As detailed in a [new study]() published in the journal *Biological Psychiatry*, a team of Swiss researchers administered 20 participants, who were diagnosed with a life-threatening illness, and a further 22 participants with a mental disorder, significant amounts of lysergic acid diethylamide (LSD) — a drug more commonly used recreationally to induce a number of hallucinogenic effects — under the supervision of a trained therapist. The results, as measured by the use of scientifically-validated and widely used questionnaires, appear to have been much better than the researchers expected. "The response was surprisingly sustained," study co-author Matthias Liechti, a professor of clinical pharmacology at University Hospital Basel, Switzerland, [told *PsyPost*](). A [smaller, preceding pilot study]() found that LSD could reduce the symptoms of anxiety in those experiencing life-threatening illnesses. "Primarily, we wanted to confirm a pilot study on the effects of LSD in patients with anxiety and life-threatening illness," Liechti told *PsyPost*. "Secondly, we also wanted to explore therapeutic benefits in patients with an anxiety disorder such as general anxiety disorder and without the somatic illness." The [use of psychedelic drugs for therapeutic purposes]() is a rapidly growing field of research. Scientists are already investigating whether psilocybin, the hallucinogenic substance in magic mushrooms, could also be used to [treat depression](). "Furthermore, we wanted to use LSD instead of psilocybin, which is more commonly used in modern psychedelic research, to broaden the field," Liechti added. Participants of the study received either LSD or a placebo over three visits covering a 24-week period. The ones who received LSD were administered 200 micrograms, the [top end of the range]() for therapeutic purposes. "LSD produced strong reductions of anxiety, depression, and general psychiatric symptomatology compared with placebo in the first treatment period," the researchers write in their paper. "Effects were maximal 2 weeks after the second LSD session and sustained up to 16 weeks." But such a study comes with some inherent risks as well. The team observed nine "serious adverse events," six of which "occurred during the LSD period," and three of which "occurred during the placebo period," according to the paper. One patient even had to "kept overnight and discharged in the morning," as Liechti told *PsyPost*, but fortunately "experienced no further long-term symptoms." Then there's the fact that patients likely had no issues figuring out whether they were given LSD or a placebo, judging by whether they started tripping, which is a classic difficulty in studying psychedelic drugs in a clinical setting. "It remains to be shown whether blinding can be improved with these active placebo approaches and valid blinding remains a challenge in any trials that use psychedelics as well as in many other clinical trials," the team concludes in the paper. Despite the early successes, the widespread use of psychedelics for therapeutic purposes is still many years out. "Further, larger trials are needed to confirm these findings," reads the paper — and fortunately, that's not out of the question, given the upswell in interest. **READ MORE:** [LSD-assisted therapy induces rapid and lasting reductions in anxiety and depression symptoms, according to new research]() \[*PsyPost*\] **More on LSD:** *[Evidence Is Growing That LSD Improves Learning and Memory]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
