Radioactive polonium is the really worry with tobacco use.

    Compare the 12,000 at the Wikipedia link to the 1.6 million here: http://www.who.int/cancer/prevention/en/ http://www.who.int/cancer/prevention/en/ From those numbers, the polonium is not a primary concern.

    It's not entirely true. Even though the vast majority of tobacco-related cancer deaths may be caused by polonium, cancer deaths are still only around a third (iirc) of total tobacco deaths.
