Not coincidentally, Senate Minority Leader Charles Schumer (D-N.Y.) plans to introduce legislation today to decriminalize marijuana, which is on the list of scheduled substances along with drugs like heroin.
The bill would let each state decide whether to allow the commercial sale of cannabis, ending the legal grey space that many marijuana businesses find themselves in.
Various polls show that there is support for legalizing cannabis throughout the U.S. According to a recent CBS News poll, six in ten Americans think it should be legalized. A Pew Research Center poll put the number at 61 percent in favor of legalization, with 70 percent support among millennials.
What would it take to decriminalize marijuana federally and how would states negotiate their laws with the federal government? And what are the attitudes of Americans towards legalization?
