As was previously discussed, marijuana is very easily attainable in America.
Therefore, marijuana enforcement is not only enormously expensive but also highly
ineffective in preventing the distribution of marijuana. Most research finds the cost of
enforcing marijuana prohibition to be around $15 billion. In 2007, Jon Gettman
estimated the cost to be $16.4 billion; while in 2010, Jeffrey Miron estimated the cost to
be roughly $13.7. The average of their findings would be approximately $15.1 billion as
the cost of enforcing marijuana prohibition, which will be the figure used in calculating
the total economic effect of legalizing marijuana.
