MPP is working in Washington, D.C. to allow states to determine their own cannabis policies without federal interference, and is pushing for other federal reforms to advance equity and justice. For more information on our past and present work, visit our Federal Policy page, and take action to support our work.

MPP also works for sensible cannabis policies at the state level, and our grassroots and lobbying campaigns have changed dozens of laws. MPP played a leading role role in 14 of the 24 measures to legalize, regulate, and tax cannabis for adults 21 and older.

MPP spearheaded and / or was the top funder for successful ballot initiatives to legalize cannabis for adults in Colorado in 2012; Alaska in 2014; Maine, Massachusetts, and Nevada in 2016; Michigan in 2018; Montana in 2020, and Ohio in 2023. MPP’s team also played a leading role in the legislative campaigns that resulted in passing legalization in Vermont (2018), Illinois (2019), Connecticut (2021), Rhode Island (2022), and Delaware (2023.) MPP also played a leading role in legalization efforts in Maryland, where lawmakers referred legalization to voters, who approved it by a 2:1 margin in November 2022.

Legislatively, MPP and our allies are focusing on legalizing and regulating cannabis in Hawaii, Louisiana, New Hampshire, and Pennsylvania. MPP is also working with allies to enact medical cannabis-related bills in state legislatures in Kansas, North Carolina, and South Carolina, and is supporting decriminalization measures in several states.

In addition, MPP monitors and analyzes cannabis-related bills in all 50 states and the District of Columbia.
