Overview

Idaho is an effect-based state for cannabis DUI enforcement, though cannabis remains completely illegal in the state for both medical and recreational purposes. There is no per se THC limit; prosecutors must demonstrate actual impairment.

Because cannabis is entirely illegal in Idaho, any possession found during a DUI stop will result in additional criminal charges beyond the DUI itself. Idaho's strict stance on cannabis means that even CBD products containing trace THC can create legal issues.
