Yes, weed is legal in DC as of February 26th, 2015. The legalization of marijuana in the District of Columbia was enacted through Initiative 71, which was approved by voters in November 2014. The initiative made it legal for adults 21 and over to possess up to two ounces of marijuana for personal use, grow up to six cannabis plants (with no more than three mature at a time), and transfer (gift) up to one ounce of marijuana. However, the sale of marijuana is still illegal under DC law.
