Scientists at the University of Ottawa have found that individuals who use marijuana have more signs of respiratory inflammation and lung emphysema in their lungs compared to smokers. This research was published in the Radiology journal.


Scientists analyzed the results of chest computed tomography (CT) scans from 56 cannabis users, 57 non-smokers, and 33 smokers. The data was obtained from October 2005 to July 2020 in Ottawa, Canada.


Compared to non-smokers, CT scans of marijuana users show differing frequencies of signs of respiratory inflammation, such as emphysema, bronchial thickening, bronchial dilation, mucous obstruction, and cardiac nodules.


Consumers of marijuana are 93% more likely to suffer from chronic obstructive pulmonary disease (COPD) compared to non-smokers, while smokers who consume marijuana have a 67% increased frequency of smoking.


A study has found that 38% of marijuana users who participated in the study reported experiencing gynecomastia, a condition that causes pathological breast enlargement in males. Of those affected, 16% were non-smokers.


This study has limitations, as it was not able to clearly distinguish the consequences of smoking from those of using marijuana. Firstly, only 28 out of 56 patients provided information about their daily marijuana intake, with an average of 1.85 grams per day.


Furthermore, out of 56 marijuana consumers, 50 of them also smoke. The author calls for further research.
