Hallucinogens: Large Increases in Use Since 2015

New data show that nationwide hallucinogen use is growing faster than any other illicit substance. From 2015 to 2022, past-year hallucinogen use grew 81% – increasing from 4.7 million people in 2015 to 8.5 million people in 2022. While hallucinogens have not generally been a major focus of behavioral health or drug control policy, these trend data suggest that they may become a growing issue.
