Twenty-nine states and the District of Columbia currently have laws broadly legalizing cannabis in some form and the list of qualifying health conditions for medical cannabis in each state continues to grow.
Seven states and the District of Columbia have adopted the most expansive laws legalizing cannabis for recreational use. Most recently, California, Massachusetts, Maine and Nevada all passed measures in November legalizing recreational cannabis. California’s Prop. 64 measure allows adults 21 and older to possess up to one ounce of cannabis and grow up to six plants in their homes. Other tax and licensing provisions of the law will not take effect until January 2018.
Several legislatures in states recently passing legalization measures are debating regulatory proposals around the use and sale of cannabis. Massachusetts lawmakers were weighing bills earlier this year that would lower the amount residents can legally possess and place restrictions on retail stores.
A number of states have also decriminalized the possession of small amounts of cannabis. Some medical cannabis laws are broader than others, with types of medical conditions that allow for treatment varying from state to state. Several states (not shown on the map below) have passed narrow laws allowing residents to possess cannabis only if they suffer from certain rare medical illnesses.
Our map shows current state laws and recently-approved ballot measures legalizing cannabis for medical or recreational purposes. Final rules for recently-passed medical cannabis laws are pending in Arkansas, Florida and North Dakota.
