　　 Hollywood's Smoke Alarm

　　Onscreen puffing is recruiting a new generation of kids.

　　The American screen has long been a smoky place, at least since the 1940s, when Bette Davis and Paul Henreid in Now, Voyager showed how to make and seal a romantic deal over a pair of cigarettes that were smoldering as much as the stars. Today cigarettes are more common on-screen than at any other time since midcentury. 75% of all Hollywood films show tobacco use, according to a 2006 survey by the University of California, San Francisco.

　　Audiences, especially kids, are taking notice. Two recent studies, published in the Lancet and Pediatrics, have found that among children as young as 10, those exposed to the most screen smoking are up to 2.7 times as likely as others to pick up the habit. Worse, it's the ones from nonsmoking homes who are hit the hardest, perhaps because they are spared the dirty ashtrays and musty drapes that make real-world smoking a lot less appealing than the sanitized cinematic version.

　　Now the Harvard School of Public Health (HSPH)-the folks behind the U.S. designated-driver campaign-is pushing to get the smokes off the screen. "Some movies show kids up to 14 incidents of smoking per hour," says Barry Bloom, HSPH's dean. “We’re in the business of preventing disease, and cigarettes are the No. 1 preventable cause."

　　If there's one thing health experts know, it's that you don't influence behavior by telling people what to do. You do it by exposing them to enough cases of people behaving well that it creates a new norm. What made the designated-driver concept catch on in the 1980s was partly that Harvard and the ad agencies it worked with persuaded TV networks to slip the idea into their shows. There's a reason a designated-driver poster appeared in the bar on Cbeers, and it's not because it made the jokes funnier.

　　"The idea appeared in 160 prime-time episodes over four years," says Jay Winsten, HSPH's associate dean. "Drunk-driving fatalities fell 25% over the next three years."

　　Harvard long believed that getting cigarettes out of movies could have as powerful an effect, but it wouldn't be easy. Cigarette makers had a history of striking product-placement deals with Hollywood, and while the 1998 tobacco settlement prevents that, nothing stops directors from incorporating smoking into scenes on their own.

　　In 1999 Harvard began holding one-on-one meetings with studio execs trying to change that, and last year the Motion Picture Association of America flung the door open, inviting Bloom to make a presentation in February to all the studios. Harvard's advice was direct: Get the butts entirely out, or at least make smoking unappealing.

　　A few films provide a glimpse of what a no-smoking-or low -smoking-Hollywood would be like. Producer Lindsay Doran, who once helped persuade director John Hughes to keep Ferris Bueller smoke-free in the 1980s hit, wanted to do the same for the leads of her recent movie Stranger Than Fiction. When a writer convinced her that the character played by Emma Thompson had to smoke, Doran relented, but from the way Thompson hacks her way through the film and snuffs out her cigarettes in a palmful of spit, it's clear the glamour's gone. And remember all the smoking in The Devil Wears Prada? No? That's because the producers of that film kept it out entirely-even in a story that travels from the U.S. fashion world to Paris, two of the most tobacco-happy places on earth. "No one smoked in that movie," says Doran, "and no one noticed."

　　Such movies are hardly the rule, but the pressure is growing. As Harvard closes in from one side, a dozen health groups including the American Medical Association are calling fox reduction of smoking in movies and on TV; and 41 state attorneys general have signed a letter seeking, public-service ads at the beginning of any DVD that includes smoking. Like smokers, studios may conclude that quitting the habit is not just a lot healthier but also a Lot smarter.
