The Economics of Illegal Drugs

As a teenager I saw the war on drugs up close. Then I studied it as an economist and saw it differently

By Roland Fryer. Excerpts:

"When demand for a drug is inelastic—meaning users don’t reduce consumption much even as prices rise—supply-side enforcement doesn’t starve traffickers. It enriches them."

"When enforcement raises costs, the street price goes up. If demand is elastic, consumers cut back, total spending falls, and less money flows to traffickers. But if demand is inelastic, as decades of evidence suggest it is for hard drugs, consumers cut back only modestly, total spending increases, and more money flows into the drug trade."

"legalize and tax. When demand is sufficiently inelastic, an excise tax on a legalized drug . . . reduces consumption more than any “war” on the drug. With legalization, producers prefer paying the tax to going underground, and enforcement costs collapse."

"in the 1980s and ’90s. With the rise of crack, homicide rates doubled among black males 14 to 17 while fetal deaths among blacks sharply increased. Yet even as crack use persisted at 60% to 75% of its peak level through 2000, the violence almost disappeared. The initial violence was driven not by drug use but by the struggle to establish property rights in illegal markets. Once those rights were established and crack prices fell, the violence subsided."

"Portugal and Switzerland represent partial steps: decriminalizing use while keeping supply illegal, or medicalizing supply for the most dependent users."

"Portugal decriminalized all drugs in 2001 and redirected resources to treatment. Annual drug-related deaths fell from 76 to 16 by 2012; HIV infections among users fell more than 90%; drug use didn’t spike."

"Switzerland began prescribing pharmaceutical-grade heroin to its hardest cases in the 1990s. Muggings by participants dropped 70%; opioid-related criminal cases nationally declined from 20,000 a year to 5,000."

"cocaine retails at 262 times its farm gate price—a markup attributable to the risk premium of illegality."

"addicts respond far more to permanent price changes than to temporary ones."

"In November 2025, the Congressional Budget Office’s director testified that he had no evidence the interdiction campaign has affected drug use or prices in the U.S. A classic RAND Corp. study found decades ago that treatment is 23 times as cost-effective as source-country control and 10 times as cost-effective as interdiction."
