Also cigarettes are bad for you not so much b/c of the tobacco itself (though it is potentially harmful) but more because of the way it is processed (even "all-natural" cigarettes are processed) to make it more absorbable.

I think that organic unprocessed marijuana is probably equal to organic unprocessed tobacco (though I have no research to back that up), but the marijuana you're going to smoke a lot less of than the tobacco, so it ends up being less harmful to your lungs.

Your brain... that's another story. There is research that says smoking up to five joints a week can benefit your brain, but any more than that, and your memory and attention will be negatively affected.
Most Cigarettes contain radioactivity, because of the presence of Polonium 210 in the soil that it is grown in. This is verified by reliable studies and research, including former Surgeon General C. Everett Koop:

In 1990, then Surgeon General C. Everett Koop declared on national television that 90% of all smoking-related cancers were caused not by tar or any of the other factors we normally think of, but radioactivity.The Radioactive Ciggy (The Anthropik Network)

This can lead to cancer, not just of the lungs, but the kidneys and other organs as well.
