Psychedelics and psychosis: study reports no link

7 Mar

Here is the account in Nature. Here is the study abstract:

“A recent large population study of 130,000 adults in the United States failed to find evidence for a link between psychedelic use (lysergic acid diethylamide, psilocybin or mescaline) and mental health problems. Using a new data set consisting of 135,095 randomly selected United States adults, including 19,299 psychedelic users, we examine the associations between psychedelic use and mental health. After adjusting for sociodemographics, other drug use and childhood depression, we found no significant associations between lifetime use of psychedelics and increased likelihood of past year serious psychological distress, mental health treatment, suicidal thoughts, suicidal plans and suicide attempt, depression and anxiety. We failed to find evidence that psychedelic use is an independent risk factor for mental health problems. Psychedelics are not known to harm the brain or other body organs or to cause addiction or compulsive use; serious adverse events involving psychedelics are extremely rare. Overall, it is difficult to see how prohibition of psychedelics can be justified as a public health measure.”

    I am very skeptical about this study. Why would using a mind altering drug ever be acceptable just because the damage may not be permanent? The study scoffs at antidoal evidence, yet I do know of someone who did do permanent damage to himself by overdosing on LSD. According to the doctors at the time it was the cause of his mental illness. The damage happened many years ago, so I can’t say with absolute certainty that it was the cause of all his mental problems, but certainly overdosing on LSD did not help him.

    To quote the study: “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.

    Any drug can be distructive even classic psychedelics. Can you name a good use of these drugs? Why promote the use of these drugs?
