. The increase was especially high among young adults and those earning less than $75,000 a year.

METHODOLOGY:

  • Investigators analyzed responses of 478,500 adult respondents to the NSDUH, a cross-sectional, in-person survey administered by the Substance Abuse and Mental Health Services Administration between 2008 and 2019.
  • Respondents were questioned about past-month and past-year LSD use and past-year depression.
  • Investigators conducted statistical analysis between December 2022 and June 2023.

TAKEAWAY:

  • Past-year use of LSD increased significantly more among adults with major depression, increasing from 0.5% in 2008 to 1.8% in 2019 (prevalence difference, 1.3% [95% confidence interval, 1.0%-1.6%]) compared with adults without major depression.
  • This difference was particularly pronounced among young adults with depression age 34 years or younger (PD for age 18-25 years, 3.3% [95% CI, 2.5%-4.2%]; PD for age 26-34 years, 2.7% [95% CI, 1.6%-3.8%]).

Why legal pot makes this physician sick

Article Type

Thu, 10/19/2023 - 12:07

Last year, my husband and I took a 16-day road trip from Kentucky through Massachusetts to Maine. On our first morning in Boston, we exited the Park Street Station en route to Boston Common, but instead of being greeted by the aroma of molasses, we were hit full-on with a pungent, repulsive odor. “That’s skunk weed,” my husband chuckled as we stepped right into the middle of the Boston Freedom Rally, a celebration of all things cannabis.

As we boarded a hop-on-hop-off bus, we learned that this was the one week of the year that the city skips testing tour bus drivers for tetrahydrocannabinol (THC), “because we all test positive,” the driver quipped. As our open-air bus circled the Common, a crowd of pot enthusiasts displayed signs in support of relaxed regulation for public consumption.

The 34-year-old Boston Freedom Rally is a sign that U.S. culture has transformed forever. Mary Jane is no friend of emergency physicians nor of staff on hospital wards and offices. Health care workers should brace for the true impact of THC as its adoption by all ages rises.
 

Toking boomers and millennials

Researchers at the University of California, San Diego, looked at cannabis-related emergency department visits from all acute-care hospitals in the state from 2005 to 2019 and found an 1,808% increase in patients aged 65 or older (that is not a typo) who were there for complications from cannabis use.

The lead author said in an interview that, “older patients taking marijuana or related products may have dizziness and falls, heart palpitations, panic attacks, confusion, anxiety or worsening of underlying lung diseases, such as asthma or [chronic obstructive pulmonary disease].”

A recent study from Canada suggests that commercialization has been associated with an increase in related hospitalizations, including cannabis-induced psychosis.

According to a National Study of Drug Use and Health, marijuana use in young adults reached an all-time high (pun intended) in 2021. Nearly 10% of eighth graders and 20% of 10th graders reported using marijuana this past year.

The full downside of any drug, legal or illegal, is largely unknown until it infiltrates the mainstream market, but these are the typical cases we see:

Let’s start with the demotivated high school honors student who dropped out of college to work at the local cinema. He stumbled and broke his clavicle outside a bar at 2 AM, but he wasn’t sure if he passed out, so a cardiology consult was requested to “rule out” arrhythmia associated with syncope. He related that his plan to become a railway conductor had been upended because he knew he would be drug tested and just couldn’t give up pot. After a normal cardiac exam, ECG, labs, a Holter, and an echocardiogram were also requested and normal at a significant cost.
 

Cannabinoid hyperemesis syndrome

One of my Midwest colleagues related her encounter with two middle-aged pot users with ventricular tachycardia (VT). These episodes coincided with potassium levels less than 3.0 mEq/L in the setting of repetitive vomiting. The QTc interval didn’t normalize despite a corrected potassium level in one patient. They were both informed that they should never smoke pot because vomiting would predictably drop their K+ levels again and prolong their QTc intervals. Then began “the circular argument,” as my friend described it. The patient claims, “I smoke pot to relieve my nausea,” to which she explains that “in many folks, pot use induces nausea.” Of course, the classic reply is, “Not me.” Predictably one of these stoners soon returned with more VT, more puking, and more hypokalemia. “Consider yourself ‘allergic’ to pot smoke,” my friend advised, but “was met with no meaningful hint of understanding or hope for transformative change,” she told me.

I’ve seen cannabinoid hyperemesis syndrome several times in the past few years. It occurs in daily to weekly pot users. Very rarely, it can cause cerebral edema, but it is also associated with seizures and dehydration that can lead to hypovolemic shock and kidney failure.
 

Heart and brain harm

Then there are the young patients who for various reasons have developed heart failure. Unfortunately, some are repetitively tox screen positive with varying trifectas of methamphetamine (meth), cocaine, and THC; opiates, meth, and THC; alcohol, meth, and THC; or heroin, meth, and THC. THC, the ever present and essential third leg of the stool of stupor. These unfortunate patients often need heart failure medications that they can’t afford or won’t take because illicit drug use is expensive and dulls their ability to prioritize their health. Some desperately need a heart transplant, but the necessary negative drug screen is a pipe dream.

