So far the evidence seems to show that smoking and vaping cannabis does not have nearly the potential for lung cancer that tobacco smoking does. It is associated with various respiratory ailments (under heavy use). And it may have a slight protective effect against some cancers. As usual, more and higher-quality data would help elucidate the source of the protective effects. |
