Nova: Search for a Safe Cigarette

Every year, 420,000 Americans die from the effects of cigarette smoke. In Search for a Safe Cigarette, NOVA gains unprecedented access to tobacco research and manufacturing facilities and asks the question: Can science help create a safer cigarette? Discover how superheated tobacco creates over 45 known carcinogens and how tobacco-specific nitrosomines damage human DNA; then, take a look at the history and the future of "safer" tobacco products.
