In one famous study where monkeys were force-fed huge amounts of cannabis smoke the results showed brain damage, but the damage was more likely due to carbon-monoxide poisoning and oxygen deprivation. The most comprehensive study of the health effects of marijuana on humans was done recently by Kaiser Health Group. They surveyed 65,000 patients and compared the medical records of long-term pot smokers versus non-smokers. They found no significant differences in the health histories of the two groups. The US Drug Enforcement Agency's own Chief Administrative Law Judge studied the health effects of marijuana for two years and accumulated 15 volumes of research. He concluded that marijuana is probably among the safest drugs known to man. Alcohol leads the field in damage to individuals and society, by almost any standard of measurement, over all the illegal drugs combined. However, US alcohol prohibition was a disaster. Arrests for public drunkenness soared, homicides skyrocketed, corruption flourished, and it caused a teenage drinking epidemic. Just because a drug has dangers doesn't automatically mean that trying to prohibit it is the best solution. Lady Greenfield asks why people smoke cannabis. When Canada's 1970 Le Dain Commission asked that question, people told them simply: "It feels good." That is the same reason that people play golf, drink beer, or engage in any number of other activities. But the vast majority of them have the good sense not to overdo any form of recreation.
