Evaluation of: Pell JP, Haw S, Cobbe S et al. Smoke-free legislation and hospitalizations for acute coronary syndrome. N. Engl. J. Med. 359, 482-491 (2008). A study is published in one of the world's most reputable medical journals and is rated a "must read" by the prestigious Faculty of 1000 [101] , yet described in the BBC News Magazine--even before it is published--as looking like "over-hasty, over confident research" [102] and ranked among "the worst junk stats" of the year by a Pro Vice Chancellor of Oxford University. Amid scenes reminiscent of the AIDS conferences of the 1980s, researchers on their way to hear the initial presentation were forced to cross a line of angry pickets waving "Junk Science" placards. The issue is controversial enough to provoke the 'First World Congress on Smoking Bans and Lies' in January 2009, and it is precisely the rapidly growing weight of evidence, rather than the lack of it, that has made it a battleground in an emerging clash between the public health community and those who deny that secondhand smoke kills.
