Cannabis made its way to the United States by means of the immigrant labour force. Once the plant had been shared with black labourers, it didn’t take long for American lawmakers to decry cannabis as the vice of "inferior races". Enter an era of propaganda designed to whip up fear among the public. Dishonest and discriminatory campaigns, spearheaded by legislators and the press, spread vicious lies about a plant that had been used by humanity for thousands of years. The result: cannabis was given a schedule 1 classification, alongside heroin.

In this entertaining and expertly crafted graphic novel, Box Brown offers a rich, persuasive and eye-opening guide to the complex and troubled history of cannabis in America.
