Watch This: The ‘Sinister Reason’ Cannabis Is Illegal

Adam Ruins Everything is a show that started as video clips on College Humor before moving to the truTV network. The host, Adam Conover, examines popular myths and misconceptions and “ruins” them for the audience by presenting facts and citing references that refute a particular claim.

In one segment, Conover explores “The Sinister Reason Weed Is Illegal.” Addressing multiple issues, he starts by reminding viewers how long ago we started growing cannabis crops, covers how widely it was used in the past (even in over-the-counter-medications), and explains why the government eventually decided it should be banned. (I’ll give you a hint: racism.)

Watch the video. It’s one of those things you laugh at while watching it, then you sit back and realize all of those jokes were real facts.
