Ok Arlos, here's the deal. I used to smoke weed, and many people here probably remember this. Marijuana is a powerful high. I don't care if people make the claim that it just gives them the munchies and mellows them out. Bullshit. THC is a powerful, mind-altering drug, and it scares the crap out of me knowing that if marijuana became legalized that millions of people will get behind the wheel and drive while being stoned. We have enough problems and fatal car crashes every year because of drunks behind the wheel... let's not exacerbate that problem by throwing stoned drivers into the mix.
Yes, THC *can* have positive medicinal effects on patients dealing with aids and glaucoma, but let's be real here... you know as well as I that people will use it as an excuse to get high legally.
See, now that's a reasoning I can respect and understand. I can even agree with it to a certain extent. I would absolutely support making the DWI laws a lot harsher at the same time pot was legalized, to make sure that anyone who got completely blotto and drove got the book thrown at them.
There is a difference, however, between completely stoned and lightly buzzed, much the same way as there's a difference between having 1 beer and having an entire bottle of JD. (if we're looking at extreme differences here). 1 beer will not put anyone but the smallest of people over the legal alcohol limit, and thus is legal to drive with. Similarly, someone who only smokes a little bit of pot will not be significantly impaired, if at all.
Actually, numerous studies have found that alcohol is vastly worse for driving performance than pot is, including a study done by the CHP in the 80s titled . Here's a link to one such study:

They found, among other things, that even someone who'd smoked 3 joints in a row, and had a correspondingly high concentration of THC in their bloodstream performed on average exactly the same as someone with a blood alcohol content of 0.07%, which would be legal in California.
Now, I'm by no means advocating getting stoned and going driving. No responsible person will get completely stoned and go drive somewhere, no more than they'd get drunk and do so. So, in any case, we know alcohol is far worse for impairing driving, especially in high doses, than is pot. I don't believe that legalizing pot would appreciably increase the number of accidents we currently see, especially given the emphasis on stopping DUIs that we see in the media, which has cut down drunk driving by a significant margin.
