Directed and edited by Australian filmmaker Anthony Clarke, who worked on both Coverup: Behind the Iran Contra Affair and The Panama Deception, this is a feature-length documentary about marijuana as both a beneficial plant (it could help solve environmental and social problems) and a black-market drug demonized by governments. Scientists, academics, and professionals across the world are interviewed, and the music is provided by Jackson Browne, Yothi Yindi, Sirocco, and Stephen Housden, among others.
