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.
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.
