AN ACT CONCERNING A STUDY CONCERNING DRIVING UNDER THE INFLUENCE OF CANNABIS OR PSILOCYBIN.

HB 7258 requires Connecticut's Department of Emergency Services and Public Protection to study whether setting specific blood THC (cannabis) and psilocybin levels would allow for automatic legal presumption of driving under the influence, similar to current blood alcohol content limits for alcohol. The study must examine approaches used in Colorado, Illinois, Montana, Nevada, Ohio, and Washington, and report findings with recommendations by February 1, 2026. This bill does not create new laws or penalties but prepares the state for potential future policy decisions regarding cannabis and psilocybin impairment. It directly affects future legislative and regulatory decisions about DUI standards, not current drivers. The study has no anticipated fiscal impact as it uses existing department expertise.
