Driving drunk is obviously stupid, but having a single 12oz can of beer with lunch or dinner, I'm not going to judge anyone for that. Personally, I think it's not a big deal, but each person needs to make their own choice based on their ability to handle alcohol. That's why they passed such a black and white law, they don't want people trying to make reasonable decisions. So now there's no need to even think of having even a single beer, not worth risking deportation.

Here's some food for thought for those of you that are into oral hygene:

Listerine Antiseptic" published in the July 1985 issue of The Police Chief (p. 70). Seven individuals were tested at a police station, with readings of 0.00%. Each then rinsed his mouth with 20 milliliters of Listerine mouthwash for 30 seconds in accordance with directions on the label. All seven were then tested on the machine at intervals of one, three, five and ten minutes. The results indicated an average reading of 0.43 blood-alcohol concentration, indicating a level that, if accurate, approaches lethal proportions. After three minutes, the average level was still 0.020, despite the absence of any alcohol in the system. Even after five minutes, the average level was 0.011.

Cheers!
