An Act relative to removing criminal penalties for limited psilocybin possession

HD 188 removes criminal penalties for possessing up to one gram of psilocybin (magic mushrooms), replacing them with a $100 civil fine. It exempts specific groups including veterans, first responders, individuals with certain medical conditions, Indigenous ceremonial users, and those in clinical research. The civil fines collected will fund a new Psilocybin Fines Trust Fund, which will support community harm reduction services, public health education, and grants for qualifying organizations serving impacted communities. The bill also updates related laws to include psilocybin in possession limits for marijuana. It ensures these penalties don't affect student aid, housing, or professional licensing.
