State-level cannabis legalization

State-level cannabis legalization means that individual U.S. states have chosen to allow the use, possession, and sale of cannabis within their borders, even though it remains illegal under federal law. Each state sets its own rules regarding how cannabis is regulated, the amount residents can possess, and whether commercial sales are permitted. Legislation varies widely, with some states legalizing recreational use for adults, others only permitting medical use, and some still banning it entirely. This decentralized approach reflects differing public policies and attitudes toward cannabis across the country.
