I think the idea of forcing a bunch of businesses to have to pay to get permits to get patios for people to smoke on, giving tickets to those who break the law, and further vilifying an act so voters will keep passing more and more tax on it sounds like its worth fudging facts here and there. In Phoenix, why is a pack of cigarettes $5.25 on the res, but $7.09 and higher everywhere else? The difference is tax, tax they keep passing because voters are like, "Cigarettes are so bad, make them pay more taxes." So are they completely harmless? Probably not, but I think these reports talking about how second hand smoke kills are probably fudged a lot because its lucrative.
Oh yes. It is quite obvious that the research groups are all getting to chip in on the government tax money. They are no doubt getting the money handed to them under the table.
Why not, global warming was found to be highly fudged. From what I understand there was a lot of money to be had from installing filters on factories to reduce pollution and the taxes for cleaner airs.
