Classic psychedelic use is associated with reduced psychological distress and suicidality in the United States adult population

This large survey study (analysis) (n=191.382 total, n=27.235) of US adults found that lifetime classic psychedelic use was associated with a significantly reduced odds of past month psychological distress, past year suicidal thinking, planning & attempt.

Abstract of Classic psychedelic use is associated with reduced psychological distress and suicidality in the United States adult population

“Mental health problems are endemic across the globe, and suicide, a strong corollary of poor mental health, is a leading cause of death. Classic psychedelic use may occasion lasting improvements in mental health, but the effects of classic psychedelic use on suicidality are unknown. We evaluated the relationships of classic psychedelic use with psychological distress and suicidality among over 190,000 USA adult respondents pooled from the last five available years of the National Survey on Drug Use and Health (2008–2012) while controlling for a range of covariates. Lifetime classic psychedelic use was associated with a significantly reduced odds of past month psychological distress (weighted odds ratio (OR)=0.81 (0.72–0.91)), past year suicidal thinking (weighted OR=0.86 (0.78–0.94)), past year suicidal planning (weighted OR=0.71 (0.54–0.94)), and past year suicide attempt (weighted OR=0.64 (0.46–0.89)), whereas lifetime illicit use of other drugs was largely associated with an increased likelihood of these outcomes. These findings indicate that classic psychedelics may hold promise in the prevention of suicide, supporting the view that classic psychedelics’ most highly restricted legal status should be reconsidered to facilitate scientific study, and suggesting that more extensive clinical research with classic psychedelics is warranted.”

Analysis of Classic psychedelic use is associated with reduced psychological distress and suicidality in the United States adult population

“Of the 191,382 respondents, 27,235 reported lifetime classic psychedelic use (13.6% weighted). Of these, 391 reported lifetime DMT use (0.1% weighted), 26 reported lifetime ayahuasca use (0.008% weighted), 18,152 reported lifetime LSD use (10.2% weighted), 4687 reported lifetime mescaline use (3.5% weighted), 3540 reported lifetime peyote or San Pedro use (2.4% weighted), and 20,274 reported lifetime psilocybin use (8.9% weighted). In addition, 12,657 of the respondents reported past month psychological distress (4.8% weighted), 10,445 reported past year suicidal thinking (3.8% weighted), 3157 reported past year suicidal planning (1.1% weighted), and 1716 reported past year suicide attempt (0.5% weighted).”

It’s interesting to note the very big differences in prevalence of use of these different psychedelics.

Summary of Classic psychedelic use is associated with reduced psychological distress and suicidality in the United States adult population

Almost half a billion people worldwide suffer from mental health problems, and suicide is among the deleterious consequences of poor mental health. Despite advances in mental health treatment over the past 60 years, suicide rates have not significantly declined.

Classic psychedelics, such as DMT, LSD, mescaline, and psilocybin, can occasion mystical-type experiences and have been used in sacramental healing contexts across cultures since time immemorial. Modern analysis suggests that classic psychedelics are among the least harmful of misused drugs, with limited dependence potential.

We examined the relationships between classic psychedelic use and psychological distress and suicidality among over 190,000 USA adult respondents pooled from the last five available years of the National Survey on Drug Use and Health. We found that classic psychedelic use was associated with a significantly reduced odds of these outcomes.
