Smoking is not healthful... No argument there.
Alcoholism destroys marriages and whole families, wrecks careers, kills innocent bystanders with DUI, drives people crazy....
Cigarettes are lightweight when compared to alcohol, especially when you look at the collateral damage it causes.
That one would disqualify a sponsor who expresses concern about a newly sober person drinking NA beverages for seemingly all the wrong reasons and with virtually no insight on the issue... because said sponsor smokes... leaves me wondering.
