A study in the journal Radiology claims that marijuana smokers are more likely to develop emphysema. During this, the volume of the alveoli increases in the lungs due to the destruction of the membranes between them. With this disease, it is difficult to breathe out. In addition, the lungs become lifeless. Scientists suggest that the results of the study could be due to the fact that marijuana smoke enters the lungs unfiltered.
Scientists already know a lot about the effects of cigarettes on the lungs, unlike marijuana. Study author Giselle Reva suggested that smoking “weed” accumulates many times more particles in the lungs than a regular tobacco cigarette. To test this claim, she and her colleagues compared CT scans of 56 marijuana smokers with 57 non-smokers and a group of 33 tobacco smokers.
They found that three-quarters or 75% of marijuana smokers developed emphysema. But tobacco connoisseurs got a lower result – 67%.
Dr. that the results were unexpected. The reason for this is that some people have had extensive experience with both types of smoking. But the significant effects of marijuana on the lungs are only now known.
At the moment, they plan to conduct additional studies.
