Overview

The District of Columbia follows an effect-based approach to cannabis DUI enforcement. Despite legalizing recreational cannabis possession and home cultivation in 2014 (Initiative 71), DC has not established a per se THC driving limit. Prosecutors must prove actual impairment.

DC's unique legal status — where Congress can override local laws — creates additional complexity. The district uses field sobriety tests, DRE evaluations, and chemical testing. DC has expanded its DRE program significantly since cannabis legalization.
