When you smoke unfiltered marijuana, more particles reach your airways, settle there and irritate them. Moreover, continues the radiologist, “People generally take bigger puffs of marijuana and hold the smoke in their lungs longer, which can lead to more trauma to those air spaces”. The authors of the study point out that some of the cannabis smokers also smoked tobacco.
In addition, some chest X-rays have also not yielded conclusive results, which means that further studies are needed. Especially since the study on a fairly small sample. However, the researcher points out, there is very little research on the health effects of cannabis, as it is banned in most countries.
