The overdose crisis is largely driven by the fact that once addicted to legal opioids, people seek out illegal ones — heroin, for example — to fend off the agony of withdrawal once they can’t get, or afford, any more pills. Last year, 64,000 Americans died from overdoses. Some 58,000 Americans died in the Vietnam War.

Experts rightly point out that a large share of opioid addiction stems not from prescribed use but from people selling the drugs secondhand on the black market, or from teenagers stealing them from their parents. That’s important, but it doesn’t help the argument for legalization. Because the point remains: When these drugs become more widely available, more people avail themselves of them. How would stacking heroin or OxyContin next to the Jim Beam lower the availability? Liquor companies advertise — a lot. Would we let, say, Pfizer run ads for their brand of heroin? At least it might cut down on the Viagra commercials.
