That is patently false. There is only one single risk factor for cancer generally that is bigger problem than smoking unprocessed tobacco - that is smoking processed tobacco. If you charted endemic cancer risk factors in order of risk, with smoking processed tobacco at the top, then smoking unprocessed/organic/raw tobacco would be about 5% away from the top. The next biggest risk factor would be obesity about halfway down the chart (close to smokeless tobacco products like dip, which has a higher specific risk for mouth cancers). Turns out lighting something on fire and inhaling the combusted free radicals is universally a terrible idea, who’d have thunk? Personally I’m amazed that this kind of misinformation still propagates, on Lemmy of all places, sixty years following the surgeon general’s warning.
