Linda Geddes Science correspondent Lead exposure during childhood may lead to reduced cognitive abilities in later life, meaning people experience symptoms of dementia sooner, data suggest. The study, one of the first to investigate the decades-long consequences of lead poisoning, suggests countries could face an explosion of people seeking support for dementia as individuals who were exposed to high lead levels during early life progress into old age. “In the US, and I would imagine the UK, the prime years when children were exposed to the most lead was in the 1960s and 70s. That’s when the most leaded gasoline was getting used, lead paint was still common, and municipal water systems hadn’t done much to clean up their lead,” said Prof John Robert Warren at the University of Minnesota in Minneapolis, who was involved in the research. “Those children who are now in their 40s, 50s and early 60s, will soon be entering the time of life when cognitive impairment and dementia are really common. So there’s this coming wave, potentially, of problems for the people who were most exposed.” Although scientists have long known that children and adults who are exposed to lead have poorer cognitive and educational outcomes, few studies have investigated the longer-term consequences. Warren and his colleagues combined data from the US-based longitudinal Health and Retirement Study (HRS), which has followed the brain health of thousands of adults over several decades, with census records to pinpoint where 1,089 of these individuals lived as children. They also mapped the locations of towns and cities that used lead pipes and had acidic or alkaline water – a proxy for high lead exposure. The research, published in Science Advances, revealed that people who lived in cities with lead-contaminated water as children had worse baseline cognitive functioning – a measure of their ability to learn, process information, and reason – at age 72, compared with those who did not. The difference was equivalent to being roughly eight years older. © 2022 Guardian News & Media Limited

By Katherine Ellison News organizations were quick to trumpet the recent findings of a small study suggesting that “magic mushrooms” could be part of a breakthrough treatment for alcoholism. It’s no wonder. Every year, alcohol abuse kills more than 140,000 Americans and affects millions more, with a steep increase in deaths in recent years, according to data published by the Centers for Disease Control and Prevention on Nov. 4. But excitement about the psilocybin study also raises a question: Why aren’t there more medical treatments for such an obviously devastating problem? “There is a desperate need for new medications, and there are many good avenues that we’re pursuing,” said Dorit Ron, a neurology professor at the University of California at San Francisco Medical Center, who has been studying potential treatments that include rapamycin, a drug designed to help transplant patients tolerate new organs. But getting promising new medications into the hands of doctors and their patients has proved difficult, said George Koob, director of the National Institute on Alcohol Abuse and Alcoholism (NIAAA), adding “it doesn’t go for lack of trying.” Lack of awareness by doctors, funding decisions by the pharmaceutical industry and the stigma surrounding alcoholism have all held up progress, he said. Can pills help? Ron and other researchers say medication can play a vital role in combating alcohol use disorder, the medical condition commonly known as alcoholism. But fewer than 2 percent of people with an alcohol addiction take medication for the condition, national surveys show, compared with 13.4 percent of those dealing with opioid addiction.

By Leo Sands Psilocybin, the active hallucinogen found in psychedelic mushrooms — also known as “magic mushrooms” — can effectively alleviate a severe bout of depression when administered in a single dose and combined with talk therapy, a new clinical study found. Adults with depression who were administered a single 25-miligram dose of psilocybin were more likely to experience significant improvements in their mental health — both immediately and for up to three months — than others who were randomly assigned smaller doses of the same drug, said the peer-reviewed study, which was published Wednesday in the New England Journal of Medicine. “There’s something about the psychedelic experience that leads to a rapid resolution of depression symptoms,” said James Rucker, a consultant psychiatrist at King’s College London who worked on the trial. “We don’t really know what that is at the moment, but it’s very different to standard antidepressants.” The trial’s findings could be an encouraging sign for the 16 million Americans estimated each year by the Centers for Disease Control and Prevention to have depression, many of whom struggle to find treatments that work for them. Its authors hope the study — which was relatively small, with just 79 participants receiving the 25 mg dose — will pave the way for eventual regulatory approval of psilocybin by the Food and Drug Administration for use as a drug against depression. The new study randomly assigned 233 adults with depression three doses of psilocybin — 25 mg, 10 mg and 1 mg — across 22 sites in 10 countries. The authors found that the group given the largest dose recorded the most significant improvements in their depression, both immediately and for several weeks after.

