Yea, I also drive high. The way I see it, if you want to be safe, don't drive and smoke (although I still do this <<) and don't drive if you know you won't be able to. I won't drive right after smoking (a half-hour to let it cool off, an hour if my tolerance is down) and I didn't do it when i was still new to smoking. When you want to learn to drive high, start by smoking and going around the block, driving to nearby areas, etc. To learn, then you'll be fine.
