Given the situation, he probably wasn't high at the time. Simply b/c of the timeframe of leaving the stadium, heading out to Shannon's, and then going to a diff. spot, he would've had to light up in the car. They'll prob. find pot in his system just not from that night. People light up in cars all the time, as well as in the parking lot before pulling out. I don't know many people who keep weed on them who don't take every chance to smoke it. It was in his rental car, that he had just gotten a couple days before. In my experience, the people who have weed with them in a car, will not hesitate to smoke, especially once they're already buzzed. I would be surprised if he hadn't smoke some. That would be the only way, he couldn't light it while driving. Sure he could have. It isn't a difficult procedure.
