The chemicals created by cannabis varieties are shown to have an effect. But this comes with a caveat that often gets ignored: the delivery method. I also have never seen an amount specified (although I'm sure if I looked more into the linked studies I might find that). Back to delivery methods - you get a lot more THC in your blood stream by using a vape than by smoking a joint. The delivery method used by these mice studies is tubefeeding, which is an even more direct method of getting the chemicals into the bloodstream. The studies on THC/CBD/etc do not imply that the typical use of smoking marijuana would be beneficial. I do remember a study showing that smoking may result in a decrease, but I don't think the results were strongly conclusive. I also believe it had received funding by a pro-legalization lobby group, which means I don't quite trust the weakly-correlated conclusion of the study. E: Although it gets a little lengthy and still misrepresents the article, the most accurate title would be "Cannabis not linked to increase of cancer".
