Legal barriers to marijuana are falling all over the United States. Pot, tried by nearly half of all Americans at some point in their lives, is already legal in some form in 23 states, and four states allow recreational use. Last Friday, two House bills were filed that could end the federal prohibition of marijuana, including one which would remove marijuana from the Controlled Substances Act’s schedules and regulate it similarly to alcohol. And as of the early minutes of this morning, pot is legal in the District of Columbia.