And it’s not just the heart that is affected. There are data linking cannabis use to a higher risk for both ischemic and hemorrhagic stroke. A retrospective study published in Stroke, of more than 1,000 people diagnosed with an aneurysmal subarachnoid hemorrhage, found that more than half of the 46 who tested positive for THC at admission developed delayed cerebral ischemia (DCI), which increases the risk for disability or early death. This was after adjusting for several patient characteristics as well as recent exposure to other illicit substances; cocaine, meth, and tobacco use were not associated with DCI.
 

Natural my ...

I’m certain my anti-cannabis stance will strike a nerve with those who love their recreational THC and push for its legal sale; after all, “It’s perfectly natural.” But I counter with the fact that tornadoes, earthquakes, cyanide, and appendicitis are all natural but certainly not optimal. And what we are seeing in the vascular specialties is completely unnatural. We are treating a different mix of complications than before pot was readily accessible across several states.

Our most effective action is to educate our patients. We should encourage those who don’t currently smoke cannabis to never start and those who do to quit. People who require marijuana for improved quality of life for terminal care or true (not supposed) disorders that mainstream medicine fails should be approached with empathy and caution.

A good rule of thumb is to never breathe anything you can see. Never put anything in your body that comes off the street: Drug dealers who sell cannabis cut with fentanyl will be ecstatic to take someone’s money then merely keep scrolling when their obituary comes up.

Let’s try to reverse the rise of vascular complications, orthopedic injuries, and vomiting across America. We can start by encouraging our patients to avoid “skunk weed” and get back to the sweet smells of nature in our cities and parks.

Some details have been changed to protect the patients’ identities, but the essence of their diagnoses has been preserved.

Cannabis use growing among menopausal women

Article Type
Changed
Mon, 10/16/2023 - 09:15

PHILADELPHIA – About two in five perimenopausal or postmenopausal women have ever used cannabis in any form, but 10% have used it in the past month, according to cross-sectional survey results presented at the annual meeting of the Menopause Society (formerly The North American Menopause Society).

Though most women reported using cannabis for recreational reasons, 13% used it only for medical reasons, most often for chronic pain, anxiety, sleep, and stress.

“These findings highlight the importance of recognizing and discussing cannabis use in the health care setting, and the need for additional research to evaluate the potential harms and/or benefits of use in this vulnerable population,” Carolyn J. Gibson, PhD, MPH, a staff psychologist in women’s health at the San Francisco VA Health Care System and an assistant professor of psychiatry and behavioral sciences at the University of California, San Francisco, told attendees.

As cannabis has become more accessible, with its use legalized in 38 states and Washington, D.C., the proportion of U.S. adults using it has doubled over about a decade, from 6% in 2007 to 12% in 2019, Dr. Gibson said. Further, women aged 50 and older are among the fastest-growing groups of users of cannabis, and it’s being increasingly used – and marketed – for treating menopause-related and aging-related symptoms, including insomnia, anxiety, and chronic pain, she said.

“With these decisions to use cannabis, medically or for these other purposes, there’s this perception that it’s harmless,” Dr. Gibson said. Yet potential health risks associated with cannabis include the usual health effects associated with any kind of smoking as well as dependence in those who use it more frequently and/or develop a tolerance for it. She noted that average THC potency has increased over time, and acute risks for using cannabis with high levels of THC – at least 15% or at least 10 mg – can include anxiety/panic, confusion, disturbing/intrusive thoughts, psychosis, and effects on coordination and cognition. She also acknowledged, however, that most of the data available on risks come from studies of men and younger adults rather than older women.

Given the growing normalization of cannabis use, Dr. Gibson’s team sought to better understand prevalence of use as well as types of use and reasons for use in perimenopasual and postmenopausal women. They analyzed data from a cross-sectional survey of women and gender-diverse members, aged 45-64, of Ipsos KnowledgePanel, an online panel with more than 60,000 participating members in the United States.

All the respondents identified themselves as female at birth and had not used gender-affirming therapy or undergone gender-affirming surgery. The survey included questions on sociodemographics, menopause status, frequency of cannabis use, types of cannabis used, reasons for using cannabis, and use of cannabis in the previous 30 days. The 5,174 respondents were an average 55 years old and predominantly non-Hispanic white (63%), with 13% non-Hispanic Black and 16% Hispanic. Two-thirds of the women reported working full- or part-time (67%) and two-thirds were postmenopausal (68%), with 64% reporting experiencing menopause symptoms.

