For years scientists at Philip Morris USA have studied how the human lung delivers a highly addictive chemical, nicotine, to the smoker's brain.

A team of Philip Morris engineers and scientists is working on a new design for a hand-held inhaler to treat a variety of ailments, including smoking-related lung disease. The product, called Aria, arose from a failed effort to invent a safer cigarette alternative.
