Yet another study shows the potential efficacy of psychedelics in treating addiction.
- MDMA could help alcoholics break their addiction (and not relapse) suggests a new study in the UK.
- Ketamine became the first FDA-sanctioned psychedelic for use in treating depression earlier this year.
- The Multidisciplinary Association for Psychedelic Studies (MAPS) organization hopes to have legally prescribed MDMA on the shelves by 2021.
Is MDMA psychiatry’s antibiotic? | Ben Sessa | TEDxUniversityofBristol<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="9ea769e850d777ed502d3cdc6dbd5cda"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/UygZnBTWW0M?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>All of these substances have been used recently in addiction treatment. As Pollan notes, MDMA specifically was being used to treat alcoholism back in the fifties and sixties, before sanctioned studies were commissioned. It was only due to Nixon's <a href="https://harpers.org/archive/2016/04/legalize-it-all/" target="_blank" rel="noopener noreferrer">racist profiling</a> that these class of drugs were deemed Schedule 1. </p><p>Now that the <a href="https://casereports.bmj.com/content/12/7/e230109" target="_blank">first study</a> on MDMA's role in treating alcoholism is complete, it turns out that the longstanding anecdotal evidence might bear fruit. Led by Ben Sessa, a senior research fellow at Imperial College London, the team studied seven volunteers during an eight-week MDMA-assisted psychotherapy course to see if it would help curb their alcoholism. This preliminary paper focuses on four volunteers who have completed the course. </p><p>While this is an extremely small sample size, it does open the door for further studies, which is the general aim of such research. Given the tenuous nature of psychedelic research due to the drugs' illegality, governments (and the public) have to be brought in slowly, even as advocates can vouch for their value. </p><p>Simply put, we need better interventions. As the team notes, 6 percent of men and 2 percent of women in England are alcohol-dependent; a quarter of the population has an abusive relationship to alcohol. As a depressant, alcohol also heavily influences mental and emotional health. It is often a chicken-and-egg scenario in regards to mental health and alcoholism, but one thing is certain: drinking doesn't help.</p>

Current treatment methods are insubstantial. Relapse rates there are 60 percent after one year, jumping to 80 percent after three years.</p><p>For this study, the patients received ten therapeutic sessions. Eight were non-drug psychotherapy sessions. The other two, administered during weeks three and six, included 125 mg doses of MDMA (with an optional 62.5 mg "booster" dose after two hours). </p><p>None of the volunteers experienced adverse effects during or after the course, nor did they return to drinking. Importantly, none felt any craving for MDMA after the study's conclusion. As one participant commented, the drug itself was more a mediator than anything: </p><p style="margin-left: 20px;">It's not about the drinking, the MDMA healed me inside and the drinking looks after itself … I'm seeing things anew, nature for the first time … I'm in control of my decisions, I've got control back … Life is just good!</p><p>Comments from other participants include the feeling of a "weight being lifted off my shoulders" and "being under MDMA was beautiful. It showed me the real me; the me without alcohol." </p><p>Now the team is calling for twenty volunteers with alcohol dependency in order to conduct another study. Separating the actual efficacy of psychedelics and its sordid legal status and past fear-mongering will take time, but hopefully not too much. Earlier this year, ketamine became the first <a href="https://www.fda.gov/news-events/press-announcements/fda-approves-new-nasal-spray-medication-treatment-resistant-depression-available-only-certified" target="_blank">FDA-approved psychedelic</a> to be legally prescribed. </p><p>The Multidisciplinary Association for Psychedelic Studies (MAPS) has trained its sights on <a href="https://maps.org/news/media/6488-popular-science-mdma-could-be-on-the-market-legally-by-2021" target="_blank">legal MDMA</a> by 2021. Given the emerging science on the topic, such a goal is within reach. That's good news for addicts that feel their time is running out. </p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a> and <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a>.</em></p>
A new report from the World Health Organization outlines some sobering statistics on the global toll of alcohol consumption.
- The report indicates that the 'harmful use' of alcohol leads to about six deaths per minute.
- Poorer countries tend to see higher rates of alcohol-related deaths and injuries.
- The WHO suggests deaths can be prevented through policies that restrict pricing, marketing, consumption and other factors.