About two in five respondents (42%) had ever used cannabis in any form, most often smoking it (83%) or consuming edibles (51%). Among those who had ever used it, 30% reported having smoked it daily or nearly daily for at least a year at some point.

Ten percent of respondents had used cannabis in the past month, again primarily smoking (56%) or edibles (52%), though 39% said they used it in more than one form, including vaping, dabbing, or topical use. Nearly half (46%) of the respondents who smoked cannabis recently did not know the THC potency of what they consumed, and just over 20% of those consuming edibles didn’t know the THC potency of what they used. However, about a third of those taking edibles used cannabis with less than 10 mg of THC, and a little over a quarter used edibles with 10 mg of THC.

Within the 10% who had used cannabis in the past month, nearly a third (31%) of respondents – or around 3.1% of the total sample – reported smoking cannabis daily or almost daily, and 19% (or 1.9% of the overall sample) consumed cannabis edibles daily or almost daily.

Most of the respondents who used cannabis said it was for recreational use (62%), but a quarter (25%) reported using it for both recreational and medical reasons, and 13% used it only for medical reasons. The most common reason women used cannabis was to treat chronic pain (28%), followed by nearly as many women reporting cannabis use for anxiety (24%), sleep (22%), and stress (22%). Six percent of women used cannabis specifically for menopause-related sleep and mood problems.

Given the growing use of cannabis in this population and the dearth of data on its effects in older women, Dr. Gibson highlighted the need for research examining the potential benefits and harms of cannabis for menopausal women.
 

 

 

Not risk-free

“What did surprise me was that nearly a third reported daily use for at least 1 year and that 38% were medical marijuana users, not just recreational,” Dr. Reed said in an interview. The proportions of women using cannabis for menopausal symptoms or using it daily are concerning, she added.

“These individuals are at risk for dependence and health risks related to marijuana use,” Dr. Reed said. “Providers should always ask patients about OTC products, herbals, supplements, cannabis use, and alternative management of menopausal symptoms to better understand patient preferences for menopausal symptom therapies, so that treatment plans can be discussed with individual patient preferences in mind. We need to start with where the patient is coming from.”

Data presented throughout the conference has shown how people are “disillusioned with the care they are receiving for menopause,” Dr. Reed added. “It is so difficult to distinguish truth from myths based on information gained through social media, family, and friends, and that often is where most people are getting their information.”

Physicians often have not received adequate training on how to provide people with accurate information about menopause and managing menopausal symptoms, so she advises patients and physicians to visit reliable sites such as the Menopause Society, the Swan Study, and My Menoplan.

PHILADELPHIA – About two in five perimenopausal or postmenopausal women have ever used cannabis in any form, but 10% have used it in the past month, according to cross-sectional survey results presented at the annual meeting of the Menopause Society (formerly The North American Menopause Society).

Though most women reported using cannabis for recreational reasons, 13% used it only for medical reasons, most often for chronic pain, anxiety, sleep, and stress.

“These findings highlight the importance of recognizing and discussing cannabis use in the health care setting, and the need for additional research to evaluate the potential harms and/or benefits of use in this vulnerable population,” Carolyn J. Gibson, PhD, MPH, a staff psychologist in women’s health at the San Francisco VA Health Care System and an assistant professor of psychiatry and behavioral sciences at the University of California, San Francisco, told attendees.

As cannabis has become more accessible, with its use legalized in 38 states and Washington, D.C., the proportion of U.S. adults using it has doubled over about a decade, from 6% in 2007 to 12% in 2019, Dr. Gibson said. Further, women aged 50 and older are among the fastest-growing groups of users of cannabis, and it’s being increasingly used – and marketed – for treating menopause-related and aging-related symptoms, including insomnia, anxiety, and chronic pain, she said.

“With these decisions to use cannabis, medically or for these other purposes, there’s this perception that it’s harmless,” Dr. Gibson said. Yet potential health risks associated with cannabis include the usual health effects associated with any kind of smoking as well as dependence in those who use it more frequently and/or develop a tolerance for it. She noted that average THC potency has increased over time, and acute risks for using cannabis with high levels of THC – at least 15% or at least 10 mg – can include anxiety/panic, confusion, disturbing/intrusive thoughts, psychosis, and effects on coordination and cognition. She also acknowledged, however, that most of the data available on risks come from studies of men and younger adults rather than older women.

Given the growing normalization of cannabis use, Dr. Gibson’s team sought to better understand prevalence of use as well as types of use and reasons for use in perimenopasual and postmenopausal women. They analyzed data from a cross-sectional survey of women and gender-diverse members, aged 45-64, of Ipsos KnowledgePanel, an online panel with more than 60,000 participating members in the United States.

