The war on drugs has led to repeated demands from academics and economists (including 3 Nobel Prize winners) to change the current flawed strategy that seems to ignore the elementary laws of supply and demand.
Milton Friedman has long advocated the legalization of drugs; indeed, the world famous economist even stated that:
And he isn’t the only one defending this point of view: Gary Becker (Nobel-Prize economist), George Shultz, the U.S. Secretary of State from 1982 to 1989, and National Humanities Medal winner Thomas Sowell have also criticised the current approach.
It has become clear that the war on drugs is not only ineffective, but expensive too. A lot of money spent by governments is used to catch the people who buy or sell illegal drugs, to prosecute them in court, and to send them to jail. In the United States, under current rules regarding parole and probation, a positive urine test for drugs can send a parolee or probationer to prison, regardless of the original offense. Over $100 billion is spent globally each year on enforcing the war on drugs .
Between 1919 and 1933, alcohol was illegal in the United States; historians believe that the decision to end prohibition on March 23 1933 was partly fuelled by the desire to raise tax revenue in the 1930s when the depression started. Today in the US, the risk of a double-dip recession is very high, and cuts are necessary in many parts of the world. Yet the President’s Fiscal Year (FY) 2011 Nation requests $15.5 billion to reduce drug use in the United States. This represents an increase of $521.1 million (3.5%) over the FY 2010 level of $15.0 billion. In the European Union, state expenditure on the drug problem costs about €34 billion . A recent report by Harvard economist Jeffrey A. Miron estimates that legalizing marijuana would save $7.7 billion per year in government expenditure on enforcement of prohibition. $5.3 billion of this savings could accrue to state and local governments, while the federal government could save $2.4 billion.
The illicit drug market, on the other hand, seems to be doing very well. According to the 2007 UN World Drug Report, this market was estimated at $322 billion, and that despite the seizures and losses, the value of drugs increase substantially as the move from producer to consumer . A study of drug dealers in
Washington in the 1980s concluded that they could earn up to $30/h – compared with the $7/h average from legal employment. Robert Neild, a Cambridge University professor, asserts that third world states are often “undermined, sometimes destroyed” by the violence and corruption that goes with this lucrative market. Clearly the war on drugs affects not only the economy of Western countries, but the stability of many developing countries as well, especially in Latin America, the Caribbean and western Africa. A regulated and legal market could “fix” many of these problems.
Legalization is now more necessary than ever, and it is important for governments to address the problem in order to avoid other long-term socio-economic risks such as the “cyclic creation of permanent underclass”, as theorized by Eric Blumenson and Eva S. Nilsens . The CATO Institute’s “The Budgetary Impact of Ending Drug Prohibition” estimates that drug legalization in the US could yield tax revenue of $46.7 billion annually (assuming legal drugs were taxed at rates comparable to those on alcohol and tobacco).
It is thus clear that money is being spent excessively, ineffectively and sometimes even dangerously. The billions of dollars spent by governments each year fail to address economic realities, and ignore the exponential demand for policy change.