Governments aren't implementing effective policies<p>WHO alcohol-control expert, Dr. Vladimir Poznyak, told <em><a href="https://www.theguardian.com/society/2018/sep/21/5-of-all-deaths-due-to-alcohol-who-says" target="_blank">The Guardian</a></em> that the health burden of alcohol was "unacceptably large."</p><p>"Unfortunately, the implementation of the most effective policy options is lagging behind the magnitude of the problems," he said. "Governments need to do more to meet the global targets and to reduce the burden of alcohol on societies; this is clear, and this action is either absent or not sufficient in most of the countries of the world."</p><p><img src="https://assets.rbl.ms/18654218/980x.jpg">Although the levels of harm caused by alcohol largely depend on factors both individual (age, socioeconomic status, gender) and societal (culture, alcohol laws), the report suggests that governments can curb alcohol-related deaths and injuries by:<br></p><ul><li>regulating the marketing of alcoholic beverages (in particular to younger people)</li><li>regulating and restricting the availability of alcohol</li><li>enacting appropriate drink-driving policies</li><li>reducing demand through taxation and pricing mechanisms</li><li>raising awareness of public health problems caused by harmful use of alcohol and ensuring support for effective alcohol policies</li><li>providing accessible and affordable treatment for people with alcohol-use disorders, and</li><li>implementing screening and brief interventions programmes for hazardous and harmful drinking in health services.</li></ul><p>"Now the task we share is to help countries put in place policies that make a real and measurable difference in people's lives," wrote Dr. Tedros Adhanom Ghebreyesus, the director-general of the WHO. "We have no time to waste; it is time to deliver on alcohol control."</p><p><img src="https://assets.rbl.ms/18654228/980x.jpg">The WHO report comes in the wake of a recent study, <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(18)31310-2/fulltext" target="_blank">published by</a><em><a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(18)31310-2/fulltext" target="_blank"> The Lancet</a>, </em>in August, that made headlines primarily for suggesting that the "safest level of drinking is none."<span></span></p><p>"Alcohol poses dire ramifications for future population health in the absence of policy action today. Our results indicate that alcohol use and its harmful effects on health could become a growing challenge as countries become more developed, and enacting or maintaining strong alcohol control policies will be vital," Emmanuela Gakidou, the report's senior author, told <em><a href="https://www.theguardian.com/society/2018/aug/23/no-healthy-level-of-alcohol-consumption-says-major-study" target="_blank">The Guardian</a>.</em></p>
Explore how alcohol affects your brain, from the first sip at the bar to life-long drinking habits.
- Alcohol is the world's most popular drug and has been a part of human culture for at least 9,000 years.
- Alcohol's effects on the brain range from temporarily limiting mental activity to sustained brain damage, depending on levels consumed and frequency of use.
- Understanding how alcohol affects your brain can help you determine what drinking habits are best for you.
Alcohol inbound<p>To get to the brain, alcohol must first be <a href="https://sites.duke.edu/apep/module-1-gender-matters/content/content-how-is-alcohol-absorbed-into-the-body/" target="_blank">absorbed into your body</a> through the GI tract. Most of the booze will be sopped up by your small intestines, where epithelial cells send it into the bloodstream. If you are drinking on an empty stomach, the alcohol beelines to the small intestine, and you'll feel its effects wash over you quite suddenly. </p><p>But if you enjoyed some pub grub with your drink, you'll notice the effects take longer to hit you. That's because your pyloric sphincter is closed to allow the stomach to digest the food. While your stomach absorbs some of the alcohol, it can't manage the job as effectively as your intestines.</p><p>Once in the bloodstream, the alcohol moves throughout your body. Your liver begins metabolizing what alcohol it can, but it can only manage so much at a time. On average it can handle <a href="https://www.brown.edu/campus-life/health/services/promotion/alcohol-other-drugs-alcohol/alcohol-and-your-body" target="_blank">one standard drink per hour</a>, but this rate is highly dependent on you as an individual. Some people process their alcohol faster, others slower. </p><p>For the record, the United States health organizations measure <a href="https://www.niaaa.nih.gov/alcohol-health/overview-alcohol-consumption/what-standard-drink" target="_blank">one standard drink</a> as 1.5 ounces of distilled spirits (at roughly 40 percent alcohol by volume, or ABV), 5 ounces of wine (at roughly 12 percent ABV), and 12 ounces of beer (at roughly 5 percent ABV). </p><p>Since you are drinking out, you'll need to pay attention to how much you've consumed in standard measurements. If you ordered a pint of your favorite IPA, for example, you probably consumed 16 ounces of beer at 7.5 percent ABV. You ordered one drink, but your liver is handling closer to two standard drinks.