It's High Time: A Common Sense Approach to Marijuana-Impaired Driving

With medical and recreational marijuana now legal in many States, law enforcement needs a logical solution for identifying cannabis-impaired drivers. This report looks at how alcohol-impaired driving is assessed and whether cannabis-impairment can be identified in the same manner. It discusses metabolism of alcohol versus cannabis and the ramifications of per se-based arrests and zero tolerance policies on legal users of cannabis. In addition, it examines how law enforcement determines driving impairment and types of tests for drug-impaired drivers currently in use or in development. It recommends an approach similar to Canada's involving training drug recognition expert (DRE)-qualified officers to assess drivers along with the use of dashcams and bodycams. It also suggests that funding be prioritized toward toxicology laboratories to speed toxicology screens to corroborate the presence of cannabis.
