Addiction and incarceration: The failed war on drugs

Published December 8, 2024 · 8 min read · Updated April 2026

Approximately 65% of the US prison population has a substance use disorder. Incarceration does not treat addiction and often worsens it.

The failure of criminalization

Punishing addiction as a criminal problem rather than treating it as a medical condition has produced mass incarceration without reducing drug use. The US spends approximately $35 billion annually on drug-related incarceration while providing treatment to fewer than 10% of incarcerated people with SUD.

What works instead

Drug courts (reduce recidivism by 8-14%). MAT in prisons and jails (reduces overdose death post-release). Diversion programs routing people to treatment instead of jail. Decriminalization of personal use (Portugal model).

The post-release crisis

The first two weeks after release are the highest-risk period for overdose death. Tolerance drops during incarceration but supply access returns immediately. MAT initiated before release saves lives.