</p><p>But hey, it's the weekend, and you decide to belly up to the bar and order another round.</p><p>At this point, you're consuming alcohol faster than your liver can metabolize it, and the excess is accumulating in your bloodstream, increasing your blood alcohol concentration (or BAC). As the alcohol rides your bloodstream, it eventually makes its way to your brain, where it passes the blood-brain barrier and begins interacting with your neurons.</p>

This is why it is known as a "depressant" — not because it makes you feel dispirited but because it reduces, or depresses, mental processes (compared to stimulants like caffeine that increase them). It manages this feat by tweaking with your brain signals. </p><p>Put simply, your nervous system relies on two types of signals: <a href="https://knowingneurons.com/2017/01/25/excitation-inhibition/" target="_blank">excitation and inhibition</a>. Think of them as your personal binary code. An excitatory signal tells a neuron to fire up; an inhibitory signal tells a neuron to stay sedate. Chemical messengers called neurotransmitters are responsible for these signals. <a href="https://www.scripps.edu/newsandviews/e_20020225/koob2.html" target="_blank">Glutamate and GABA</a> are the primary neurotransmitters for excitatory and inhibitory signals, respectively.</p><p>As you're enjoying your second drink, the alcohol is hindering your glutamate neurotransmitters while pumping up the GABA. Basically, it's telling your brain to chill out, and you perceive this mental inactivity as a drowsy, easygoing relaxation.</p><p>The alcohol is also increasing your brain's output of dopamine, another neurotransmitter that serves many functions, one of which is to control <a href="https://www.psychologytoday.com/us/basics/dopamine" target="_blank">your brain's reward center</a>. A sensation or experience that releases dopamine tells your brain, "Hey, this is going to feel good. Remember this experience because we'll want do this again sometime." </p><p>Dopamine is why we <a href="https://www.psychologytoday.com/us/blog/women-who-stray/201701/no-dopamine-is-not-addictive" target="_blank">experience drinking as fulfilling</a> and also why it can prove habit forming. <a href="https://www.sciencedaily.com/releases/2018/05/180523133315.htm" target="_blank">One study showed</a> that people with a family history of alcohol abuse release more dopamine than nondrinkers simply in expectation of a quaff.</p><p>At this point the chemical pickling process has intensified, and your mental inactivity starts to affect the various structures of your brain. As these brain structures switch from active to less active, you feel a <a href="http://sciencenetlinks.com/student-teacher-sheets/alcohol-and-your-brain/" target="_blank">variety of different effects</a>. </p><p>Your prefrontal cortex, for example, is your mind's executive and plays key roles in decision-making, self-management, and social behavior. As this region's activities slow down, you'll find you are more socially adventurous but also less cautious and prone to impulsive decisions.</p><p>Alcohol impairs your cerebellum, which <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4492805/" target="_blank">regulates balance and motor functions</a>. The more you drink the more you must concentrate to perform motor functions as basic as walking. A cock-eyed cerebellum also stifles your reaction time and is the reason why drinking and driving is so dangerous.</p><p>Then there's the hippocampus, the brain's hard drive. Even small amounts of alcohol can make memories slippery to hold on to. Drink enough and you'll find large portions of the evening's events completely wiped.</p>
