I'm not surprised at the THC findings, especially if he was self-medicating. I am surprised that he would be foolish enough to get behind the wheel of a vehicle and attempt to drive home under that type of multiple influences. Medical MJ is legal in the state of Florida, based on the latest review of their laws.
But... self-medicating would also hint that a prescription of MJ wasn't obtained, or so it would seem.
Again, he has a history of poor judgement, so this doesn't surprise me.
Tiger is finished. I think it's time for the fans and the media to move on. And perhaps it's time for Tiger (himself) to move on as well.