All the respondents identified themselves as female at birth and had not used gender-affirming therapy or undergone gender-affirming surgery. The survey included questions on sociodemographics, menopause status, frequency of cannabis use, types of cannabis used, reasons for using cannabis, and use of cannabis in the previous 30 days. The 5,174 respondents were an average 55 years old and predominantly non-Hispanic white (63%), with 13% non-Hispanic Black and 16% Hispanic. Two-thirds of the women reported working full- or part-time (67%) and two-thirds were postmenopausal (68%), with 64% reporting experiencing menopause symptoms.

About two in five respondents (42%) had ever used cannabis in any form, most often smoking it (83%) or consuming edibles (51%). Among those who had ever used it, 30% reported having smoked it daily or nearly daily for at least a year at some point.

Ten percent of respondents had used cannabis in the past month, again primarily smoking (56%) or edibles (52%), though 39% said they used it in more than one form, including vaping, dabbing, or topical use. Nearly half (46%) of the respondents who smoked cannabis recently did not know the THC potency of what they consumed, and just over 20% of those consuming edibles didn’t know the THC potency of what they used. However, about a third of those taking edibles used cannabis with less than 10 mg of THC, and a little over a quarter used edibles with 10 mg of THC.

Within the 10% who had used cannabis in the past month, nearly a third (31%) of respondents – or around 3.1% of the total sample – reported smoking cannabis daily or almost daily, and 19% (or 1.9% of the overall sample) consumed cannabis edibles daily or almost daily.

Most of the respondents who used cannabis said it was for recreational use (62%), but a quarter (25%) reported using it for both recreational and medical reasons, and 13% used it only for medical reasons. The most common reason women used cannabis was to treat chronic pain (28%), followed by nearly as many women reporting cannabis use for anxiety (24%), sleep (22%), and stress (22%). Six percent of women used cannabis specifically for menopause-related sleep and mood problems.

Given the growing use of cannabis in this population and the dearth of data on its effects in older women, Dr. Gibson highlighted the need for research examining the potential benefits and harms of cannabis for menopausal women.

Growing ‘tranq’ threat poses challenges for PCPs

Article Type
Changed
Tue, 10/17/2023 - 12:36

The widening threat of the animal tranquilizer xylazine, otherwise known as tranq, which has been found in illegally manufactured fentanyl, necessitates wider testing, a better understanding of its effects, and more research on treatment options, according to a narrative review published in the Annals of Internal Medicine.

“A lot of doctors and providers are asking about this drug,” said Joseph D’Orazio, MD, an addiction medicine specialist and medical toxicologist at Cooper University Healthcare, Camden, N.J., who led the review.

Xylazine is believed to prolong or intensify the effects of opioids, making it a popular additive to illegally produced opioids, particularly fentanyl, according to the Drug Enforcement Administration. Users end up in a zombie-like state with slowed breathing, and they sometimes develop skin ulcers. Because xylazine is not an opioid, common antidotes such as naloxone are ineffective. The White House has called the fentanyl-xylazine combo an “emerging threat.”

“Xylazine is making the deadliest drug threat our country has ever faced, fentanyl, even deadlier,” said DEA administrator Anne Milgram, in a statement on the agency’s website. “DEA has seized xylazine and fentanyl mixtures in 48 of 50 States. The DEA Laboratory System is reporting that in 2022 approximately 23% of fentanyl powder and 7% of fentanyl pills seized by the DEA contained xylazine.”

Dr. D’Orazio paired clinical experience with available research to provide guidance on the care of patients exposed to xylazine.

He and his team issued a call for more research on the drug’s effects, including more details on dependency and withdrawal.

Testing a patient who may have been exposed to xylazine requires forensic lab capabilities, which makes testing complicated and costly. The review found no evidence of the origin of the drug or why it causes open sores.

The review calls for more education of providers, including primary care physicians, on the treatment and care of patients who have used xylazine and fentanyl. The authors also call for expanding standard urine analysis to test for xylazine and for intensifying surveillance of the drug supply and distribution of xylazine test strips.

The authors of an editorial that accompanied the journal article urged the health care community to get ahead of xylazine before the crisis worsens.

“Not testing for xylazine in current unaffected areas and populations may lead to delays in responding if and when the drug becomes prevalent in the drug supply,” the authors wrote.

Xylazine was detected in 90% of street opioid samples tested in Philadelphia in 2021, and a toxic surveillance study of drug paraphernalia in Maryland found xylazine in 80% of samples tested between 2021 and 2022.

Dr. D’Orazio stressed that although Narcan is ineffective in treating xylazine, because the sedative is almost always mixed with fentanyl or another opiate, the opioid antagonist should still be used in emergencies.

Angelique Campen, MD, an emergency medicine physician at Providence St. Joseph Medical Center, Burbank, Calif., said she has seen an increase in patients entering the emergency department under the influence of what seems like fentanyl or heroin, but standard treatments such as Narcan have a limited effect. These patients remain in a prolonged period of sedation.

