Personally,
What he said. I'd be a lot tougher on people with BAC over 0.15, too, which research I've read says are the people who are really killing us out on the roads. (Of the drunks, that is: there are plenty of traffic fatalities, the majority of them, caused by sober drivers.) I don't believe I said drunk-driving laws are bad; I don't believe they are. I think a number of them are badly written, they are poorly enforced, and there are better laws which need to be written. And aiming at criminalizing ever-lower BAC levels is NOT the best way to save lives on the road...although it is a great way to get to de facto Prohibition.
Steve, here I made it clear: I'm not denying that alcohol is a drug, I'm saying that alcohol has been effectively stigmatized as a "drug," i.e., the equivalent of illegal "street drugs" like marijuana, LSD, or cocaine. That kind of equivalency is stuffed into things like the D.A.R.E. program. My wife tests drugs for a living; some would say I do the same thing. That's ridiculous, our jobs are not equivalent at all (she's much better paid for hers, for instance...). What is needed is another word or phrase. Alcohol and nicotine and caffeine (and...any others? I was being facetious with theophylleine) are a separate class, they need another word.
