Chronic obstructive pulmonary disease needs adjectives: "Guiltless" COPD, "asthma like" and "emphysemal" COPD

The author proposes an extension of terminology of COPD by introducing to certain situations the adjectives "guiltless" (for patient who never smoked), "asthma like" (for patients with symptoms with reversible bronchoconstriction and eosinophilia) and emphysemal COPD. The aim of this proposal is better understanding of certain events in the disease and subsequently proper treatment.
