Paraseptal emphysema affects the small air sacs of the lungs, which take in oxygen and remove carbon dioxide. Damage to these air sacs creates small holes in the lungs, which affect that gas exchange.

The researchers also found that a subtype of emphysema that affects the outermost parts of the lung, called paraseptal emphysema, was more common among marijuana smokers than tobacco-only smokers ...

Cannabis smokers showed higher rates of paraseptal emphysema and airway inflammatory changes, including bronchiectasis, bronchial wall thickening and mucoid impaction, to name a few.

The radiologist found marijuana users overall — including younger people who hadn't been exposed to as much smoke — had significantly higher rates in particular of paraseptal emphysema, a rare ...

Pulmonary emphysema in (A, B) marijuana and (C, D) tobacco smokers. (A) Axial and (B) coronal CT images in a 44-year-old male marijuana smoker show paraseptal emphysema (arrowheads) in bilateral ...

Paraseptal emphysema is a disease of the small air sacs of the lungs that are responsible for taking in oxygen and removing carbon dioxide, said a study coauthor, Dr. Giselle Revah, a ...

They determined higher rates of paraseptal emphysema and airway inflammatory changes, such as bronchiectasis, bronchial wall thickening, and mucoid impaction, in the marijuana smokers.

Paraseptal emphysema was also more frequently identified in marijuana smokers as compared to the lungs of tobacco-only smokers. Conversely, centrilobular emphysema was primarily visualized in the ...

Paraseptal emphysema, which damages the tiny ducts that connect to the air sacs in the lungs, was the predominant emphysema subtype in marijuana smokers compared to the tobacco-only group.
