This bill amends the penalties associated with the possession and use of psilocybin for individuals aged 18 and older. It introduces a new section, 318-B:2-f, to RSA 318-B, 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 is set to take effect on January 1, 2026, and is expected to have indeterminable fiscal impacts on state and local governments due to potential changes in judicial and correctional costs associated with the modified penalties. The bill does not anticipate generating revenue, and the financial implications for county and local expenditures remain uncertain. The legislative analysis indicates that the bill may influence prosecution, incarceration, probation, and parole costs, necessitating further evaluation of its impact on the judicial system.
