 Since then, the word has been associated with the stoner comedy genre, in films including the 1978 "Up In Smoke" and other media including the New York Off-Broadway show "The Marijuana-Logues".For legal, research and statistical reference, "marijuana" generally refers to the dried leaves and flowering tops (herbal cannabis), with by-products such as hashish or hash oil being uniquely defined and regulated.Many legal references prefer the term "cannabis", for instance in the Single Convention on Narcotic Drugs.
