Long-term cannabis use damages lungs, but in a different way to tobacco
Smoking cannabis leads to lung damage, but in a different way to tobacco, new University of Otago research has found. Study co-author Professor Bob Hancox says until recently, it was assumed that cannabis would have similar effects to tobacco, but this does not seem to be the case.

"Prolonged cannabis use leads to overinflated lungs and increased resistance to airflow compared to tobacco and may also reduce the amount of oxygen extracted from breath."
At least it doesn't give you cancer, though?
I think it sounds scarier than it really is, nobody's going to the hospital for this (probably).
