The War That Would Not End

In June 1971, President Richard Nixon stood at a podium and declared drug abuse public enemy number one. The War on Drugs had begun. Over the following decades, under Nixon, Reagan, and their successors, the United States would spend over a trillion dollars on enforcement, interdiction, and incarceration. The goal was to eliminate the drug trade by making it so dangerous and so costly that suppliers would give up and users would stop.

The suppliers didn't give up. They adapted.

As police cracked down on marijuana, traffickers shifted to cocaine, which was more profitable per unit of weight and easier to smuggle. When cocaine routes were disrupted, suppliers concentrated the product into crack, which was cheaper and more addictive. When heroin supply chains were targeted, chemists developed synthetic opioids like fentanyl, which is fifty times more potent than heroin and can be manufactured in a basement. Each round of enforcement produced a more concentrated, more dangerous, more profitable product.

This pattern is so consistent that it has a name. Criminologist Richard Cowan called it the Iron Law of Prohibition: the harder the enforcement, the more potent the substance becomes. The same dynamic played out during alcohol Prohibition in the 1920s, when beer and wine gave way to bathtub gin and moonshine. Traffickers respond to enforcement by maximizing value per unit of volume. The result is drugs that are smaller, easier to hide, and far more likely to kill.

Meanwhile, the human cost mounted. The United States incarcerated more people per capita than any country on earth, and the burden fell disproportionately on Black and Hispanic communities. Families were shattered. Neighborhoods were hollowed out. Men convicted of nonviolent drug offenses received sentences longer than those given to some violent criminals. The prison system, swollen beyond capacity, became a graduate school for criminal networks rather than a deterrent against them.

Fifty years and a trillion dollars later, drug use in America hasn't meaningfully declined. Overdose deaths have reached record highs. The cartels are richer and more powerful than ever. And the communities the War on Drugs was supposed to protect have been among its most devastating casualties.

The war didn't fail because the people fighting it were incompetent or insincere. It failed because it was built on an assumption that turned out to be wrong: that you can eliminate demand by attacking supply. You cannot. You can only change the shape of the supply, and in this case, the shape it took was smaller, stronger, and deadlier.