Recently, she admitted to her hospital’s intensive care unit a patient suspected of a xylazine overdose who was not responding to treatment.

Dr. Campen said that patients are screened for fentanyl, but because no test is available for xylazine, she presumed xylazine was causing the complication.

“It makes perfect medical sense to me that that’s what was going on,” Dr. Campen, who has worked at St. Joseph’s for 25 years, said. “I’m hoping with physicians being more aware of it that we can have that part of our regular urine drug screen.”

Dr. Campen also said she hopes an antidote is soon developed.

“If we can just keep delivering that message, hopefully, [to] more and more people, it will get through to them,” she said. “Every time you’re taking this, even though you may have taken it a week before and been fine, you never know: The next dose you take may be the lethal dose.”

A review author reports being awarded $1,000 to cover travel cost for Best Overall Abstract at the American Society of Addiction Medicine 2023 Annual Meeting. Another author reports receiving payments for training conducted as part of a NJDMAHS training grant to educate on substance use disorders. Dr. D’Orazio reports a $500 honorarium for a one-time lecture on xylazine at Yale; and a $500 honorarium for speaking one to three times per year on various topics regarding opioid use disorder at the Health Federation of Philadelphia. No other disclosures were reported.

Substance-induced psychosis tied to schizophrenia risk

Article Type
Changed
Fri, 10/06/2023 - 16:31

 

TOPLINE:

Individuals who visited the ER for substance-induced psychosis had a 160% greater risk of developing a schizophrenia spectrum disorder (SSD), compared with the general population, new research shows. Three years after an initial ER visit, 18.5% of those with substance-induced psychosis were diagnosed with an SSD. Cannabis-induced psychosis was associated with the greatest risk.

METHODOLOGY:

  • In this retrospective, population-based cohort study, investigators evaluated the risk of transition to a diagnosis of SSD for individuals with an ER visit for substance use versus the general population.
  • Investigators at The Ottawa Hospital and the Institute for Clinical Evaluative Sciences, both in Ontario, analyzed data from six linked databases containing health information on nearly 10 million Ontario residents aged 14-65 years eligible for medical coverage.
  • Investigators collected the health data between January 2008 and March 2022 on residents with substance use–related ER visits with, and without, psychosis.

TAKEAWAY:

  • There were nearly 408,000 individuals with an ER visit for substance use, of which 13,800 (3.4%) of the visits were for substance-induced psychosis.
  • Individuals with substance-induced psychosis were at a 163-fold (age- and sex-adjusted hazard ratio, 163.2; 95% confidence interval, 156.1-170.5) increased risk of transitioning to an SSD, relative to the general population (3-year risk, 18.5% vs. 0.1%).
  • Individuals with an ER visit for substance use without psychosis had a lower relative risk of transitioning (aHR, 9.8; 95% CI, 9.5-10.2; 3-year risk, 1.4%) but incurred more than three times the absolute number of transitions (9,969 vs. 3,029).
  • ER visits related to cannabis use had the highest transition risk among visits with psychosis (aHR, 241.6; 95% CI, 225.5-258.9) and the third-highest risk among visits without psychosis (aHR, 14.3; 95% CI, 13.5-15.2).
  • Younger age and male sex were associated with a higher risk of transition, and the risk of male sex was greater in younger, compared with older, individuals particularly for cannabis use.

IN PRACTICE:

“Primary prevention efforts aimed at reducing substance use and substance use disorders could substantially reduce the population-level burden of chronic psychoses,” the investigators write. “Our findings also highlight the need for targeted secondary prevention providing early intervention and reducing substance use in the highest-risk groups, which may delay or prevent transition to schizophrenia spectrum disorders.”

SOURCE:

Daniel T. Myran, MD, MPH, of the Ottawa Hospital Research Institute, led the study, which was funded by the Canadian Institutes of Health Research and the University of Ottawa department of family medicine. The study was published online in JAMA Psychiatry.

LIMITATIONS:

Investigators did not have access to detailed data on substance-related outpatient visits or patterns of substance use, which could provide additional prognostic information.

DISCLOSURES:

Dr. Myran reported receiving grants from the Canadian Institutes of Health Research during the conduct of the study. Dr. Solmi reported receiving honoraria for participation on advisory boards or presentations from AbbVie, Angelini, Lundbeck, and Otsuka outside the submitted work. The remaining authors have disclosed no relevant financial relationships.

  • Investigators collected the health data between January 2008 and March 2022 on residents with substance use–related ER visits with, and without, psychosis.

