Watch: Trump Says 'Yes' To Medical Marijuana, 'No' To Deporting Justin Bieber

Donald Trump's position on cannabis appears to have flip-flopped wildly over the years. (No comb-over jokes - promise.)

In a Nov. 23 video, GQ visited Trump Tower to ask Trump one question: what will make America great again? From there, he gave his take on some of America's most polarizing topics, including marijuana legalization.

"Legalized marijuana is always a very difficult question - for medicinal purposes and medical purposes, it's fine," says Trump in the video.

Earlier this year, Trump told FOX's Sean Hannity he supports medical users "100 percent," but added that overall, marijuana legalization has been "a bad thing for Colorado." He added the Evergreen state is now facing some "big, big problems." (Never mind that Colorado seems to be doing okay on most fronts.)

But back in 1990, Trump told the Sarasota Herald America's drug policy was "a joke," and legalizing all drugs was the answer when it came to "tak[ing] the profit away from these drug czars."

As for Trump's own taste for illicit substances? He doesn't have one, apparently.

He claims in his 2000 book, The America We Deserve, that he's "never taken drugs of any kind," including coffee, alcohol, or tobacco.

If he didn't have such strong views on the subject of sex, Trump might be a candidate for Most Surprising Proponent of the Straight Edge Movement, as well as POTUS.

John Sinclair is one of the lesser-known people in cannabis culture, but he’s a very important figure, particularly for anti-prohibition activists. Sinclair is a native of Flint, Michigan, far from the hippie epicenters in California or the Warhol scene of the Big Apple. The scene in Michigan was grittier and more blue collar.
