This comparison between smoking a cigar once in a while (which you don't inhale cigars anyway) and alcoholism has got to end.
What I'm hearing is that, "Hey, that guy over there is an alcoholic and he quit smoking and now he smokes a cigar once a year on the golf course, so I GUESS THAT MEANS I CAN DRINK IN MODERATION."
Alcoholics cannot drink in moderation because either their systems have been physically overwhelmed on a molecular level by long-term alcohol use or they are genetically incapable of processing alcohol normally, but either way they can never go back and drink safely.
