Ruling: Marijuana law doesn't give DUI immunity

PHOENIX (AP) - A state appellate court ruling says Arizona's medical marijuana law doesn't give authorized users immunity from prosecution under a law against driving while there is marijuana or its chemical compound in a person's body.

A jury had acquitted a man of driving while impaired but convicted him of driving under a DUI law prohibiting a person from driving while having a prohibited drug or its compound in his or her body.

A three-judge Court of Appeals panel's ruling Tuesday lets stand Travis Lance Darrah's conviction.

Darrah's appeal argued that part of the medical marijuana law was intended to make authorized users immune from prosecution unless they drive while impaired.

The Court of Appeals said the medical marijuana law could have included a blanket immunity provision but didn't.
