You really shouldn't drive high to begin with anyways. Your judgement definetly becomes impaired while you're high. That's cool if your not putting anyone else in danger but if you drive around stoned and something suddenly happens where you need to act realy quick you might not respond fast enough. No, it's not gonna be like the above the influence commercial where you keep driving when the girl pulls out infront of you but lets say a kid jumped infornt of the car all the sudden. Would you be able to slam on your breaks? I wouldn't. Maybe some people can. But I know I wouldn't do it unless I really had to.
