Hallucinogen-related emergency department visits in California rose 54% from 2016 to 2022 (2260 to 3476 visits), while alcohol-related visits fell 20% and cannabis-related visits rose 15%. Hallucinogen-related hospitalizations increased 55% (2556 to 3965), compared with a 1% increase for both alcohol and cannabis. These trends were statistically different from those for alcohol and cannabis. The absolute numbers remain small, but the relative increase is large.
Thirty psychedelic researchers identified critical gaps in knowledge about harms from psychedelic use, including how to define those harms, predict them, and treat them effectively. They recommend better online information, peer support groups, affordable therapy, and psychiatric consultation for people experiencing post-psychedelic difficulties. The researchers also call for improved funding for a psychedelic safety net, suggesting that psychedelic philanthropists, investors, and companies commit 1% of their investment to support safety measures such as research and support services. The article outlines practical steps to make the field of psychedelic medicine safer.
