A Celebration of Canabis Culture Spliffs is more than just a book about cannabis and getting stoned. It's the history of a culture. From the ancient Scythians and the Cult of the Assasins through its heady heyday among the flower-power hippies of the 1960s and the sensimilla revolution that was to follow, right up to recent renaissance in hashish making in the marijuana-mecca of Amsterdam. 256 pages.
