Trends in LSD use among US adults: 2015-2018.

Drug and Alcohol Dependence May 15, 2020 R. Yockey, Rebecca A. Vidourek, Keith A. King 111 citations

LSD use among US adults increased 56.4% between 2015 and 2018, based on a national survey of over 168,000 people. The largest proportional increases occurred among adults aged 26–34 (from 19.6% to 31.1%) and 35–49 (from 2.73% to 8.82%). Use also rose among people with a college degree or more (from 18.2% to 31.1%) and among bisexual individuals (from 11.2% to 13.0%). In contrast, LSD use decreased among multi-racial individuals, those with less than a high school education, and those who perceived great risk from drugs. These trends can inform prevention and harm reduction efforts.

Use of psilocybin (“mushrooms”) among US adults: 2015–2018

Journal of Psychedelic Studies February 4, 2021 R. Andrew Yockey, Keith A. King 64 citations

About 9.68% of US adults aged 18 and older have used psilocybin at some point in their lives, based on pooled 2015–2018 national survey data from over 168,000 people. Lifetime use varied by demographics, drug use history, and sexual identity; people identifying as bisexual reported higher rates of use. Nearly two-thirds of those who had ever used LSD, methamphetamine, or heroin also reported psilocybin use. These findings can guide harm reduction strategies and public health messaging.

“Go ask Alice, when she’s 10-feet tall”: Psychosocial correlates to lifetime LSD use among a national sample of US adults

Journal of Psychedelic Studies June 26, 2019 R. Andrew Yockey, Keith A. King, Rebecca A. Vidourek 18 citations

LSD use is increasing among US adults. An analysis of 2017 national survey data identified psychosocial factors linked to lifetime use. Being male, African American or Hispanic, using alcohol, ecstasy, marijuana, inhalants, cocaine, or cigarettes before age 21, having suicidal thoughts, and enjoying or seeking risky activities were all associated with higher likelihood of LSD use. The findings may help health professionals address this growing trend.
