The study conducted by Johns Hopkins Medicine showed that U.S. adults with a history of using some non- addictive psychedelic drugs had reduced likelihood of psychological distress and suicidal thoughts, plans, and attempts.
In a national survey of over 190,000 U.S. adults, lifetime use of certain psychedelic drugs was associated with a 19 percent reduced likelihood of psychological distress within the past month, a 14 percent reduced likelihood of suicidal thinking within the past year, a 29 percent reduced likelihood of suicide planning within the past year and a 36 percent reduced likelihood of attempting suicide within the past year.
For the study, researchers pooled data from five years of results of the National Survey on Drug Use and Health (2008 to 2012) to evaluate the relationship between a history of using certain nonaddictive psychedelic drugs and psychological distress and suicidality. The annual survey, administered by the Substance Abuse and Mental Health Services Administration of the U.S. Department of Health and Human Services, estimates the prevalence of substance use and mental illness in the general U.S. civilian noninstitutionalized population. The study focused on respondents with a history of using nonaddictive psychedelic drugs, which interact with certain serotonin receptors in the brain.
Of 191,382 respondents, 27,235 reported lifetime use of one or more of these psychedelics, primarily psilocybin and LSD. Lifetime use was concentrated among 26- to 64-year-olds and was more common among men; non-Hispanic whites and Native Americans/Alaska Natives, those with greater education and income; individuals who were divorced, separated or who had never married; those with greater self-reported engagement in risky behavior; and those who reported lifetime illicit use of other substances. Among users of these psychedelic drugs, only 240 said they never tried any other illicit drug.
In addition, 12,657 respondents reported psychological distress within the past month, 10,445 reported suicidal thinking within the past year, 3,157 reported suicidal planning within the past year and 1,716 reported suicidal attempt within the past year.
Johnson said that their general societal impression of these drugs was that they made people go crazy or were associated with psychological harm, but their data pointed to the potential psychological benefits from these drugs.
The study is published in the Journal of Psychopharmacology.
