Speculations on the Nature and Pattern of Opium Smoking

Abstract

Opium smoking began spreading slowly but steadily in China from early in the 18th Century. It grew through the 19th Century to the point that by the end of the century it became a nearly universal practice among males in some regions. While estimates vary, it appears that most smokers consumed six grams or less daily. Addicted smokers were occasionally found among those smoking as little as three grams daily, but more often addicted smokers reported use of about 12 grams a day or more. An individual smoking twelve grams of opium probably ingests about 80 mg. of morphine. Thirty mg. of morphine daily may induce some withdrawal signs, while 60 mg. daily are clearly addicting. While testimony varied widely, it appears likely that most opium smokers were not disabled by their practice. This appears to be the case today, too, among those peoples in southeast Asia who have continued to smoke opium. There appear to be social and perhaps psychophysiological forces which work toward limiting the liabilities of drug use.
