Health – Despite the small sample size, findings suggest marijuana smokers saw additional lung effects over and above tobacco. Smoking marijuana can damage the lungs and airways more than tobacco, according to a Canadian study released Tuesday (15.11.2022).     

Researchers from the University of Ottawa and Ottawa Hospital examined chest X-rays of 56 cannabis smokers, 57 non-smokers and 33 people who only smoked tobacco between 2005 Y 2020.

They found higher rates of airway inflammation and emphysema, a chronic lung disease, among regular cannabis smokers compared to regular tobacco-only smokers and non-smokers..

Giselle Revah, radiologist at Ottawa Hospital, He said the higher rates of inflammation and disease among marijuana versus tobacco smokers could be related to differences in how the two substances are consumed..

“Marijuana is smoked without a filter, while tobacco usually leaks”, He said. “When you smoke unfiltered marijuana, more particles reach the airways, settle there and irritate the respiratory tract”, he explained.

further, he added, in the case of marijuana, puffs are usually “larger and the smoke is retained longer in the lungs which can cause greater trauma” in those organs.
