Grass, narrated by actor/activist Woody Harrelson, takes a highly spirited and innovative look into one of America's most deeply rooted cultural myths: the evils of "pot", "cannabis", "weed", "dubich", "doobie", "shrub", or whatever man. From the story of America's first drug czar, to the absurd scare tactics behind propaganda films like Reefer Madness, and Marijuana: Threat or Menace, director Ron Mann (Comic Book Confidential, Twist) poignantly and humorously exposes the social, political and economic facts behind this enduring weed, and the extent to which it has profoundly shaped our culture.
