Representatives Tom Garrett (R-VA) and Tulsi Gabbard (D-HI) have introduced bipartisan legislation in Congress to exclude marijuana from the federal Controlled Substances Act. This provides states with the exclusive authority to standardize the plant as best as they can. The “Ending Marijuana Prohibition Act of 2017” eliminates the cannabis plant from the CSA so that it is no longer listed under federal law. This legislation gives states the authority and flexibility to establish their own marijuana policies free from federal interference. Individual states are more than capable of choosing their own cannabis policies, Rep. Garrett explained in a prepared statement.
