Drug prohibition increases violence by creating black markets with no legal dispute resolution

Confirmed recorded as “Confirmed (Historical Evidence)” Chasing the Scream

The pattern is documented in two natural experiments: US alcohol Prohibition (1920-1933) produced gang violence over bootlegging territory; Prohibition repeal eliminated this violence. The drug war in Mexico, Central America, and US inner cities produced cartel warfare over supply routes valued by prohibition-created profit margins. Miron (2004, The Budgetary Implications of Marijuana Prohibition) estimated prohibition-related violence costs. The mechanism: legal markets resolve disputes through contracts and courts; illegal markets resolve them through violence.
