Looking at the replies in this thread tells me that many, many people are unaware of the history of alcohol prohibition in America. From 1920 to 1933 production and consumption of alcoholic beverages was forbidden in America by Constitutional amendment 18, repealed by amendment 21. This period created organized crime in America, and resulted in many social problems. There are different opinions about how much of a disaster this social experiment was, but most historians agree that it was a disaster. Marijuana prohibition only came into being after alcohol prohibition was repealed, partly because the officials who had been in charge of enforcing alcohol prohibition needed a new job. Many former moonshiners welcomed marijuana prohibition since it also created new jobs for them.
