I've been smoke free for 10 years. The youngest son kept having tonsil issues. I took him to a different doctor and he said you don't know why, really. After he proceed to educate me, I stopped and would go outside. About the second time in the pouring, cold rain I decided it was time to review that habit. I stopped and I'm healthier and no more problems with the son's tonsils.
I know if I ever smoke another, it would be game on. I still can't believe the smells I can smell now and the tastes I didn't taste as a smoker. To each their own, I just choose to remove myself from being around it.
