Through research and publications, MPP strives to provide the information Americans need to make sensible decisions about marijuana policy.


The goal of this public education campaign is "to tell the truth about marijuana." The MPP ally recently closed its doors, but we think its site is worth keeping open, so we've moved it to our server. Enjoy exploring Change the Climate's cutting-edge ad campaigns and marijuana myth busting information.


Coming soon: Although currently under construction, soon you'll be able to choose one of our Research Centers to find related studies, briefing papers, court decisions, news articles, MPP reports, congressional testimony and more, divided by topic. Check back soon!
