On 9 January 2018, U.S. Rep. Earl Blumenauer, a Democrat from Oregon, introduced a bill popularly termed the “Regulate Marijuana Like Alcohol Act.” The bill “would take marijuana off the federal controlled substances list and establish a nationally regulated industry overseen by the Bureau of Alcohol, Tobacco, Firearms and Explosives.”

The number assigned to this proposed legislation was H.R. 420, a number frequently referenced in cannabis culture. This number, steeped in legend and rumor, most commonly refers to a time to light up during the day (4:20), or as an informal marijuana holiday on April 20th (4/20).
