I also had a pneumothorax when I was 16 or 17.
Yes, you can get them by being tall & skinny. Smoking (anything) doesn't help.
Neither did the bottle tokes & hot knives I was doing at the time.
Oddly enough, mine never really hurt, it just gurgled when I took a deep breath. I even flew to Europe for 10 days with it.
I didn't heed the doctor's advice and it occurred again.
He gave me a great detailed explanation of how they cut open your chest and get rib spreaders to make room to work so they can cut out part of the lung...
I quit smoking everything, right then and there!
I'm old, this was 20
years ago now!
Ale is cheaper than hash anyway.
I was lucky. I never had to go under the knife. But it was close.
I was at home, feet up on the couch for 2 weeks watching tv & reading.
My parents felt so bad, they even went out at bought a VCR (about $600 back then) so I could watch movies.
My sister has the VCR and its still running fine!
