Colorado legalized medical marijuana in 2000 and recreational cannabis in 2012. This means simple possession, home cultivation, commercial farms, and retail sale of marijuana are legal. Unlicensed sale and processing remain illegal, and possession of a significant amount of cannabis can draw criminal charges.
