Webshaykh’s note: In the process of researching the medical aspects of the chewing of qât (Catha edulis) leaves in Yemen, I consulted an important study published almost forty years by the distinguished historian Orientalist (in the best sense — and there is a best sense — of the word) Franz Rosenthal. This was his The Herb: Hashish versus Medieval Muslim Society (Leiden: Brill, 1971). Appearing at a time when hashish had become a household word in America, Rosenthal sorts through legal, medical and literary sources to provide a historical overview of the issues surrounding the use of hashish, the plant known as qinnab in Arabic (Cannabis sp). This is a valuable resource, but also worth a good read to get a sense of how an addictive socially popular drug was viewed for almost the last full millennium.