By Aimee Cunningham The death rate from alcohol use rose sharply in the United States in the first year of the pandemic. From 2019 to 2020, the rate of alcohol-induced deaths climbed 26 percent, from 10.4 per 100,000 people to 13.1 per 100,000, researchers report in a National Center for Health Statistics data brief published November 4. The rate of alcohol-induced deaths has generally increased yearly for the last two decades, but the annual uptick tended to be 7 percent or less. Deaths from alcoholic liver disease, which includes hepatitis and cirrhosis, were the most common driver of the increased rate. Deaths from mental and behavioral disorders due to alcohol use — mortality from dependence syndrome or withdrawal, for example — were the second most frequent contributor. The death rate from alcohol use jumped 26 percent overall from 2019 to 2020, a marked increase from previous years. Other researchers have reported that adults were drinking more frequently, and more heavily, early in the pandemic compared with the year before. There is also evidence of an increase in cases of alcoholic liver disease. A study at Johns Hopkins Hospital in Baltimore reported that 2.3 times as many patients with severe alcoholic liver disease and with recent unhealthy drinking were referred to their liver transplant center from July to December of 2020 compared with those months in 2019. © Society for Science & the Public 2000–2022.

Jon Hamilton Computer games designed to boost self-esteem appear to prolong the antidepressant benefits of the mind-bending anesthetic ketamine. A recent study of 154 people found that those who played games featuring smiling faces and positive messages remained free of depression up to three months after a ketamine infusion, a team reports in the American Journal of Psychiatry. People who got ketamine alone tended to relapse after a week or two. The results are important because "we need new approaches that help people get feeling better faster and help them stay feeling better," says Rebecca Price, an author of the study and an associate professor of psychiatry and psychology at the University of Pittsburgh. Established drugs like Prozac and Zoloft can take weeks to ease depression, and don't work for every patient. Ketamine can offer immediate relief, but the effects often fade after a few days or weeks. "And then returning for infusions over and over to keep that relief going can end up being really burdensome and costly," Price says, "and just isn't accessible to all patients." So Price and a team of researchers wanted to find a way to make ketamine's antidepressant effects last longer. They decided to focus on a common symptom of depression: low self-esteem and self-loathing. The team drew on research suggesting that ketamine temporarily causes certain brain areas to enter a state in which they form lots of new connections. During this period, the brain seems to be more receptive to learning and change. "So we tried to use that window of opportunity just after ketamine to strengthen associations specifically between the idea of me, myself, and positive information and attributes," Price says. © 2022 npr

By Elisabeth Egan BEVERLY HILLS, Calif. — When I pictured Matthew Perry, the actor frequently known as Chandler Bing, I saw him on the tangerine couch at Central Perk or seated on one of the twin recliners in the apartment he shared with Joey Tribbiani. In September, after arriving at his 6,300-square-foot rental house and being ushered through a driveway gate by his sober companion, I sat across from Perry, who perched on a white couch in a white living room, a world away from “Friends,” the NBC sitcom that aired for 10 seasons and catapulted all six of its stars into fame, fortune and infinite memes. Instead of the foosball table where Chandler, Joey, Monica, Phoebe, Rachel and Ross gathered, nudging each other through the first chapters of adulthood, Perry, 53, had a red felt pool table that looked untouched. There was plenty of light in the house, but not a lot of warmth. I have watched every episode of “Friends” three times — in prime time, on VHS and on Netflix — but I’m not sure I would have recognized Perry if I’d seen him on the street. If he was an ebullient terrier in those 1990s-era Must See TV days — as memorable for his full-body comedy as he was for the inflection that made “Can you BE any more [insert adjective]” the new “Gag me with a spoon” — he now seemed more like an apprehensive bulldog, with the forehead furrows to match. As his former co-star Lisa Kudrow confesses in the foreword to his memoir, “Friends, Lovers and the Big Terrible Thing,” the first question people ask about “Friends” is often “How’s Matthew Perry doing?” Perry answers that question in the book, which Flatiron will publish on Nov. 1, by starkly chronicling his decades-long cage match with drinking and drug use. His addiction led to a medical odyssey in 2018 that included pneumonia, an exploded colon, a brief stint on life support, two weeks in a coma, nine months with a colostomy bag, more than a dozen stomach surgeries, and the realization that, by the time he was 49, he had spent more than half of his life in treatment centers or sober living facilities. © 2022 The New York Times Company

