So, naturally, many are asking: where do the 2020 candidates stand on cannabis? Here's what we found.

Biden has called for decriminalizing marijuana use and the automatic expungement of all marijuana-related convictions.

Biden: "We should move in a direction to make sure it’s not a criminal offense, it’s a civil offense."

Biden supports the federal legalization of medical marijuana, and opposes legalizing recreational marijuana nationwide.

Biden also wants to move marijuana from a Schedule I to a Schedule II drug to allow scientific research on its effects.

Biden told KMOV-TV: "We have to do some more study on impact on mental acuity."

Trump has said he supports medical marijuana on a state level, but his 2021 budget ends protections for said programs.

Trump's 2020 campaign communications director, Marc Lotter told 8NewsNow in Feb. that marijuana should be "kept illegal."
