i love smoking and driving. but one time, (back when i was doing coke still) i had just finished up the last of a gram and got out on the highway. a friend and i were in the truck. he lights up a fat ass blunt, and i hit it a few times. i'm going like 70 mph and all of a sudden, my vision goes black and i start to "faint?" while driving. my buddy's just sittin' over in the passenger seat, not noticing a thing, until i start to try and pull off the road and come to a stop with half my truck still sitting in the fast lane. he about shit himself when the car behind us almost ate my back bumper. that's the second time that shit's happened while i was smoking/blowing at the same time. guess it's from the uppers and downers fighting each other. i dunno, but it was definitely crazy shit. anyhow... yeah, i'd smoke on the way.
