'Le Club des Hachichins' was a 19th-century French club of hash users dedicated to exploring the depths of the human condition through drug-induced experiences, primarily the resin of the cannabis plant. Its members were a collection of prominent French elites, intellectuals, and literary giants such as Victor Hugo, Alexandre Dumas, Charles Baudelaire, Gérard de Nerval, and Honoré de Balzac. Furthermore, Dr. Jacques-Joseph Moreau, founder of the club, was the first psychiatrist to explore the effects of cannabis on the mind with a rather special hashish dessert, dawamesk. The Club decisively influenced future research on medical cannabis, particularly in the field of mental illness.
