Eight U.S. states and the District of Columbia have now legalized marijuana for adult recreational use, but not all pot laws are created equal.
Colorado and Washington were the first two states to legalize the drug for adult use in 2012. Oregon, Alaska and the District of Columbia came next, passing measures to legalize recreational marijuana use in 2014. Most recently, California, Nevada, Massachusetts and Maine all passed voter initiatives in the 2016 general elections to legalize cannabis for adult recreational use.
See the following gallery for important details about the laws in each state where marijuana has been legalized for adult use.

While not technically a state, District of Columbia voters passed Initiative 71 to legalize adult marijuana use in 2014. The measure permits adults 21 and older to possess and use up to two ounces of marijuana, and cultivate up to three marijuana plants at home.

However, adults may grow their own cannabis and gift up to one ounce of the drug to other adults in the District. (Photo credit: Alex Wong/Getty Images)
