Arizona pot smokers will learn April 22 whether they can be busted for driving while impaired weeks after using the drug.
The Arizona Supreme Court is going to issue an opinion on a case involving Hrach Shilgevorkyan, who was charged in December 2010 with driving with drugs in his system.
A trial court dismissed his charges on the basis of not having marijuana’s active ingredient or primary, active metabolite in his system. Testing found he had only a secondary, non-active metabolite that can stay in the system for up to a month.
The Arizona Court of Appeals reversed the lower-court ruling.
The Supreme Court’s decision will affect all marijuana users, but will have special significance for people who can legally use the drug under the state’s Medical Marijuana Act, a 2010 ballot measure legalizing the drug for medicinal purposes.
