On Wednesday, one of America’s largest marijuana advocacy groups — the Marijuana Policy Project — released a list of who it thinks are the top 50 American individuals who have used cannabis. It identifies people who have achieved high-levels of success and influence, and uses factors like “power to influence cultural and social attitudes, political clout, individual wealth, and personal media profile” to choose who takes the cake.

To qualify for MPP’s list, individuals must (1) be alive, (2) be a U.S. citizen, and (3) have consumed marijuana at least once in their life according to either their own account or that of a legitimate source. They do not need to currently consume marijuana or support marijuana policy reform.
