1.) Riding High: Arizona's Zero-Tolerance Stance on Pot and Driving
Anyone with the slightest hint of pot residue in their blood -- even card-holding patients -- commits a legal foul every time they get behind the wheel. Arizona is one of 15 states that has a zero-tolerance law against driving with any amount of pot in the system. But, in keeping with the state's oddball reputation, Arizona is one of only three states that have both a zero-tolerance driving law for pot and a law legalizing the sale, possession, and use of medical marijuana.
