MPP also works for sensible cannabis policies at the state level, and our grassroots and lobbying campaigns have changed several laws. MPP provided the bulk of the funding, staff, and expertise to the 2012 Colorado initiative to legalize and regulate cannabis for adults 21 and older — which made the state the first place in history to legalize cannabis for adults and regulate it like alcohol. In 2014, MPP followed up with the successful campaign to legalize and regulate cannabis in Alaska. Then, in 2016, MPP spearheaded the legalization initiatives that voters enacted in Maine, Massachusetts, and Nevada. In 2018, MPP — working with local partners — led the successful initiatives to legalize cannabis in Michigan and medical cannabis in Utah. Most recently, MPP played an important role in the successful 2020 initiatives in Montana and South Dakota, working closely with the campaigns on the ground in each state.
