No link found between psychedelics and psychosis

    In large US survey, users of LSD and similar drugs were no more likely to have mental-health conditions than other respondents.

    Data from population surveys in the United States challenge public fears that psychedelic drugs such as LSD can lead to psychosis and other mental-health conditions and to increased risk of suicide, two studies have found.

    In the first study, clinical psychologists Pål-Ørjan Johansen of EmmaSofia, a non-profit advocacy group based in Oslo, and Teri Suzanne Krebs of the Norwegian University of Science and Technology in Trondheim, scoured data from the US National Survey on Drug Use and Health (NSDUH), an annual random sample of the general population, and analysed answers from more than 135,000 people who took part in surveys from 2008 to 2011.

    Of those, 14% described themselves as having used at any point in their lives any of the three ‘classic’ psychedelics: LSD, psilocybin (the active ingredient in so-called magic mushrooms) and mescaline (found in the peyote and San Pedro cacti). The researchers found that individuals in this group were not at increased risk of developing 11 indicators of mental-health problems such as schizophrenia, psychosis, depression, anxiety disorders and suicide attempts. Their paper appears in the March issue of the Journal of Psychopharmacology.

    The findings are likely to raise eyebrows. Fears that psychedelics can lead to psychosis date to the 1960s, with widespread reports of “acid casualties” in the mainstream news. But Krebs says that because psychotic disorders are relatively prevalent, affecting about one in 50 people, correlations can often be mistaken for causations. “Psychedelics are psychologically intense, and many people will blame anything that happens for the rest of their lives on a psychedelic experience.”

    The three substances Johansen and Krebs looked at all act through the brain’s serotonin 2A receptor. The authors did not include ketamine, PCP, MDMA, fly agaric mushrooms, DMT or other drugs that fall broadly into the category of hallucinogens, because they act on other receptors and have different modes of biochemical action. Ketamine and PCP, for example, act on the NMDA receptor and are both known to be addictive and to cause severe physical harms, such as damage to the bladder.

    “Absolutely, people can become addicted to drugs like ketamine or PCP, and the effects can be very destructive. We restricted our study to the ‘classic psychedelics’ to clarify the findings,” says Johansen.

    The 'acid casualty' myth
    “This study assures us that there were not widespread ‘acid casualties’ in the 1960s,” says Charles Grob, a paediatric psychiatrist at the University of California, Los Angeles. He has long has advocated the therapeutic use of psychedelics, such as administering psilocybin to treat anxiety in terminal-stage cancer. But he has concerns about Krebs and Johansen’s overall conclusions, he says, because individual cases of adverse effects use can and do occur.

    For example, people may develop hallucinogen persisting perception disorder (HPPD), a ‘trip’ that never seems to end, involving incessant distortions in the visual field, shimmering lights and coloured dots. “I’ve seen a number of people with these symptoms following a psychedelic experience, and it can be a very serious condition,” says Grob.

    Krebs and Johansen, however, point to studies that have found symptoms of HPPD in people who have never used psychedelics.

    The second of the new two studies, also published in the Journal of Psychopharmacology2, looked at 190,000 NSDUH respondents from 2008 to 2012. It also found that the classic psychedelics were not associated with adverse mental-health outcomes. In addition, it found that people who had used LSD and psilocybin had lower lifetime rates of suicidal thoughts and attempts.

    “We are not claiming that no individuals have ever been harmed by psychedelics,” says author Matthew Johnson, an associate professor in the Behavioral Pharmacology Research Unit at Johns Hopkins University in Baltimore, Maryland. “Anecdotes about acid casualties can be very powerful — but these instances are rare,” he says. At the population level, he says, the data suggest that the harms of psychedelics “have been overstated”.

    "Truth over fear"
    5/5, 5 out of 5, reviewed Dec 19, 2018
    I gave a good briefing on this article in means of what it gives to me.

    Basically we need this type of information, we need truth about substances not fear in order to give information to people about psychoactive substances.

    There is no reason to use scare tactics in regards to drugs because of the trust needed and lost to the masses when that is done.

      I couldnt agree more. I am an advocate of replacing the war on drugs by a system focussed on harm-reduction, education and supervision. I am convinced that this will save lives in the whole supply chain from production to end user.

    My experience with mushrooms (not amanita but psilocybin) was positive each time. The worse I went through was when my visuals started flooding my view and I had to leave the dark room I was in because of a panic/dread feeling. As soon as I left the room it went away.

    Considering I have whatever mental disorders I have been diagnosed with, I am scared of any psychedelic. LSD scares the hell out of me. I can’t take a fucking Xanax (for panic attacks) without worrying about how it will make me feel........grumble grumble

    This article is very assuring that if I were to use a psychedelic again (I had the chance on my birthday and declined out of fear of what could happengrumble grumble) that it might not be so bad.

    It is a crime against humanity to deprive many children and adults who suffer terribly, from these substances wether used im a clinical/therapeutical, religious, spiritual or recreative setting or for creative, spiritual and personal development, introspection. As long as you know what you are doing (set and setting, inform yourself: these are not recreational (feel-good) drugs but if you use them wisely, you can benefit from them. I am bipolar and have ahdh myself. I am every time anxious but feel in awe and victorious after the come on. I fell in love with LSD.

    And I decided to go unmedicated earlier this year.

    After reading an experiment of treating childhood schizophrenia with LSD and psilocybin (https://drugs-forum.com/ams/treatment-of-childhood-schizophrenia-utilizing-lsd-and-psilocybin.28673/) the question raises if it it can be used to treat schizophrenia in adults.

    In particular this example I found touching:
