I have recently recovered from a partially collapsed lung which I have had for a week I did not smoke while I had my collapsed lung but is it OK to smoke now?

If you had one collapsed lung, and you probably suffered through that, why would you want to damage the other one by smoking again ? Don't you think you are better not smoking ?

No, its never OK to smoke. If you must, get the patch... you have already went through the hardest time of not smoking and I believe that the nicotine has left your blood stream... so all you really have is the mental addiction to fight.
