This print ad from 2008 is one of the more potentially offensive anti-smoking ads we've seen, but it definitely paints a vivid picture. The text reads: "Terrorism related deaths since 2001: 11,337. Tobacco related deaths since 2001: 30,000,000. For help call 0800 ASH INFO." The contrast to one of the greatest tragedies in recent history helps drive the point home.
