Seriously I used to delivery Italian food to people ripped off my ass. The paranoia keeps you on the edge of your seat and paying attention. In fact I drive better blazed because I pay much more attention to the road and not everything else. If you have serious delayed reaction time from weed smoking you don't smoke enough to be driving high. Driving high is an absolute non issue for us heavy smokers who can handle it.

Don't get behind the wheel and drive if you get all wacked out on weed once in a blue moon*
