Charles BaudelaireRead about another entry on the list.
The 19th-century French poet is one of the great chroniclers of drug use and his memoir Artificial Paradises features a detailed analysis of hashish. He was a member, along with other influential Parisian authors Alexandre Dumas, Victor Hugo and Honoré de Balzac, of Club des Hachichins (Hashish-Eaters’ Club), which met regularly between 1844 and 1849. “At first, a certain absurd, irresistible hilarity overcomes you,” he noted of their experiments. But, surprisingly, although far from strait-laced – he smoked opium and drank very heavily – Baudelaire was unconvinced by the appeal of hashish. It boosted creativity, he found, but artists risked becoming too dependent on it.
