LSD Shows Promise For Reducing Anxiety In Drugmaker's Midstage Study 56

An anonymous reader quotes a report from the Associated Press: LSD reduced symptoms of anxiety in a midstage study published Thursday, paving the way for additional testing and possible medical approval of a psychedelic drug that has been banned in the U.S. for more than a half century. The results from drugmaker Mindmed tested several doses of LSD in patients with moderate-to-severe generalized anxiety disorder, with the benefits lasting as long as three months. The company plans to conduct follow-up studies to confirm the results and then apply for Food and Drug Administration approval. [...]

For the study, researchers measured anxiety symptoms in nearly 200 patients who randomly received one of four doses of LSD or a placebo. The main aim was to find the optimal dose of the drug, which can cause intense visual hallucinations and occasionally feelings of panic or paranoia. At four weeks, patients receiving the two highest doses had significantly lower anxiety scores than those who received placebo or lower doses. After 12 weeks, 65% of patients taking the most effective LSD dose -- 100 micrograms -- continued to show benefits and nearly 50% were deemed to be in remission. The most common side effects included hallucinations, nausea and headaches.

Patients who got dummy pills also improved -- a common phenomenon in psychedelic and psychiatric studies -- but their changes were less than half the size those getting the real drug. The research was not immune to problems seen in similar studies. Most patients were able to correctly guess whether they'd received LSD or a dummy pill, undercutting the "blinded" approach that's considered critical to objectively establishing the benefits of a new medicine. In addition, a significant portion of patients in both the placebo and treatment groups dropped out early, narrowing the final data set. It also wasn't clear how long patients might continue to benefit.
If the two trials are successful, Mindmed will submit them for FDA approval.

"It's possible that some people may need retreatment," said Dr. Maurizio Fava of Mass General Brigham Hospital, the study's lead author and an adviser to Mindmed. "How many retreatments, we don't know yet, but the long-lasting effect is quite significant."

The study has been published in the Journal of the American Medical Association.

What that does mean is that if your anxious, acid will make you turbo anxious, aka a 'bad trip'. (I *do not* recomend acid to folks with anxiety disorders, at least now without a babysitter with a bottle of valium to cancel the anxiety).

        Then again everyone reacts a bit differently. Acids a great time, but its not without a risk of a terrible time.

      Surprised to see it an actual LSD. Most of the research i'd heard about is on psilocybin (magic mushrooms).

      An amusing anecdote in some podcast (some pragmatic dharma one where these kinds of researchers tend to show up sometimes ) was that psilocybin research is easier to do since the whole trip is 4-6 hours so it can fit into one shift for the people running studies whereas LSD tends to be 10-12 hours which requires multiple shifts and just overall is harder on the researchers.

They aren't solving people's problems. Lost psychotechnologies... dude we've never been more medicated, there's literally a pill for everything.

      The entire premise of your thought process is that there is no chemical problems. You assumed that all the problems people experienced were external, none were internal. Then you concluded that drugs will not help, you need to fix the environment.

      I am sure that there are a lot of people that fit your definition. People that have no real genetic issues but are simply in a poor environment. But you have not met everyone.

      As someone who's sister is clearly obsessive compulsive and whose niece is obviously manic depressive, I can assure you that not all problems are external. Some do not depend on the environment.

      Humans have decreased evolutionary deaths for thousands of years. We have had mutations and faults develop in our genetic code. These people may not be the fittest, but they deserve the right to live a normal life.

      Some people have real, actual chemical problems that cannot be solved by fixing the environment. They need pharmeceuticals not to feel good, but just to stop feeling like there are still germs on their hands after washing them 3 times. Some people need chemicals to not go from being lottery winner happy to suicidal between two different college classes.

      Just because you personally (and perhaps your friends and family) are not helped by drugs, does not mean that no one else will be.

      I am not an expert. I do not know if LSD is actually medically helpful or just fun. But I trust the experts to have a better opinion than mine - or yours. They base their knowledge not on the average human but on the extremes that they have studied.

As an adult you'll learn that high school drama comes from being surrounded by immature people, and when you have a workplace like that, it's not you it's them. Anxiety from "fitting in" an immature, toxic workplace? You'll have adult tools to deal with that. Like fuck you I quit.

  • Has federal law become something of a pirate code? More like guidelines than actual rules?

    LSD is considered a prohibited substance in federal law as it has no recognized medical use. Just possessing it is considered a felony, unless you have a license from the DEA. I assume the DEA license is to allow for police officers to confiscate these drugs and not be considered felons themselves. Is this also a license (in more than one sense of the word) to give the drug to people to see what it could do to them

    It seems pretty plausible that sub-recreational doses of psychedelics could reduce anxiety, but we have to be mindful that anxiety evolved in our species for a reason. Like inflammation, it’s a natural and critically important protective process that gets out of control in modern lifestyles. It’s unpleasant but pharmaceutically banishing it could leave patients vulnerable.

    One of the biggest risks psychedelic therapy will expose patients to are the therapists overseeing their treatment. Psychedelic therapy has an appalling track record of abuse by therapists, including both sexual and economic exploitation. Advocates for psychedelic therapy claim it will “open you up” and I think they’re absolutely correct. But there are other ways to say “open you up” that mean the same thing but set off alarm bells: becoming more suggestible and compliant for example. If the therapist uses psychedelics himself he may have “opened himself up” to some bad ideas about therapist-patient boundaries.

    Likewise people microdosing to enhance creativity should exercise caution. Psychedelics absolutely can in some instances unlock creativity by turning down excessive self criticism, but those criitical facilities play an essential role in the parts of the creative process that come after coming up with out of the box ideas. Self reports of microdosing effectiveness should be taken cautiously, due to their potential negative impact on metacognition. Those might be like the drunk who feels more confident driving after a few drinks.

    No doubt these drugs have tremendous potential to treat extreme crippling anxiety. They probably even have nootropic potential. But their beneficial effect s come by suppressing natural mental processes that serve important purposes, and the promising results we have come from self reports or clinical reports from advocate researchers. I’ve been following this because I’ve been interested in experimenting with psychedelics for years, but what I have learned has convinced me to hold off until there is evidence and protocols for safe use that would persuade a skeptic.

  • Not into psyches but have done acid when I was younger and prefer to do 250mg of MDMA/MDA for fun but a few years back did some experimenting with shooms. I'd take about .5g and wait about 45min when I start to feel a tiny weed like buzz then take another .5g. You don't trip but get a weed like high with out the lethargic feel of weed and no munches. Next two days after where super relaxing and way less anxiety.

    I took a lot of psychedelics when I was younger -- LSD, psilocybin, mescaline, DMT. Then none for a few decades. These days I microdose on psilocybin.

    To me, psychedlics are like watching a travelogue about a beautiful tropical island. It's a lovely vision, but it doesn't take you there -- you still have to do the traveling yourself. But it does plant the idea that such a place exists, which can be a great comfort, and inspire further efforts to get thete on your own.
