From Prohibition to Progress: A Status Report on Marijuana Legalization

What We Know About Marijuana Legalization in Eight States and Washington, D.C.

On November 6, 2012, Colorado and Washington became the first two states – and first two places in the world – to legalize marijuana for adult use. Two years later Alaska, Oregon and Washington, D.C. followed suit. In 2016 voters in four additional states – California, Massachusetts, Maine and Nevada – also approved ballot measures legalizing marijuana. In January 2018, Vermont became the first state to legalize marijuana through a state legislature. More states are expected to legalize in the near future.

Evidence shows that marijuana legalization is working so far. States are saving money and protecting the public by comprehensively regulating marijuana for adult use.
