This 2007 article published in the Bulletin of Cannabis Reform Government looks at marijuana usage in the United States, its retail value and the tax revenue that is lost as a result of marijuana laws, as they stood in 2007. Government reports indicated that the nation’s marijuana laws cost taxpayers $41.8 billion annually. This calculation was based on (a) a reconciliation of estimates of the annual supply of marijuana in the U.S. and estimates of its overall value and (b) Office of Management and Budget (OMB) data on the share of the Gross Domestic Product diverted by regulatory taxes to U.S. Government budgets.
