Overview

New Jersey uses an effect-based approach to cannabis DUI enforcement. The state legalized recreational cannabis in 2020 and has specifically relied on Drug Recognition Expert evaluations as the primary method for identifying cannabis-impaired drivers rather than setting a per se THC limit.

New Jersey has significantly expanded its DRE program since legalization. The state has also authorized oral fluid roadside testing as a screening tool. New Jersey's approach reflects a philosophy that observable impairment is a better indicator of driving risk than arbitrary blood THC levels.
