Cannabis and tobacco smoke are not equally carcinogenic

Very interesting paper:

I like the last paragraph....

It should be noted that with the development of vaporizers, that use the respiratory route for the delivery of carcinogen-free cannabis vapors, the carcinogenic potential of smoked cannabis has been largely eliminated

This seemed kind of important for whether cannabis causes or cures cancer:

Furthermore, compounds found in cannabis have been shown to kill numerous cancer types including: lung cancer [9], breast and prostate [10], leukemia and lymphoma [11], glioma [12], skin cancer [13], and pheochromocytoma [14]. The effects of cannabinoids are complex and sometimes contradicting, often exhibiting biphasic responses. For example, in contrast to the tumor killing properties mentioned above, low doses of THC may stimulate the growth of lung cancer cells in vitro [15].

Low doses of THC may stimulate cancer? Someone needs to study this and come upon some numbers. Last thing I want is to underestimate how much THC is needed for its cancer fighting properties.

The elephant in the room is that researchers have looked for evidence that smoked cannabis promotes cancer and have been unable to find any. The speculation is that any carcinogenic properties are offset by the known tumour-inhibiting properties of cannabis. This is why isolating a single compound of cannabis and making a drug from it will not necessarily have the same effect as consuming cannabis whole. We know for sure that CBN inhibits THC, for example, but what no one has determined is exactly what are the relationships of the various compounds, and there are a lot of them.

This will hopefully change when it becomes federally legal. We really need clinical trials for info like this. Even the cancer fighting properties have been shown in lab - vitro but who knows if it's the same for humans and if so at what levels. I found the nicotine information interesting. I think it's obvious there are differences (400,000 deaths linked to cigarettes in the US, 0 linked to MJ) this paper sheds some light on the differences

Here is the paper they cited for that info, unfortunately I don't think the full text is free:

Looks like it was done in 1943?!
