I can appreciate what you are saying. I wouldn’t encourage any of my 13 grandchildren to take up smoking..I think some of those that get cancer are predispositioned to it...My sister is 80 and has been smoking since she was 13. She has no breathing problems or needs oxygen...I also started at 13. I am not bragging just saying for many long time smokers without problems. My family has a predisposition to diabetes, 2 of my sons, a niece are diabetes...My mother told me when I started to have kids, diabetes seems to skip a generation and my neice was the first female to have it..My husbands family have a predisposition to heart trouble....he died at 51 and 2 of my sons have cardiac problems...its always good to know the family history when it comes to where the weakness in the dna is...
I am sorry for the gentleman you talked with, Your friend was being given oxygen via the mask. with moisture to keep the lungs moist....(Not too many smokers in the family, one of the son’s never smoked legal cigarettes, his brother quits periodically....the other 3 are non smokers
