I had to sign in just because of this. Joined the army and went to basic at 18yrs old. But before i could finish had an infection in both lungs plus both ears and was medically discharged. For some reason i wasnt feeling better after months so i went to the doctor, they checked my lungs and told me that they looked like a 50yr old who has smoked 2 packs a day all his life even though i have never done drugs or smoked. They even said that i might have to be put on those air respirators or whatever there scientific name was agian by the age of 30. Glad though as i am 25 and have been getting better over the years. Hope everything works out for you.

This is why I hate people who smoke in the presence of others. It's been proven that second-hand smoke is worse than first-hand smoke, so even if you don't go near cigarettes, you can still get lung cancer from second-hand smoke because some inconsiderate ass keeps puffing on the things in your vicinity.
