Missouri Cannabis History

More than twenty years after California became the first U.S. state to legalize medical marijuana, Missouri followed suit in 2018. Amendment 2 legalized consumption, cultivation, and sales of marijuana for medicinal purposes.

Previously, 2014’s HB 2338 legalized hemp-derived CBD oil to treat seizures, the growth of industrial hemp for research purposes, and established the Missouri Hemp Extract Registration Program (MHERP).
