I don’t think the two are comparable. An alcoholic will often abuse his/her loved ones (if only with negligence), while smokers do not.”
Smokers DO abuse their families. The tragedy is that they might not recognize the abuse they are inflicting until a family member comes down with a respiratory ailment. The other abuse they inflict is the tzaar they cause their loved ones as they slowly die from their self-inflicted lung cancer, emphysema, stomach cancer, throat cancer, and lip and tongue cancer. If you do not believe that this abusive behavior, there is nothing to talk about. And lest you compare it to people who die from overweight issues, at least the obese are not causing their family and friends to “catch” an illness from them. In some cases, yes, you will see wight problems in a family, but it is a reversible machlah. Once smoking has done its damage,there is not much to do about it, except suffer and die a slow and painful death.
