Chest x-ray??? Not my first post, but had to create another username as I forgot my password and apparently there are not 7 letters in the word "physics"...??? Anyway, I have smoked about 1/2 pack of cigs a day for about 18 months now. I really regret this, as it was stupid. Will an ordinary chest x-ray be able to detect the degree of discoloration in my lungs? I'm just curious how much damage I may have caused. Thanks a lot.