TAKEAWAY:

  • There were nearly 408,000 individuals with an ER visit for substance use, of which 13,800 (3.4%) of the visits were for substance-induced psychosis.
  • Individuals with substance-induced psychosis were at a 163-fold (age- and sex-adjusted hazard ratio, 163.2; 95% confidence interval, 156.1-170.5) increased risk of transitioning to an SSD, relative to the general population (3-year risk, 18.5% vs. 0.1%).
  • Individuals with an ER visit for substance use without psychosis had a lower relative risk of transitioning (aHR, 9.8; 95% CI, 9.5-10.2; 3-year risk, 1.4%) but incurred more than three times the absolute number of transitions (9,969 vs. 3,029).
  • ER visits related to cannabis use had the highest transition risk among visits with psychosis (aHR, 241.6; 95% CI, 225.5-258.9) and the third-highest risk among visits without psychosis (aHR, 14.3; 95% CI, 13.5-15.2).
  • Younger age and male sex were associated with a higher risk of transition, and the risk of male sex was greater in younger, compared with older, individuals particularly for cannabis use.

IN PRACTICE:

“Primary prevention efforts aimed at reducing substance use and substance use disorders could substantially reduce the population-level burden of chronic psychoses,” the investigators write. “Our findings also highlight the need for targeted secondary prevention providing early intervention and reducing substance use in the highest-risk groups, which may delay or prevent transition to schizophrenia spectrum disorders.”

TOPLINE:

Individuals who visited the ER for substance-induced psychosis had a 160% greater risk of developing a schizophrenia spectrum disorder (SSD), compared with the general population, new research shows. Three years after an initial ER visit, 18.5% of those with substance-induced psychosis were diagnosed with an SSD. Cannabis-induced psychosis was associated with the greatest risk.

METHODOLOGY:

  • In this retrospective, population-based cohort study, investigators evaluated the risk of transition to a diagnosis of SSD for individuals with an ER visit for substance use versus the general population.
  • Investigators at The Ottawa Hospital and the Institute for Clinical Evaluative Sciences, both in Ontario, analyzed data from six linked databases containing health information on nearly 10 million Ontario residents aged 14-65 years eligible for medical coverage.
  • Investigators collected the health data between January 2008 and March 2022 on residents with substance use–related ER visits with, and without, psychosis.

TAKEAWAY:

  • There were nearly 408,000 individuals with an ER visit for substance use, of which 13,800 (3.4%) of the visits were for substance-induced psychosis.
  • Individuals with substance-induced psychosis were at a 163-fold (age- and sex-adjusted hazard ratio, 163.2; 95% confidence interval, 156.1-170.5) increased risk of transitioning to an SSD, relative to the general population (3-year risk, 18.5% vs. 0.1%).
  • Individuals with an ER visit for substance use without psychosis had a lower relative risk of transitioning (aHR, 9.8; 95% CI, 9.5-10.2; 3-year risk, 1.4%) but incurred more than three times the absolute number of transitions (9,969 vs. 3,029).

A street medicine view of tobacco use in patients with schizophrenia

Editor’s note: Readers’ Forum is a department for correspondence from readers that is not in response to articles published in Current Psychiatry. All submissions to Readers’ Forum undergo peer review and are subject to editing for length and style. For more information, contact [email protected].

Throughout my psychiatric clerkship, I (JWF) participated in street medicine, the practice of providing care to patients (typically those who are homeless) at the location they currently reside, such as in a homeless encampment or community shelter. Our clinical team drove to locations that provided housing for patients diagnosed with schizophrenia, where we assisted with medications and blood draws. I remember pulling up the first day and seeing someone outside smoking a cigarette. I soon learned that many people living in such situations were smokers, and that among the substances they used, tobacco was the most common.

One patient said the cigarettes helped him manage the “voices in his head” as well as some of the adverse effects from medication, such as parkinsonism and akathisia. I asked my attending physician about this and she explained that for some patients, using tobacco was a way to mitigate the positive symptoms of schizophrenia and make the adverse effects of their therapy, particularly extrapyramidal symptoms (EPS), more bearable. By the end of my 2-week rotation, I was sure of a trend: our patients with schizophrenia smoked incessantly. Near the end of my rotation, I asked a patient, “Why do you smoke”? The patient looked at me, puzzled, and replied: “I just do.” This exchange only piqued my curiosity, and I could not help but wonder: what is the relationship between tobacco use and schizophrenia? How is tobacco use related to the pathophysiology of schizophrenia? Does tobacco use among patients with schizophrenia ameliorate aspects of their psychosis? Street medicine offered me a window into a biomedically intriguing question, and I wanted to learn more.

