Marijuana, however, appears to have been the victim of historical bad luck: Its health effects are no more dire than those of alcohol or tobacco, but over the centuries the plant lacked international corporate backing or fiscal influence. Unlike tobacco and alcohol, which was banned temporarily in the United States during Prohibition but was quickly reinstated to legal (albeit heavily regulated) status, marijuana never became part of the personal habits of influential leaders and celebrities. (That makes sense, of course, given the go-go nature of capitalism and the traits required for success anyone who did make marijuana part of his personal habits would most likely not have become an influential leader or celebrity in the first place.) Instead, the mellow plant lodged itself first in peasant and then in youth subcultures, where it gained a reputation as a gateway drug to harder, harsher illegal substances like heroin and cocaine
