U.S. War on Drugs is a Bust

Writing in The Wall Street Journal, economists Gary Becker and Kevin Murphy argue that the war on drugs that Nixon started in 1971 has failed and must be reconsidered. "By most accounts, the gains from the war have been modest at best." And the human cost is very high:

The total number of persons incarcerated in state and federal prisons in the U.S. has grown from 330,000 in 1980 to about 1.6 million today. Much of the increase in this population is directly due to the war on drugs and the severe punishment for persons convicted of drug trafficking. About 50% of the inmates in federal prisons and 20% of those in state prisons have been convicted of either selling or using drugs. The many minor drug traffickers and drug users who spend time in jail find fewer opportunities for legal employment after they get out of prison, and they develop better skills at criminal activities.

The war on drugs drives up drug prices and forces the formation of large criminal cartels:

The paradox of the war on drugs is that the harder governments push the fight, the higher drug prices become to compensate for the greater risks. That leads to larger profits for traffickers who avoid being punished. This is why larger drug gangs often benefit from a tougher war on drugs, especially if the war mainly targets small-fry dealers and not the major drug gangs. Moreover, to the extent that a more aggressive war on drugs leads dealers to respond with higher levels of violence and corruption, an increase in enforcement can exacerbate the costs imposed on society.

The large profits for drug dealers who avoid being caught and punished encourage them to try to bribe and intimidate police, politicians, the military and anyone else involved in the war against drugs. If police and officials resist bribes and try to enforce antidrug laws, they are threatened with violence and often begin to fear for their lives and those of their families.

In 2001 Portugal decriminalized the sale of drugs, but not the use:

Decriminalization would reduce the bloated U.S. prison population since drug users could no longer be sent to jail. Decriminalization would make it easier for drug addicts to openly seek help from clinics and self-help groups, and it would make companies more likely to develop products and methods that address addiction.

...A study published in 2010 in the British Journal of Criminology found that in Portugal since decriminalization, imprisonment on drug-related charges has gone down; drug use among young persons appears to have increased only modestly, if at all; visits to clinics that help with drug addictions and diseases from drug use have increased; and opiate-related deaths have fallen.

Full decriminalization, of sale as well as use, should be considered:

Decriminalization would reduce the bloated U.S. prison population since drug users could no longer be sent to jail. Decriminalization would make it easier for drug addicts to openly seek help from clinics and self-help groups, and it would make companies more likely to develop products and methods that address addiction.

Some evidence is available on the effects of Portugal's decriminalization of drugs, which began in 2001. A study published in 2010 in the British Journal of Criminology found that in Portugal since decriminalization, imprisonment on drug-related charges has gone down; drug use among young persons appears to have increased only modestly, if at all; visits to clinics that help with drug addictions and diseases from drug use have increased; and opiate-related deaths have fallen.
