Overview

Alaska is an effect-based state for cannabis DUI enforcement. Despite legalizing recreational cannabis in 2014, Alaska does not set a specific THC blood concentration limit. Instead, the state requires proof of actual impairment.

Law enforcement uses field sobriety tests, Drug Recognition Expert evaluations, and blood tests to build DUI cases. Alaska has some of the stricter implied consent penalties in the country, with mandatory jail time for test refusals.