by Carey Gillam and Aliya Uteuova For decades, Swiss chemical giant Syngenta has manufactured and marketed a widely used weed-killing chemical called paraquat, and for much of that time the company has been dealing with external concerns that long-term exposure to the chemical may be a cause of the incurable brain ailment known as Parkinson’s disease. Syngenta has repeatedly told customers and regulators that scientific research does not prove a connection between its weedkiller and the disease, insisting that the chemical does not readily cross the blood-brain barrier, and does not affect brain cells in ways that cause Parkinson’s. But a cache of internal corporate documents dating back to the 1950s reviewed by the Guardian suggests that the public narrative put forward by Syngenta and the corporate entities that preceded it has at times contradicted the company’s own research and knowledge. And though the documents reviewed do not show that Syngenta’s scientists and executives accepted and believed that paraquat can cause Parkinson’s, they do show a corporate focus on strategies to protect product sales, refute external scientific research and influence regulators. In one defensive tactic, the documents indicate that the company worked behind the scenes to try to keep a highly regarded scientist from sitting on an advisory panel for the US Environmental Protection Agency (EPA). The agency is the chief US regulator for paraquat and other pesticides. Company officials wanted to make sure the efforts could not be traced back to Syngenta, the documents show. And the documents show that insiders feared they could face legal liability for long-term, chronic effects of paraquat as long ago as 1975. One company scientist called the situation “a quite terrible problem” for which “some plan could be made … ”

By Fenit Nirappil A national shortage of Adderall has left patients who rely on the pills for attention-deficit/hyperactivity disorder scrambling to find alternative treatments and uncertain whether they will be able to refill their medication. The Food and Drug Administration announced the shortage last week, saying that one of the largest producers is experiencing “intermittent manufacturing delays” and that other makers cannot keep up with demand. Some patients say the announcement was a belated acknowledgment of a reality they have faced for months — pharmacies unable to fill their orders and anxiety about whether they will run out of a medication needed to manage their daily lives. Experts say it is often difficult for patients to access Adderall, a stimulant that is tightly regulated as a controlled substance because of high potential for abuse. Medication management generally requires monthly doctor visits. There have been other shortages in recent years. “This one is more sustained,” said Timothy Wilens, an ADHD expert and chief of child and adolescent psychiatry at Massachusetts General Hospital who said access issues stretch back to spring. “It’s putting pressure on patients, and it’s putting pressure on institutions that support the patients.” Erik Gude, a 28-year-old chef who lives in Atlanta, experiences regular challenges filling his Adderall prescription, whether it’s pharmacies not carrying generic versions or disputes with insurers. He has been off the medication for a month after his local pharmacy ran out.

