That's fricking BS, and that's coming from a *mild, now* smoker. My parents used to smoke in the house with me all when I was growing up. I was in so many sports, and ran around so much, and lived in a smogless town - yet - I developed exercise asthma....And even though I had to run all the time for sports, I wasn't a good
long distance runner...however...as soon as I moved out of the house, I took up running as excercise and suddenly had no real problem running three miles six days a week.
So...Bullsh**!!!! LAME!!!!! EVIL!!!
*this public service announcement brought to you by a smoker*
*Although I don't deny the evils of pharmeceutical companies, I just think in this case it really doesn't apply like they're saying it does.
