I agree with Bravo6 100%. If it's documented in your service records that you were busted for smoking pot or boozing while driving, you can't do anything about it. There is a big difference between sipping the communion wine, a single glass of fine wine with a gourmet dinner, in comparison to over indulging. Additionally, if you are taking any meds that explicitly say to avoid alcohol, you better heed the warning. It is there for a good reason, not about what's ethically accepted, but you are placing your health or life on the line if you ignore it.
