History of Cannabis

A Brief History of Cannabis

It may seem as if the global drug war has been around forever, but nothing could be further from the truth. In fact, on the timeline of humanity’s long relationship with cannabis, the prohibition which is just now coming to an end barely registers so much as a blip. If the known history of human cannabis cultivation were mapped out along the length of a football field, the period in which cannabis was legal in every country of the world would span almost completely from one end zone to the other; the entire history of cannabis prohibition, meanwhile, would take up less than one inch of the final yard.
