Among people attending electronic dance music parties in New York City nightclubs and festivals, self-reported use of several drugs changed from 2017 to 2022. Past-year and past-month use of psilocybin mushrooms, ketamine, poppers, synthetic cathinones, and novel psychedelics increased, while past-year heroin use and past-month cocaine, novel stimulant, and nonmedical benzodiazepine use decreased. After the COVID-19 pandemic, the odds of using mushrooms, poppers, and 2C series drugs rose, whereas the odds of using cocaine, ecstasy, heroin, methamphetamine, novel stimulants, and prescription opioids nonmedically fell. These trends in a sentinel population can inform public health surveillance.

Seizures of psilocybin mushrooms by U.S. law enforcement rose sharply between 2017 and 2022, suggesting increasing availability. The number of seizures grew from 402 in 2017 to 1,396 in 2022, a 368.9% increase, with the Midwest accounting for the most seizures (36.0%) and the West next (33.5%). The total weight seized rose from 226.0 kg to 844.0 kg, a 2,749.7% increase; the West had the greatest total weight (1,864.2 kg, 42.6%) followed by the South (1,831.9 kg, 41.8%). Significant increases occurred in all four U.S. regions. The authors call for more prevention and harm reduction education.

About 1 in 15 young adults in the United States reported microdosing hallucinogens in the past year, with 73% of those who used hallucinogens engaging in microdosing. Microdosing was strongly linked to other substance use: among microdosers, 72% reported 10 or more occasions of past-year alcohol use and 86% reported 3 or more occasions of past-year cannabis use. Odds ratios for other substance use among microdosers ranged from 2.53 for past-month cigarette use to 37.73 for heavy cannabis use. Few demographic differences emerged, though Black respondents were less likely to microdose than White respondents.
