The iron law of prohibition is a term coined by Richard Cowan which states that "the more intense the law enforcement, the more potent the prohibited substance becomes." This is based on the premise that when drugs or alcohol are prohibited, they will be produced only in black markets in their most concentrated and powerful forms. If all alcohol beverages are prohibited, a bootlegger will be more profitable if he smuggles highly distilled liquors than if he smuggles the same volume of small beer. In addition, the black-market goods are more likely to be adulterated with unknown or dangerous substances. The government cannot regulate and inspect the
production process, and harmed consumers have no recourse in law.
