Senate Bill 2486, known as the "Freedom to Farm Act," amends Tennessee law to allow registered adults to cultivate, possess, and use marijuana under specific conditions. Adults aged 21 and older can cultivate up to 15 marijuana plants, with a maximum of 5 being mature, in a private area of their residence that is secured and not visible to the public. The bill outlines the definitions of various terms related to marijuana, including "cultivate," "mature plant," and "marijuana trim." It also establishes a registration process through the Department of Agriculture, which requires a $100 fee and is valid for three years. Registered adults must ensure that minors do not have access to areas where marijuana is cultivated or stored.

Additionally, the bill stipulates that the registration fee will be used for administering the registration process, with any surplus revenue directed to a farmers' market support program. This program will provide grants to support farmers' markets across the state, with guidelines established by the commissioner of agriculture. The act will take effect upon becoming law for the rule promulgation, while other provisions will be effective starting January 1, 2027.
