It is not known when Rastafari first claimed cannabis to be sacred, but it is clear that by the late 1940s Rastafari was associated with cannabis smoking at the Pinnacle community of Leonard Howell. Rastafari see cannabis as a sacramental and deeply beneficial plant that is the Tree of Life mentioned in the Bible and quote , "... the herb is the healing of the nations." The use of cannabis, and particularly of long-stemmed water-pipes called chalices, is an integral part of what Rastafari call "reasoning sessions" where members join together to discuss life according to the Rasta perspective. They see the use of cannabis as bringing them closer to God (Jah), allowing the user to penetrate the truth of things more clearly.
