Overview

Arkansas follows an effect-based approach to cannabis DUI enforcement. There is no specific per se THC limit, so prosecutors must demonstrate that a driver was actually impaired by cannabis. Arkansas has a medical cannabis program but no recreational legalization.

Chemical testing, field sobriety tests, and Drug Recognition Expert evaluations are all used to establish impairment. Arkansas's implied consent law requires drivers to submit to chemical testing when lawfully requested by an officer.
