There's one topic almost every 2020 Democratic presidential candidate agrees on: removing marijuana from the federal list of controlled substances.
Nearly every candidate has offered support for the federal legalization of recreational marijuana and many have called to expunge federal charges for those prosecuted for pot use.
Ten states and the District of Columbia have legalized recreational marijuana use and more states have signaled interest in doing so. Public opinion has shifted in favor of legalization, with 61% of Americans believing marijuana should be legal. Democrats support it even more, with 76% favoring legal marijuana, according to a 2018 poll of 2,348 American adults.
Critics of recreational marijuana fear it would make the drug too accessible and could promote misuse, but supporters cite increased tax revenues and racial imbalances in criminal sentences for drug offenders as reasons for legalization.
Here is what the Democratic presidential candidates have said and done about legalization:
Sen. Cory Booker of New Jersey reintroduced a bill in February that would legalize marijuana nationwide, expunge federal convictions and allow those prosecuted for use to petition the courts for shorter sentences. Booker first introduced the Marijuana Justice Act in 2017, but it was not taken up for a vote.
Other Democratic presidential candidates have offered support for the proposal, with New York Sen. Kirsten Gillibrand, California Sen. Kamala Harris, Massachusetts Sen. Elizabeth Warren and Vermont Sen. Bernie Sanders co-sponsoring the bill.
Sanders has been a major supporter of marijuana legalization and introduced the Senate's first-ever bill to end the federal prohibition on marijuana in 2015.
Ohio Rep. Tim Ryan, who announced his candidacy earlier this month, and Hawaii Rep. Tulsi Gabbard also signed on to the Marijuana Justice Act's companion bill in the House.
Though Booker's proposal has support from a number of Democrats, it faces a tough road in the Senate. Last year, Senate Majority Leader Mitch McConnell, R-Ky., said he does "not have any plans to endorse the legalization of marijuana," when Senate Minority Leader Chuck Schumer, D-N.Y., introduced a bill that would decriminalize the drug.
Republicans hold a 53-47 edge in the Senate, although Democrats control the House.
The Marijuana Justice Act is only the most recent bill that candidates have supported.
Though some candidates have not signed onto marijuana-related bills, they've still voiced support for legalization.
Former Colorado Gov. John Hickenlooper initially condemned his state's decision to legalize recreational pot, calling it "reckless." Since then, he signed a number of cannabis-related bills into law, but he's stopped short of supporting the end of federal prohibition.
Hickenlooper said during a CNN Town Hall in March that he wouldn't call for the federal government to legalize marijuana and would instead let the states decide for themselves.
