I have never smoked cigarettes, except experimentally as a teen. A friend who was with me said my face turned green.
But, both my parents smoked. Mom smoked during all five of her pregnancies
Many of my friends were smokers, including boyfriends. My son's father smoked. When I was 30 I worked in an office without windows with smokers. My issues with congestion started being noticeable around then.
I actually don't think I have COPD since I am not that disabled. The coughing with mucus is very bothersome, but it doesn't prevent me from exercising quite a bit, and I think Yoga helps. Anyway, what I am getting at--I wonder if inhaling 2ndhand smoke, over so many years, caused lung damage, and my symptoms. And I wonder if this could be common with those who have COPD. What about you?
