This bill amends the penalties associated with the possession and use of psilocybin for individuals aged 18 years and older. It introduces a new section, RSA 318-B:2-f, which outlines a tiered penalty system for offenses related to psilocybin. For a first offense, individuals will face a violation and a fine of up to $100. A second offense will result in a class B misdemeanor and a fine of up to $500, while a third offense will also be a class B misdemeanor with a fine of up to $1,000. For a fourth or subsequent offense, the penalties will revert to those specified in RSA 318-B:26. Additionally, individuals under 18 years of age will continue to face the penalties outlined in RSA 318-B:26.

The bill also specifies that it will take effect on January 1, 2026. The fiscal impact of the bill is indeterminable, as it may affect the judicial and correctional systems, potentially influencing costs related to prosecution, incarceration, probation, and parole for the state, counties, and local governments. The bill does not project any revenue changes and indicates that the expenditures related to its implementation are also indeterminable.
