Grass Trailer (2000)

Trailer for the documentary Grass.

Marijuana is the most controversial drug of the twentieth century. Smoked by generations of musicians, students and workers to little discernible ill effect, it continues to be reviled by the vast majority of governments around the world. With his new film, Grass, veteran filmer Ron Mann brings his impeccable historical facility and story telling skills to recount how a relatively harmless drug has been demonized for decades.
