Seems like this is going to be happening more often. You're on a drug that has side effects. You spend a good portion of your time driving back and forth to work. Only a matter of time before you have some sort of episode while driving. The guy in question, while on the stop-smoking drug Chantix, had his eyes roll back in his head as he drifted off the road. The non-profit institute Safe Medication Practices linked the drug to more than two dozen highway accidents.
Wait....there's actually a group that tracks that now? I wonder if they have a website....Yes they do!
