Some time ago, I had an interlock on my car. If there was any alcohol in my system, I could not start my car. On one occasion, I drank a couple of O'Douls, and it did not register. It was supposed to be sensitive to .001 BAC. However, I had some avon lip balm that registered something ridiculous. I don't advocate NA beer, but I think the danger is in the psychological effects, rather than physical. I don't doubt that it can trigger cravings. I'll bet that those microbrewed rootbeers that come in brown bottles could be a trigger as well. I remember the first time I tried to quit drinking. I went to the store looking for alternative beverages, and everything I came home with was in a beer style bottle.
