I smell a fish.
Chronic obstructive pulmonary disease (COPD) is a general term, with emphysema a term usually applied to heavy smokers. True premature COPD is not common and sometimes occurs in families with a deficiency of alpha-1-antitrypsin (along with liver problems).
But just having scars on your chest x-ray is totally inadequate to make a diagnosis of emphysema -- especially in a nonsmoker. Could be from prior infection, occupational exposures, etc. Other tests, such as pulmonary function tests, are needed. If you doctor has not addressed those issues, ask again. If you don't get satisfaction I'd see a pulmonologist.
But, you are right - second hand smoke is nasty stuff.