What smoking does for patients with schizophrenia

The high prevalence of smoking among patients with schizophrenia (50% to 88%) greatly exceeds the rates of smoking among patients with other psychiatric illnesses.1,2 The role of smoking in relation to schizophrenia and other psychoses is multidimensional, and evidence implicates smoking as a risk factor for schizophrenia.3,4

Two mechanisms may help explain tobacco use in patients with schizophrenia: reducing the adverse effects of antipsychotic medications and promoting neural transmission of dopamine. Second-generation antipsychotics (SGAs) are a first-line treatment, but they can produce EPS, metabolic dysregulation, and blood disorders such as hyponatremia and (rarely) agranulocytosis (1% with clozapine).5 Compared to those who are nonsmokers, patients with schizophrenia who smoke are more likely to experience more severe symptoms (eg, hallucinations and delusions) and less severe EPS.5,6 Research suggests that exposure to polycyclic aromatic hydrocarbons released during smoking induces cytochrome P450 1A2, an enzyme that metabolizes antipsychotic medications such as haloperidol, clozapine, and olanzapine. Increased metabolism results in lower serum concentrations of antipsychotics, lower efficacy, and more severe positive symptoms.5,6

Additionally, tobacco is an activator of nicotinic acetylcholine receptors (nAChR).6 When these receptors become activated, dopamine is released. Dopamine serves as a mediator of reward for nicotine use. In the context of schizophrenia, tobacco use opposes the mechanism of action of SGAs, which is to block neural transmission of dopamine.6 The etiology of EPS is related to the blockade of postsynaptic dopamine release in the striatum.6 By activating nAChR, smoking induces a downstream release of dopamine that can alleviate iatrogenic EPS by restoring neural transmission of dopamine.6 Nicotine may also modulate alpha-7 nicotinic receptor dysfunction, and improve the ability to filter out irrelevant environmental stimuli (impaired sensory gating), which can be overwhelming for patients with schizophrenia. It also can improve cognitive dysfunction and attention by inducing the release of dopamine in mesocortical pathways.7 The implications of this neural pathway are significant because smoking is significantly greater in tobacco users who are diagnosed with schizophrenia compared to tobacco users who lack a psychiatric diagnosis.6,7 Smoking may enhance dopaminergic neural transmission to a far greater extent in tobacco users with schizophrenia compared to tobacco users who do not develop schizophrenia, which suggests intrinsic differences at the neuronal level. Neural differences between tobacco users with or without schizophrenia may synergize with smoking in clinically and biologically meaningful ways. These pathways require further research to support or disprove these hypotheses.

Aside from the dopaminergic system, mechanisms influencing tobacco use among patients with schizophrenia may also be related to nicotine’s mild antidepressant effects. Evidence suggests a clinically meaningful association between nicotine dependence and mood disorders, and this association may be due to the antidepressant effects of nicotine.8-13 Patients with schizophrenia may experience respite from depressive symptoms through their tobacco use, eventually leading to nicotine dependence.

Treatment of schizophrenia involves multimodal management of a patient’s life, including reducing maladaptive habits that are harmful to health. Chronic smoking in patients with schizophrenia is associated not only with atherosclerosis and cardiovascular disease, but also with poor neurologic functioning, such as significant impairment in attention, working memory, learning, executive function, reasoning, problem-solving and speed of processing.14 One study found that in patients with schizophrenia, smoking increased the 20-year cardiovascular mortality risk by 86%.15

Despite challenges to abstinence, smoking cessation should be discussed with these patients, especially given the high prevalence of smoking among this vulnerable population. Bupropion and varenicline have been studied in the context of smoking cessation among patients with schizophrenia. Data on varenicline are mixed. Smokers with schizophrenia who received bupropion showed higher rates of abstinence from smoking compared to those who received placebo.16

As part of the biopsychosocial model of clinical care, sociodemographic factors must be considered in assessing the relationship between tobacco use and schizophrenia, because a large proportion of patients diagnosed with schizophrenia are members of underrepresented minority groups.17 A PubMed database search using keywords “African American” or “Black,” “tobacco,” and “schizophrenia” located only 12 studies, most of which lacked relevance to this question. Han et al18 is 1 of the few studies to investigate sociodemographic factors as they relate to tobacco use among adults with psychoses. Social determinants of health and other confounding variables also need defining to truly distinguish causation from correlation, especially regarding tobacco use and its association with other health risk behaviors.19

Without the street medicine component of the medical school training I received, the pattern of smoking among patients with schizophrenia may have remained invisible or insignificant to me, as tobacco use is not permitted in the inpatient and outpatient academic settings. This experience not only raised insightful questions, but also emphasized the clinical value of seeing patients within their living environment.

Without the street medicine component of the medical school training I received, the pattern of smoking among patients with schizophrenia may have remained invisible or insignificant to me, as tobacco use is not permitted in the inpatient and outpatient academic settings. This experience not only raised insightful questions, but also emphasized the clinical value of seeing patients within their living environment.

Substance use in pregnancy linked to adverse CVD outcomes

Article Type
Changed
Tue, 09/26/2023 - 10:05

 

TOPLINE:

Women who use cocaine, cannabis, or other substances during pregnancy have increased risks of acute cardiovascular (CV) events while in the hospital for delivery, including more than double the risk of maternal mortality, a new study shows.