By Jyoti Madhusoodanan Q: I recently started taking an S.S.R.I. antidepressant, but I have been confused about whether it’s safe to drink alcohol. Some internet sources say it’s fine, others say to avoid drinking completely. Help! For many health care providers who treat anxiety and depression, the concern about whether it’s safe — or even advised — to drink alcohol while taking an antidepressant is a common one. “Patients tell me all the time, ‘I’m going to be drinking with friends tonight, so I skipped a dose,’” said Dr. Sarah Ramsay Andrews, a psychiatrist at the Johns Hopkins University School of Medicine. But skipping a dose is never a good idea, said Dr. Jody Glance, an addiction medicine specialist at the University of Pittsburgh Medical Center Western Behavioral Health — even if you’re going out for cocktails with friends. “When people stop taking their medicines for a day or two, they often don’t resume, and that can lead to a relapse of anxiety or depression.” Besides, she added, how safe it is to drink while on antidepressants depends on the kind of antidepressant you’re taking — and for most people taking selective serotonin reuptake inhibitors (or S.S.R.I.s), an occasional drink likely won’t do much harm. There are, however, caveats to keep in mind. S.S.R.I. medications — which include citalopram (Celexa), sertraline (Zoloft) and escitalopram (Lexapro) — are the most commonly prescribed class of antidepressants. They are typically used to help treat depression, and can also be effective for other conditions like anxiety, obsessive compulsive disorder, certain phobias and even premenstrual dysphoric disorder. They work by increasing the levels of the brain chemical serotonin — which is thought to influence your mood and emotions, among other things — by blocking its removal after it carries messages in the brain. But unlike many other medications used to treat mood disorders — like the anxiety medication alprazolam (Xanax) or the tricyclic antidepressant amitriptyline (Elavil) — S.S.R.I.s are less likely to interact with alcohol than other kinds of drugs, Dr. Glance said. © 2022 The New York Times Company

Daniel Merino & Josjan Zijlmans As research into psychedelics and their medical uses makes a comeback, scientists are having to deal with the legacy – both scientific and social – of a 40-year nearly total freeze on psychedelics research. In this episode of “The Conversation Weekly” podcast, we speak with three experts about the early rise and fall of psychedelics in Western science and culture, how the mystical and often vague language of the ‘60s and '70s still pervades research today and what it’s like to actually run clinical trials using psilocybin. According to a poll done in the summer of 2022, nearly 30% of U.S. residents have tried at least one psychedelic drug in their lifetime. Whether from personal experience, hearing about the experiences of friends or widespread depictions in the media, many people will have either tried to describe a psychedelic trip or heard someone else describe one. The language commonly used in these descriptions is, for lack of a better word, often quite trippy. “A key function of the ego is to identify differentiation,” says Robin Carhart-Harris, a neurologist and psychologist at the University of California, San Francisco, and one of the world’s leading psychedelics researchers. “And when that function breaks down, it’s replaced with a sense of de-differentiation, a sense of unity, like everything is interconnected in a web of relationships. That’s not nothingness, it’s sort of everythingness.” Many psychedelics researchers use an approach called “the mystical framework” to assess psychedelic experiences. Researchers who use this framework give participants in psychedelics studies a survey as a way to define and categorize the experience. The survey asks participants to rate how strongly they felt certain phenomena during their trip, including feelings like the “certainty of encounter with ultimate reality (in the sense of being able to 'know’ and ‘see’ what is really real at some point during your experience).” © 2010–2022, The Conversation US, Inc.

