Marijuana

Cannabis has been used by people for at least two and a half thousand years. Mourners burned it in braziers in the Pamir mountains around 500 BC, Chinese herbals listed it, Indian texts made it sacred, and for most of recorded history the same plant was rope, sailcloth, paper and medicine. Then in the twentieth century a plant became a crime. Harry Anslinger built a bureau on it, Hollywood made Reefer Madness, a 1937 tax act ended the legal trade, and in 1970 the United States placed cannabis in Schedule I alongside heroin, where, formally, it largely remains. The war that followed filled prisons unequally and never removed the plant from a single city. Alongside all of it, cannabis kept doing what it had always done: it ran through jazz and reggae and hip-hop, it built its own cinema and its own comedy, and it became the subject of real science after Raphael Mechoulam isolated THC in 1964 and researchers found the receptor system it acts on. Then the law began to move, California in 1996, Colorado and Washington in 2012, Uruguay, Canada, Thailand, Germany. This is the whole arc: the plant, the archaeology, the propaganda, the records, the films, the raids, the research and the votes.

A chronological documentary of 571 moments spanning 4800 BC–2026 on Loreline.
