Marijuana is already legal in four states and DC, and 23 states have medical marijuana. Now, a pair of federal legalization bills are in the hopper. Two congressmen from two states where marijuana is already legal under state law today filed two separate bills to legalize marijuana at the federal level. Rep. Jared Polis (D-CO) introduced a bill that would allow states to legalize marijuana without fear of federal intervention, while Rep. Earl Blumenauer (D-OR) introduced a bill that would tax marijuana at the federal level, in addition to any state taxes. The bills were not yet available on congressional web sites as of this afternoon.
