In a crucial win for patients in Michigan, the state Supreme Court ruled yesterday that the state’s zero tolerance driving under the influence law does not apply to medical marijuana patients when it is based on the mere presence of THC in a patient’s blood stream. Because THC can remain in a person’s system for days after it is consumed, the only other result would have meant that thousands of medical marijuana patients would be driving illegally simply for having used their medicine hours or days earlier.
Rodney Koon — a medical marijuana patient — was stopped while driving and later accused of a DUI because he had THC in his system. He said he had not used his medicine in six hours. The state Supreme Court found that under the Michigan Medical Marijuana Act — which was drafted by MPP — a registered patient cannot be penalized or arrested for the “internal possession” of marijuana, so long as the patient complies with the requirements of the law. The initiative’s protections trump the state’s zero tolerance law for registered patients. The court noted the law does not allow patients to drive when they are under the influence of marijuana.
