Both my parents smoked like chimneys all through my childhood and I got asthma for the rest of my life as a result. My father died of lung cancer. Smoking undoubtedly exacerbated my mother's heart issues and may well have accelerated her Alzheimers. Don't even begin to blather to me that secondhand smoke is harmless.

And, I think it's cruel to subject pets, with them being captive in your environment, to secondhand smoke. It can't in any way be good for them if it downright doesn't give them cancer or respiratory problems.

I wasn’t blathering to you, why would you even think that? I was simply giving my ancectode regarding second hand smoke. Post hoc ergo Propter hoc is the most common logical fallacy and it permeates peoples thinking on just about everything.

Both my parents smoked like chimneys all through our childhood and we did not get asthma for the rest of our lives as a result. My father died of old age in his 80s. Smoking undoubtedly did not exacerbate my mother's heart issues and she did not suffer from Alzheimers her entire life; she died in her 90s.

Bad genes, on the other hand, is an entirely different issue. Don't even begin to blather to me that bad genes do not often also cause some very serious mental issues!

According to the WHO study, secondhand smoke is harmless, BUT no one, to my knowledge, ever suggested that smoking is good for you.
