Well, I'm an exception to the rule. I'm the type of dude that catches shit in mid air while passing by. Great reflexes. Drive high all the time. Not a single ticket. Never get stopped, never have.
Some day I realize this lucky streak will end but I don't believe it will be because I'm high from weed. I'm really focused while high on weed. More so than sober.
Gonna +1 you here, I'm the same exact way with reflexes and all, I just don't drive while high. EVERYBODY in MN does though, everybody who smokes it on a daily basis, anyway (so it doesn't effect them nearly as much as a n00b smoking then driving.)
It's pretty much standard practice here, and I've never known anybody that I know that does that, to ever get in any sort of accident because of it. It has the same focusing effect on most of them as it does you n' I.
It really does simply come down to tolerance, when you think about it. People smoke so much that, when they toke up a bowl it's like lighting a cigarette or something. There's a calming effect, not debilitating. Except with this stuff I have now, it's pretty debilitating (then again before yesterday I hadn't smoked in a good week or 2.)
