Jeb Bush has tried it, Joe Biden opposes any legalization and Hillary Clinton thinks it is a chance to test the “laboratories of democracy.”

As more states move to legalize medical and recreational marijuana, more attention may be drawn to the 2016 presidential hopefuls’ stances on legislation. Recovery Brands, an online addiction rehabilitation network, analyzed past interviews and legislative actions of the current candidates -- and some who may become candidates -- to determine where they stand.

Twenty three states have legalized medical marijuana and four states and the District of Columbia have legalized both medical and recreational cannabis.

Americans have become more open about marijuana use. About 44% of U.S. citizens said they have tried the drug, according to a recent Gallup poll.

Most potential Democratic candidates have been vocally against the War on Drugs and either support or are unclear on medical marijuana legalization. However, Vice President Joe Biden stands out from the pack—he is against any legalization and has been a supporter of the War on Drugs, though he upholds the Obama administration’s decision to not enforce federal law in states that have legalized cannabis.

Though Biden hasn't officially declared his candidacy, he is expected to announce an official decision in August.

Of the Democratic candidates, only Vermont Senator Bernie Sanders and former Rhode Island Governor Lincoln Chafee have admitted to trying marijuana. Former Florida Governor Jeb Bush, Kentucky Senator Rand Paul and Texas Senator Ted Cruz were the only Republicans to have admitted to using the drug.

Though former Secretary of State Hillary Clinton has said on the record that she has never partaken, she has said that medical marijuana legalization could aid those suffering from extreme conditions and supports additional research. As for recreational cannabis, she has taken a wait-and-see stance to observe how states that have already legalized it fare.

A spokesperson for Recovery Brands said the organization did not include business mogul Donald Trump in the analysis “given the controversy around his true aims in the 2016 race.”

Though Trump was not included in the analysis, he has gone on the record saying he has never consumed alcohol or taken drugs after the death of his brother, Fred, from alcoholism in 1981.
