The emerging significance of cannabis components other than THC was again a prominent theme when the International Association of Cannabis as Medicine (IACM) met in Cologne in early October, 2007.

Raphael Mechoulam of the Hebrew University, Jerusalem, Faculty of Medicine gave a talk on cannabidiol on the occasion, he noted, of his 45th year of involvement in the field. In October, 1962 Mechoulam had just gotten his PhD in chemistry and was looking for a research project that might lead to tenure at the Weizmann Institute. He chose to analyze the components of cannabis, he said, thinking “it’s a minor project, it will be finished off in six months.”
Hashish of Lebanese origin was obtained from the police—“There is a fantastic collaboration between Arabs and Jews in smuggling,” Mechoulam observed—and a dozen constituents were then identified by two types of chromatography. (Some cannabis constituents had been identified previously, including CBD, which Roger Adams of the University of Illinois isolated in the early 1940s.)
