Last week, a bipartisan group of 21 state attorneys general sent a letter to congressional leaders imploring Congress to pass marijuana reform legislation. Specifically, the letter exhorts Congress to pass the proposed Strengthening the Tenth Amendment Through Entrusting States Act (the “STATES Act”), or similar legislation, that would “allow each State and territory to determine, for itself, the best approach to marijuana legalization within its borders, while at the same time creating protections to ensure that such regulation does not impose negative externalities on those states and territories that choose other approaches.”
