“The Arizona Supreme Court recently agreed to review an appeals court decision that decided drivers who have medical marijuana cards can be prosecuted for driving under the influence if they’re found to have marijuana in their system.  In two cases, defendants who had medical marijuana cards argued they should be able to use their medical marijuana cards as defense like other prescription drugs are used.  But, the District One appeals court disagreed.  The court ruled the medical marijuana law doesn’t provide immunity for patients because it’s not prescribed by a doctor, it’s recommended.”
