On cannabis, chloral hydrate, and career cycles of psychotropic drugs in medicine.
This article compares the careers of two psychotropic drugs in Western psychiatry, with a focus on the nineteenth century: Cannabis indica and chloral hydrate. They were used by doctors for similar indications, such as mania, delirium tremens, and what we would now call drug dependence. The two show similar career paths consisting of three phases: initial enthusiasm and therapeutic optimism; subsequent negative appraisal; and finally, limited use. These cycles, which we term "Seige cycles," are generally typical of the careers of psychotropic drugs in modern medicine. However, differences in the careers of both drugs are also established. The phases of chloral show relatively higher peaks and lower valleys than those of cannabis. Chloral is the first typically "modern" psychotropic drug; a synthetic, it was introduced in 1869 at a time of growing asylum populations, pharmaceutical interests, and high cultural expectations of scientific medicine. Cannabis indica, introduced in the 1840s, is typically a "premodern" drug steeped in the climate of cultural Romanticism. We conclude that the analytical concept of the Seige cycle is a useful tool for future research into drug careers in medicine.
