Overview

Indiana enforces a zero-tolerance standard for cannabis and driving. Any detectable amount of THC or its metabolites in a driver's system constitutes a violation. Cannabis is illegal in Indiana for both medical and recreational use.

Because cannabis is fully illegal in Indiana, a DUI stop involving cannabis typically results in additional charges for possession. The state's zero-tolerance approach means that THC metabolites from consumption days or weeks earlier can still trigger a DUI charge.
