Of course, I'm sure the stoner brigade can produce a plethora of studies claiming that weed is a fucking miracle cure-all with no downsides whatsoever, written by the same kind of biased researchers that produce studies showing that burning shit-tons of coal is great for the environment.
Yeah, because the same "stoner brigade" you just derided for being lazy fucks are also a well-heeled special interest lobby like the coal industry.
while I never was a full-time stoner myself, I did smoke enough to know that I sure as shit wouldn't have felt comfortable driving on it (or doing anything else that required concentration).
Of course, no stoner I've ever talked to claims that everyone can drive at any level of high-ness, but rather derides the idea that you can set a uniform standard like you can for BAC. Pot doesn't work the way alcohol does; it influences brain activity in much more subtle ways, and it effects everyone a little bit differently. Most importantly, it doesn't impair your ability to judge if you're capable of driving.