METHODOLOGY:

  • Using the National Inpatient Sample database to identify hospital deliveries between 2004 and 2018 and diagnostic codes to identify maternal substance use, researchers compared 955,531 pregnancies with accompanying substance use – the most common substances being cannabis and opioids, followed by stimulants – to over 60 million pregnancies in which there was no substance use.
  • The primary outcome was any CV event, including acute myocardial infarction, stroke, arrhythmia, endocarditis, any acute cardiomyopathy or heart failure, or cardiac arrest; other outcomes included maternal mortality and major adverse cardiac events (MACE).

TAKEAWAY:

  • Deliveries complicated by substance use increased from 1,126 per 100,000 deliveries in 2004 to 1,547 per 100,000 in 2018, peaking at 2,187 per 100,000 in 2014.
  • After the researchers controlled for patient demographics and CVD risk factors, results showed that pregnant women who used any substance (cannabis, opioids, methamphetamine, alcohol, tobacco, or cocaine) were more likely to experience a CVD event (adjusted odds ratio [aOR], 1.61; 95% confidence interval [CI], 1.53-1.70; P < .001), MACE (aOR, 1.53; 95% CI, 1.46-1.61; P < .001), or maternal mortality (aOR, 2.65; 95% CI, 2.15-3.25; P < .001) during hospitalization for delivery.
  • Those using amphetamine/methamphetamine had ninefold higher odds of cardiomyopathy or heart failure and more than sevenfold higher odds of cardiac arrest.

IN PRACTICE:

“For the wellbeing of pregnant women and their children, substance use needs to be considered an independent risk factor for CV events in pregnancy,” the authors wrote. They called for prenatal assessments by a multidisciplinary cardio-obstetrics team to try to decrease cardiac complications.

In an accompanying editorial by Abha Khandelwal, MD, department of medicine, Stanford (Calif.) University, and others, the authors said the findings “highlight the critical support required during pregnancy and postpartum” for substance users, which should include comprehensive medical care and social services as well as access to addiction medicine and treatment of co-occurring mental health disorders.

SOURCE:

The study was carried out by Kari Evans, MD, division of maternal fetal medicine, department of obstetrics and gynecology, University of Arizona, Phoenix. It was published online in the Journal of the American College of Cardiology: Advances.

LIMITATIONS:

Use of administrative databases may have resulted in underreporting of diagnoses. The researchers could not assess the association of dose, duration, method, or timing of use for any substance with CV events. They also could not examine the effect of vaping on maternal CV events or differentiate hospitalizations for delivery that were complicated by CV events from hospitalizations for CV events that prompted delivery. The data did not reflect the postpartum period, during which a high rate of adverse CV events occurs.

DISCLOSURES:

The authors and editorial writers have no relevant conflicts of interest.

Simultaneous marijuana, alcohol use linked to worse outcomes

Article Type
Changed
Wed, 09/20/2023 - 12:03

 

TOPLINE:

Young adults who simultaneously use alcohol and marijuana (SAM) consume more drinks, are high for more hours in the day, and report more negative alcohol-related consequences.

METHODOLOGY:

  • The 2-year study included 409 people aged 18-25 years with a history of simultaneous alcohol and marijuana use (50.9% were women; 48.2% were non-Hispanic White; 48.9% were college students).
  • Participants completed daily online surveys about substance use and negative substance-related consequences for 14 continuous days every 4 months.

TAKEAWAY:

  • Alcohol use was reported on 36.1% of survey days, marijuana use on 28.0%, and alcohol and marijuana use on 15.0%.
  • Negative substance-related consequences were reported on 28.0% of drinking days and 56.4% of marijuana days.
  • SAM use was reported in 81.7% of alcohol users and 86.6% of marijuana users.
  • On SAM use days, participants consumed an average of 37% more drinks, with 43% more negative alcohol consequences; were high for 10% more hours; and were more likely to feel clumsy or dizzy, compared with non-SAM use days.

IN PRACTICE:

“This finding should be integrated into psychoeducational programs highlighting the risk of combining alcohol and marijuana,” the authors write. “A more nuanced harm-reduction [approach] could also encourage young adults to closely monitor and limit the amount of each substance being used if they choose to combine substances.”

SOURCE:

The study was conducted by Anne M. Fairlie, PhD, University of Washington, Seattle, and colleagues, and funded by the National Institute on Alcohol Abuse and Alcoholism. The study was published online in Alcohol Clinical and Experimental Research.

LIMITATIONS:

Study participants were recruited based on their substance use and lived in a region where recreational marijuana is legal, so the findings may not be generalizable to other populations. Substance use and consequences were self-reported and subject to bias.

DISCLOSURES:

The authors have reported no relevant financial relationships.