By Ted Alcorn Oregon is a drinker’s paradise. The state boasts more craft distilleries than Kentucky and is second only to California in the number of wineries. Some call Portland “beervana” for its bevy of breweries. But Oregon also has among the highest prevalence of problem drinking in the country. Last year, 2,153 residents died of causes attributed to alcohol, according to the Oregon Health Authority — more than twice the number of people killed by methamphetamines, heroin and fentanyl combined. Sonja Grove, a retiree in Portland whose adult son drank himself to death in April 2020, feels the toll is overlooked compared with those of other drugs. “Alcoholism has sort of taken a back seat.” In 2021, confronted by these conflicting trends, as the pandemic raged on, Oregon lawmakers made it easier to drink. They permanently legalized the sale of to-go cocktails, which the Distilled Spirits Council of the United States called a “lifeline,” and increased the number of cases that wineries could ship directly to consumers. Reginald Richardson, director of the state’s Alcohol and Drug Policy Commission, described the policies as incongruent. “We obviously want to create an environment that’s pro-business, that helps the state to develop, but we’ve got this other thing,” he said. That disconnect is typical: Before Covid lockdowns, no state permitted bars or restaurants to deliver liquor to customers at home, according to a trade association. Now, 28 have relaxed the rules. In contrast, policies that experts consider most effective at curbing excessive drinking have been ignored. For example, even as alcohol-related deaths soared to record highs in the last few years, alcohol taxes have fallen to the lowest rates in a generation. Americans drank more during the pandemic, but national data on the change have only recently become available. Alcohol tax revenues collected by the U.S. Treasury Department rose by eight percent in the fiscal year that ended on Sept. 30, 2021, compared with the previous year, and remain well above pre-pandemic levels. © 2022 The New York Times Company

By Jackie Rocheleau After experimenting on a hen, his dog, his goldfish, and himself, dentist William Morton was ready. On Oct. 16, 1846, he hurried to the Massachusetts General Hospital surgical theater for what would be the first successful public test of a general anesthetic. His concoction of sulfuric ether and oil from an orange (just for the fragrance) knocked a young man unconscious while a surgeon cut a tumor from his neck. To the onlooking students and clinicians, it was like a miracle. Some alchemical reaction between the ether and the man’s brain allowed him to slip into a state akin to light sleep, to undergo what should have been a painful surgery with little discomfort, and then to return to himself with only a hazy memory of the experience. General anesthesia redefined surgery and medicine, but over a century later it still carries significant risks. Too much sedation can lead to neurocognitive disorders and may even shorten lifespan; too little can lead to traumatic and painful wakefulness during surgery. So far, scientists have learned that, generally speaking, anesthetic drugs render people unconscious by altering how parts of the brain communicate. But they still don’t fully understand why. Although anesthesia works primarily on the brain, anesthesiologists do not regularly monitor the brain when they put patients under. And it is only in the past decade that neuroscientists interested in altered states of consciousness have begun taking advantage of anesthesia as a research tool. “It’s the central irony” of anesthesiology, says George Mashour, a University of Michigan neuroanesthesiologist, whose work entails keeping patients unconscious during neurosurgery and providing appropriate pain management. Mashour is one of a small set of clinicians and scientists trying to change that. They are increasingly bringing the tools of neuroscience into the operating room to track the brain activity of patients, and testing out anesthesia on healthy study participants. These pioneers aim to learn how to more safely anesthetize their patients, tailoring the dose to individual patients and adjusting during surgery. They also want to better understand what governs the transitions between states of consciousness and even hope to crack the code of coma. © 2022 NautilusThink Inc, All rights reserved.

By Christina Jewett Juul Labs, fighting for its survival in the United States, on Tuesday tentatively agreed to pay $438.5 million to settle an investigation by nearly three dozen states over marketing and sales practices that they contend set off the nation’s teenage vaping crisis. The company said that it did not acknowledge any wrongdoing in the settlement, but that it was trying to “resolve issues from the past” while awaiting a decision by the Food and Drug Administration over whether it would be permitted to continue to sell its products. Juul has been trying to reposition itself as a seller of vaping products that could help adults quit smoking traditional cigarettes, in an effort to rehabilitate its tarnished reputation and improve its diminished market value. The tentative settlement prohibits the company from marketing to youth, funding education in schools and misrepresenting the level of nicotine in its products. But Juul had already discontinued several marketing practices and withdrawn many of its flavored pods that appealed to teenagers, under public pressure from lawmakers, parents and health experts a few years ago when the vaping crisis was at a peak. “We think that this will go a long way in stemming the flow of youth vaping,” William Tong, Connecticut’s attorney general, said at a news conference on Tuesday. “We are under no illusions and cannot claim that it will stop youth vaping. It continues to be an epidemic. It continues to be a huge problem. But we have essentially taken a big chunk out of what was once a market leader.” The multistate investigation found that the company appealed to young people by hiring young models, using social media to court teenagers and giving out free samples, he said. And, he added, the inquiry revealed that the company had a “porous” age verification system for its products and that 45 percent of its Twitter followers were ages 13 to 17. Jason Miyares, the attorney general for Virginia, pointed out in a statement that the company’s former strategy of selling flavors like mango and crème brûlée appealed to youth as did the sleek design of its device that was easy to conceal. One term of the settlement banned the company from depicting anyone under 35 in its marketing images, Mr. Miyares’ statement said. © 2022 The New York Times Company

