Thirty states and the District of Columbia currently have laws broadly legalizing marijuana in some form. Eight states and the District of Columbia have adopted the most expansive laws legalizing marijuana for recreational use. Most recently, sales of recreational-use marijuana in California kicked off on Jan. 1. In Massachusetts, retail sales of cannabis are expected to start later this year in July. Voters in Maine similarly approved a ballot measure legalizing marijuana in 2016. The state, however, has not yet adopted rules for licensed marijuana growers or retailers, nor has it begun accepting licenses.
The vast majority of states allow for limited use of medical marijuana under certain circumstances. Some medical marijuana laws are broader than others, with types of medical conditions that allow for treatment varying from state to state. Louisiana, West Virginia and a few other states allow only for cannabis-infused products, such as oils or pills. Other states have passed narrow laws allowing residents to possess cannabis only if they suffer from select rare medical illnesses. A number of states have also decriminalized the possession of small amounts of marijuana.