Two (or more) drinks over the line<p>Depending on how much you drink, you can end up anywhere from squiffy to chemically inconvenienced to full-on drunk. But these are only the short-term effects. Alcohol can continue to alter your mind well beyond your morning hangover. </p><p>The brain is an incredibly adaptive organ, so the more often you drink the better it learns to compensate for alcohol's effects. This is why long-time drinkers have to drink more to maintain the same buzz. Drink heavily enough for long enough, and your brain's compensation will shift into normalcy, resulting in <a href="https://pubs.niaaa.nih.gov/publications/aa77/aa77.htm" target="_blank">alcohol dependence</a>. So, the more often you drink the more severely alcohol changes your brain.</p><p>Light drinking can be part of a healthy lifestyle and may even confer some health benefits. <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1002585" target="_blank">One study</a> found that light drinkers — those who consume less than three drinks per week — have a lower risk of cancer than moderate to heavy drinkers and even nondrinkers. Of course, the researchers warn that the "evidence should not be taken to support a protective effect of light drinking," so teetotalers needn't get their drink on just to mitigate their risk of cancer.</p><p>Moderate drinking — one drink a day for women, two for men — can also be part of a healthy lifestyle, but some research has suggested that even this rate of consumption can have ill health effects. One study found that moderate drinkers were more likely to develop <a href="https://www.health.harvard.edu/blog/this-is-your-brain-on-alcohol-2017071412000" target="_blank">hippocampal atrophy</a>.</p><p><a href="https://www.niaaa.nih.gov/alcohol-health/overview-alcohol-consumption/moderate-binge-drinking" target="_blank">Heavy drinking</a>, on the other hand, is undeniably harmful to your body and brain. Such levels of consumption can <a href="https://americanaddictioncenters.org/alcoholism-treatment/mental-effects/" target="_blank">impact your cognitive abilities</a> and lead to diminished gray matter, memory loss, loss of visuospatial abilities, and Wernicke-Korsakoff syndrome. Heavy drinking quite literally <a href="https://www.aan.com/PressRoom/Home/PressRelease/475" target="_blank">shrinks your brain</a>.</p>
Talk with your doctor<p>It's worth pointing out that our little thought experiment provides a general overview of how alcohol affects the brain. As with any drug, many factors influence how things shake out, such as a person's age, gender, genetic background, drinking history, and even level of education. Lifestyle choices such as whether you smoke or get enough exercise will also play in.f</p><p><a href="https://pubs.niaaa.nih.gov/publications/aa63/aa63.htm" target="_blank">Studies have suggested</a>, for example, that women who are heavy drinkers are more vulnerable than men at developing cirrhosis, nerve damage, and brain damage — even if they engage in such levels of consumption for fewer years.</p><p>If you choose to drink, the best way to determine what habits are best for you is to speak openly and honestly with your physician.</p>
A new study suggests that older couples may help their marriages by drinking together.
Almost half the wine consumed in the U.S is consumed by millennials, according to recent research. In 2015, the 79 million Americans ages 21 to 38 drank 159.6 million cases of wine. As a relaxant and social lubricant, it’s obviously a pretty popular way to go, and that’s just wine. As young people couple off, alcohol can work for and against the relationship, depending on the amount of alcohol consumed and whether or not both partners are drinking similarly. But what happens over time to couples? Baby boomers are finding out, and so did a new study published in the Journals of Gerontology.
There's a trillion-dollar underground economy hiding in plain sight, says Steven Kotler, and it can be measured in dopamine.
What really fuels the economy? It’s not trade, free spending, or good old-fashioned elbow grease – it’s something much smaller and harder to see: dopamine. Along with high-performance expert Jamie Wheal, Steven Kotler has spent the last four years interviewing and researching trailblazers like Elon Musk, Eric Schmidt, Amy Cuddy, and institutions like Nike's innovation team, the Navy SEALs, and the United Nations' Headquarters. What did he find? That these bright people and teams are using altered states of consciousness – like ‘flow’ – to boost their inspiration, ability, and impact. Winning feels good, as does reward. It all boils down to dopamine. Many of us may not be consciously aware of the the neurochemical, altered-state highs we seek on a daily basis. Kotler runs through three ways we chase dopamine, and questions the ethics of these unchecked habits. For example, when you check your phone for a text, the uncertainty or "magic of maybe" in what the text might deliver results in a 400% spike in dopamine – roughly the same amount of dopamine as a person gets from cocaine. "We’re essentially putting highly addictive drugs into the hands of kids before they have any natural defenses against them," says Kotler. Steven Kotler's and Jamie Wheal's book is Stealing Fire: How Silicon Valley, the Navy SEALs, and Maverick Scientists Are Revolutionizing the Way We Live and Work.