Perspective by Steven Petrow A few weeks ago, I mentioned to a friend that I was interested in learning more about psychedelics, especially how they might help me with depression and anxiety. That’s a broad category of plant medicines including psilocybin (“magic”) mushrooms, MDMA (ecstasy), DMT (Dimitri or the Businessman’s Trip), ketamine (“special K”) and some others. I’d been hesitant to be open about my search, because I’m old enough to remember the warnings about “bad trips” that scramble your brain. Imagine my surprise when my friend told me he’d recently taken his first “trip,” which he described as life-changing. I asked him — a real estate developer living in Northern California, married with kids — why he decided to try a psychedelic substance. “My work felt increasingly stale and meaningless,” he explained to me over a beer. “Despite a massive amount of reflection and coaching around how to break the rut, I felt as though I was still off track.” He and the others who have used these medicines spoke on the condition of anonymity because most of these psychedelics are Schedule I substances, meaning they are illegal to manufacture, buy, possess or distribute. When I confided my interest in psychedelics to a few other friends, several said they had tried the drugs and experienced several benefits: from easing anxiety to finding spiritual insights to combating depression and, among some with cancer, helping to reduce the fear of dying. They are hardly outliers. According to a new YouGovAmerica study, “one in four Americans say they’ve tried at least one psychedelic drug,” amounting to some 72 million U.S. adults. (The study included the medicines mentioned earlier, plus LSD, mescaline and salvia.) Was I missing a beat by not getting onboard?

By Matt Richtel This article examines the increase in anxiety, depression, self harm and suicide among U.S. adolescents. Parents and teenagers dealing with these issues can find resources here. One morning in the fall of 2017, Renae Smith, a high school freshman on Long Island, N.Y., could not get out of bed, overwhelmed at the prospect of going to school. In the following days, her anxiety mounted into despair. “I should have been happy,” she later wrote. “But I cried, screamed and begged the universe or whatever godly power to take away the pain of a thousand men that was trapped inside my head.” Intervention for her depression and anxiety came not from the divine but from the pharmaceutical industry. The following spring, a psychiatrist prescribed Prozac. The medication offered a reprieve from her suffering, but the effect dissipated, so she was prescribed an additional antidepressant, Effexor. A medication cascade had begun. During 2021, the year she graduated, she was prescribed seven drugs. These included one for seizures and migraines — she experienced neither, but the drug can be also used to stabilize mood — and another to dull the side effects of the other medications, although it is used mainly for schizophrenia. She felt better some days but deeply sad on others. Her senior yearbook photo shows her smiling broadly, “but I felt terrible that day,” said Ms. Smith, who is now 19 and attends a local community college. “I’ve gotten good at wearing a mask.” She had come to exemplify a medical practice common among her generation: the simultaneous use of multiple heavy-duty psychiatric drugs. Psychiatrists and other clinicians emphasize that psychiatric drugs, properly prescribed, can be vital in stabilizing adolescents and saving the lives of suicidal teens. But, these experts caution, such medications are too readily doled out, often as an easy alternative to therapy that families cannot afford or find, or aren’t interested in. © 2022 The New York Times Company

