I do not smoke, but both my parents have smoked for over 50 years now, and they're health has definitely been affected by it. My father has had 3 heart attacks and my mom has had 2 anyeurisms, one of which she had taken care of because it was close to rupturing, and another that is being closely monitored. I do not let them smoke in my house, and when my kids are born, they are not even gonna be allowed to bring cigarettes to the house.
