California lawmakers on Thursday narrowly approved a bill supported by veterans and criminal justice reform advocates to decriminalize the possession and personal use of a limited list of natural psychedelics, including “magic mushrooms.”

Gov. Gavin Newsom will now decide the fate of Senate Bill 58, which would remove criminal penalties for the possession and use of psilocybin and psilocin, the active ingredients in psychedelic mushrooms, mescaline and dimethyltryptamine, or DMT, known as ayahuasca. The bill also would require the California Health and Human Services Agency to study the therapeutic use of psychedelics and submit a report with its findings and recommendations to the Legislature.
