Hawaii Medical Cannabis Guide

Hawaii was the first US state to legalise medical cannabis through its state legislature (rather than by ballot measure) in 2000. The programme has eight licensed dispensaries, limited by state law. Personal possession was decriminalised in 2019, but adult-use retail sales remain illegal.
