Do you think you drive better or worse when smoking? I don't think it makes much of a difference to me. I took part in a research study at Wake Forest Baptist Medical center on the effects of marijuana/driving/balance/sleep deprivation, and during the simulated driving portion, I did not hit any of the barriers that popped up, so I guess they were only testing reaction time.

Here's the results of that study:
