The Cato Institute’s Jeff Singer and Michael Fox mark Repeal Day by examining how alcohol prohibition and the modern drug war share the same destructive logic: criminalizing peaceful people, fueling black markets, corrupting law enforcement incentives, and empowering violent traffickers. Drawing on real-world examples of overdose deaths, civil forfeiture, and policing excesses, they argue for a consistent, liberty-based framework that treats drug users with the same legal respect afforded to alcohol consumers.
