Hmm, I don't think this thread applies to me since I only bike for leisure and socializing. Besides, I am not a drinker. But some of my riding colleagues say that they sometimes go on tours with drinking sessions in the destination. So what happens at the end of the day is that they ride on their way back home. The only safety precaution is their sheer number since they are an organized group of more than 50 cyclists. Even at night, they have no apprehension in riding.. drunk... because of the peer support.
