If you can't eat with a pure conscious, then don't, but neither are we to judge our neighbor. For example I take addictive or altering products including herbs of any kind including caffeine. Paul instructed Timothy to take a tiny-bit for his stomach's sake and for the often ailments Timothy had. I choose NONE. (Have lot of alcoholics in the family and seen too many too easily addicted on '1/2 cup' a day.)
