Overview

Michigan maintains a zero-tolerance standard for cannabis and driving despite legalizing recreational cannabis in 2018. Any detectable amount of THC in a driver's system can result in a DUI charge, creating tension between the state's cannabis legalization and its DUI laws.

This strict standard has been controversial because regular cannabis users may have detectable THC levels even when not impaired. Michigan law enforcement uses blood testing, field sobriety tests, and DRE evaluations. The state has been considering legislative changes to move toward a per se limit, but no changes have been enacted.
