“There are four interest groups that will make sure our efforts are frustrated: First, law enforcement. Drug laws are a make-work project for police. (The marijuana laws were written to provide work for unemployed alcohol enforcement officers during the Depression). Secondly, politicians need non-voting scapegoats. Third, banquet circuit scientists, who (for a price) provide rationalizations for anti-drug laws. Fourth, the drug cartels’ profit margin flows from the risk premium on contraband drugs.” [Meyers 1967]
