According to national polls — including Pew, Gallup, and CNN — a majority of Americans now support making marijuana legal for adults’ use. Voters in eight states and Washington, D.C. have approved measures legalizing marijuana for individuals over 21, and the eight states — Alaska, California, Colorado, Maine, Massachusetts, Nevada, Oregon, and Washington — approved taking marijuana production and sales off the criminal market and regulating and taxing them.

Below you will find information about those laws and how they are working, along with materials to make the case for allowing adults to use a substance that is safer than alcohol.

Note: Most of the below documents have not yet been updated to reflect voters’ enactment of four laws legalizing and regulating adult-use marijuana on November 8, 2016. We will be updating them soon.
