Cannabis legalization racked up a slew of victories in Tuesday's elections.

New Jersey, Arizona, South Dakota, and Montana voted to legalize cannabis for all adults over the age of 21. South Dakota also voted to create a medical-cannabis program, as did Mississippi. It will take time for legalization to take effect in each of the states.

Colorado and Washington broke ground in 2012 as the first US states to legalize recreational cannabis. Thirteen states and Washington, DC, have now joined them. Medical marijuana will be legal in 35 states, meaning a majority of Americans will have some form of access to legal marijuana.

Ballot initiatives have played a major role in the spread of legal cannabis, and 13 of the states that legalized recreational marijuana did so through referendums.
