I was just stating. The amount usually doesn't impact your abilities to a drastic level (due to it being a short amount of time)
It should be how often and how long they smoke. If they smoke throughout the day and smoke enough to get high (my aunt) they wouldn't be able to raise a family. (My aunt can't. Her only son, my cousin, lives with our grandparents)
Also smoke and most anything you breathe in throughout the day is bad for your lungs. So I will not disagree with that. Smoke does worsen it faster then a lot of things. But it's no worse then smoking a cigar or cigarette.
