“Tobacco is addictive; by many criteria more so than heroin and cocaine. There was a reason people would, as the 1940s ad put it, “walk a mile for a Camel.” More people have died of tobacco than in all of World War II. According to the World Health Organization, smoking kills three million people every year worldwide. This will rise to ten million annual deaths by 2020—in part because of a massive advertising campaign to portray smoking as advanced and fashionable to young women in the developing world. Part of the success of the tobacco industry in purveying this brew of addictive poisons can be attributed to widespread unfamiliarity with baloney detection, critical thinking, and the scientific method. Gullibility kills.”
