Terrie Hall, who starred in Arnold's brutal national anti-smoking campaign for the Centers for Disease Control and Prevention, died this week in North Carolina. The image of Hall hiding the ravages of smoking-induced cancer with a wig, false teeth and a scarf is pretty harrowing, and the same can be said for her artificial voicebox. Those get used a lot in anti-smoking ads, but there's always something heartbreaking about them. I often wonder if people like Terrie are being exploited, if their real suffering should be harvested for a marketing effort, even one that's relevant to their condition. But the CDC says the campaign, called "Tips From Former Smokers," prompted 100,000 people to quit."She was a public health hero," CDC director Dr. Tom Frieden said of Hall. "She may well have saved more lives than most doctors do." Hall was 53.