By Andrew Jacobs A small study on the therapeutic effects of using psychedelics to treat alcohol use disorder found that just two doses of psilocybin magic mushrooms paired with psychotherapy led to an 83 percent decline in heavy drinking among the participants. Those given a placebo reduced their alcohol intake by 51 percent. By the end of the eight-month trial, nearly half of those who received psilocybin had stopped drinking entirely compared with about a quarter of those given the placebo, according to the researchers. The study, published Wednesday in JAMA Psychiatry, is the latest in a cascade of new research exploring the benefits of mind-altering compounds to treat a range of mental health problems, from depression, anxiety and post-traumatic stress disorder to the existential dread experienced by the terminally ill. Although most psychedelics remain illegal under federal law, the Food and Drug Administration is weighing potential therapeutic uses for compounds like psilocybin, LSD and MDMA, the drug better known as Ecstasy. Dr. Michael Bogenschutz, director at NYU Langone Center for Psychedelic Medicine and the study’s lead investigator, said the findings offered hope for the nearly 15 million Americans who struggle with excessive drinking — roughly 5 percent of all adults. Excessive alcohol use kills an estimated 140,000 people each year. “These are exciting results,” Dr. Bogenschutz said. “Alcohol use disorder is a serious public health problem, and the effects of currently available treatments and medications tend to be small.” The double-blind randomized trial followed 93 participants for 32 weeks and divided them into two groups: One received psilocybin and the other a placebo in the form of antihistamine pills. The participants, all of whom struggled with excessive drinking, also took part in 12 therapy sessions that began several weeks before they received their first doses and continued for a month after the final dose. The psilocybin dosage was determined according to participants’ weight, and their heart rate and blood pressure were monitored during the eight-hour sessions. © 2022 The New York Times Company

By Andrew Jacobs Marijuana and hallucinogen use among young adults reached an all-time record last year after having leveled off during the first year of the coronavirus pandemic, according to federal survey data. The findings, part of the government’s annual survey of drug use among young Americans, also found that nicotine vaping and excessive alcohol consumption continued to climb in 2021 after a brief pause. Another worrying trend among young people, ages 19 to 30: mounting consumption of alcoholic beverages suffused with THC, the psychoactive ingredient in cannabis. But there were some bright spots in the survey. Cigarette smoking and opioid abuse among young adults dropped last year, a continuing trend that has heartened public health experts. Taken in its entirety, the report provides a mixed picture of substance use in the United States that experts say reflects a number of disparate trends affecting young Americans: the devastating mental health effects of the pandemic; the increased availability of legal marijuana; and the emerging therapeutic embrace of psychedelics to treat depression, post-traumatic stress disorder and other psychological problems. “Overall, the results are very concerning,” said Dr. Nora Volkow, director of the National Institute on Drug Abuse, which publishes the annual Monitoring the Future survey. “What they tell us is that the problem of substance abuse among young people has gotten worse in this country, and that the pandemic, with all its mental stressors and turmoil, has likely contributed to the rise.” The online survey of people ages 19 to 60 was conducted from April to October 2021. Substance use research experts said the mounting use of marijuana in young adults was especially notable. The survey found that 43 percent in the 19-30 age group had used cannabis 20 or more times over the previous month, up from 34 percent. In 2011, that figure was 29 percent. Daily marijuana consumption also jumped significantly, to 11 percent from 6 percent in 2011. © 2022 The New York Times Company

