Prohibition was a failure in the 1920s, and, for similar reasons, the so-called war on drugs has been a disaster. Forty years after U.S. President Richard Nixon declared this war, consumption worldwide is up, violence has increased and the rule of law has collapsed, especially in Latin America.

Basic economics tells us that when there is artificial pressure on supply, prices go up and margins increase — the perfect incentives for criminal activities. The same mistake was made in the United States almost a century ago with Prohibition. As early as 1925, some observers started to see that this policy, far from stopping crime, was leading to the formation of large networks of well-funded crime syndicates.

U.S. President Franklin Roosevelt was elected in 1932 partly due to his campaign promise to end Prohibition. People who originally favored Prohibition, such as John D. Rockefeller Jr., later fought for its repeal because of the devastating effects it had on agriculture and industry.
