Good afternoon everyone! Not sure if this is the 'best' place to post this question, but I figured someone here might have some experience w/e-cigarettes. Here's my issue. My 17yr old daughter, a non-smoker, was talked into trying an e-cigarette of a friend's father. He only recently started w/the e-cigarettes and promised my daughter they were only water vapor. Well, immediately following her one time inhaling, she had bad chest pains that lasted all day. The pains calmed down once she ate dinner. But ever since, she has also had a horrible dry cough. Do you think this is merely an odd coincidence, or do you think it could be related, and if so, any thoughts on what can be done to quiet this cough? It's been getting worse since she tried the e-cigarette, and that was almost a week ago.