By Emma Yasinski In the years since a family member of mine started taking methadone, a drug that helps him avoid the excruciating withdrawal symptoms and intense cravings that come with an opioid use disorder, he’s attended the funerals of three of his closest friends with whom he used to use drugs. The number of acquaintances he’s lost is in the double digits. Methadone might have saved them — if only they could have picked it up from their local pharmacy. Like heroin or oxycodone, methadone stimulates the opioid receptors in the brain. The difference is that while heroin rapidly floods these receptors leading to an intense high, the effect of methadone is more gradual and long-lasting. At the appropriate dose, my family member (whom I’m not naming due to the continued stigma surrounding opioids) and other patients can get full days of relief from pain, withdrawal, and cravings, without the intoxication. But methadone is tightly regulated. Rather than pick it up from the local pharmacy, patients have to visit a specialized clinic — often daily — to get each individual dose. In March 2020, concerns about Covid-19 led the Substance Abuse and Mental Health Services Administration, or SAMHSA, to relax those restrictions. The agency announced that states could request an exception allowing clinics to offer a greater amount of take-home doses— up to 28 days — for patients the clinical team believed were stable and could safely handle the medication. Some clinics embraced the opportunity. In a multistate survey of 170 opioid treatment programs, about half followed the relaxed SAMHSA guidelines for newly enrolled or less stable patients. And two-thirds of the clinics surveyed offered their stable patients a full four weeks of take-home doses. The pandemic provided the natural experiment to demonstrate that loosening regulations on methadone in the U.S. was safe for both patients and communities. More than two years later, on July 13, researchers at the National Institute on Drug Abuse and the National Center for Injury Prevention and Control published some of the most powerful results of that experiment. While deadly overdoses involving opioids rose to staggering heights in the U.S. during the first year of the pandemic, the percentage of overdose deaths involving methadone decreased.

Adam Miller · CBC News · A new analysis of the cause of depression has seemingly upended what we know about this common condition and challenged the use of antidepressants. But it may also leave patients with more questions than answers as the science evolves. A systematic umbrella review of 17 studies published in Molecular Psychology on July 20 looked at the decades-old theory that depression is caused by low serotonin, and found there was "no consistent evidence" of "an association between serotonin and depression." The theory that depression is caused by a chemical imbalance in the brain has been around since the 1960s. But for years, many experts have doubted this, feeling it oversimplified a complex condition. "The serotonin theory is very old and has been very popular since the '90s, when the pharmaceutical industry started promoting it," said Dr. Joanna Moncrieff, a psychiatry professor at University College London and lead author of the study. "But since about 2005, probably a bit before then, there's been sort of rumours that actually the evidence isn't very strong, or it's inconsistent. Some studies are positive, some studies are negative, but no one's really got that evidence together anywhere." Moncrieff and her team set out to challenge the serotonin theory in a systematic review of available research. They also went a step further in their conclusion by suggesting that antidepressants are ineffective at treating depression — and have largely worked as a placebo. ©2022 CBC/Radio-Canada.

Martha Bebinger Approaching a van that distributes safe supplies for drug use in Greenfield, Mass., a man named Kyle noticed an alert about xylazine. "Xylazine?" he asked, sounding out the unfamiliar word. "Tell me more." A street-outreach team from Tapestry Health delivered what's becoming a routine warning. Xylazine is an animal tranquilizer. It's not approved for humans, but it's showing up in about half of the drug samples that Tapestry tests in the rolling hills of western Massachusetts. It's appearing mostly in the illegal fentanyl supply but also in cocaine. Kyle rocked backward on his heels at the mention of cocaine. He and his friends regularly use cocaine, but lately, they had suspected that something else was in the bag. "The past week, we've all been just racking our brains, like 'What is going on?'" he said. "Because if we cook it up and we smoke it, we're falling asleep after." Kyle's deep sleep might have been triggered by fentanyl too, but Kyle said one of his buddies used a test strip to check for the opioid and none was detected. Xylazine surged first in some areas of Puerto Rico and then in Philadelphia, where it was found in 91% of opioid samples last year, the most recent reporting period. Data from January to mid-June shows that xylazine was in 28% of drug samples tested by the Massachusetts Drug Supply Data Stream (MADDS), a state-funded network of community drug-checking and advisory groups that uses mass spectrometers to let people know what's in bags or pills purchased on the street. Some areas of the state, including western Massachusetts, are seeing xylazine in 50% to 75% of samples. In Greenfield, that's a big change from last year, when xylazine wasn't a concern. © 2022 npr
