CHICAGO -- The First Amendment, which guarantees freedom of speech and freedom of the press, takes the view that the people should dictate to the government, not the other way around. But no one told a group of 32 state attorneys general, who have taken it upon themselves to instruct the film industry on the appropriate content of movies.
This time, the cause is not raunchy sex, foul language or blood-spattering violence. It's cigarettes. Many experts think that when actors puff away, they cause teenagers to do likewise. One study went so far as to say that 38 percent of all kids who acquire the habit do so because of the influence of films. So all these state government officials want filmmakers to stop depicting tobacco use.
They evidently have had an effect. Not long after the attorneys general sent a letter requesting action, the Motion Picture Association of America agreed to consider smoking in determining each film's rating. "Depictions that glamorize smoking or movies that feature pervasive smoking outside of a historic or other mitigating context" would run afoul of the ratings board.
The MPAA didn't go as far as demanded by some anti-tobacco groups that want to slap an R rating on just about every film in which actors light up. But it accepted the basic principle that public health lobbyists and politicians should have a big role in deciding what people will see.
It's hard to fully credit the notion that kids start smoking just because they see Scarlett Johansson doing it. Steven Milloy, who is the publisher of the Web site JunkScience.com, points out that adolescent smoking has declined even as onscreen smoking has increased.
The studies themselves are not as damning as they purport to be. They indicate that kids who watch more movies with smoking are more likely to smoke. But a correlation does not necessarily show a cause.
It may be that kids see a star light up and rush out to imitate him. Or it may be that teens who are inclined to smoke anyway are also inclined to see the sort of movies that feature smoking.
Michael Siegel, a physician and professor at the Boston University School of Public Health, believes the studies greatly exaggerate the impact of tobacco in films. "It is simply one of a large number of ways in which youths are exposed to positive images of smoking (which includes advertisements, television movies, television shows, DVDs, Internet, music videos and a variety of other sources)," he told me in an e-mail interview.
Putting an R rating on smoky movies probably wouldn't do much to reduce teenagers' exposure. Some 75 percent of new releases that feature smoking are rated R - and a lot of them are accessible even to preteens. In one survey of kids in grades five through eight, only 16 percent said their parents never let them see R-rated films.
Dr. Siegel points out that applying R ratings to films just because they feature full-frontal shots of cigarettes may backfire. Parents anxious about sex and violence may stop paying attention to the rating system once it factors in smoking. So you could end up with more kids seeing films with smoking.
If the MPAA were responding to the clear preferences of parents, this change might be merely dubious. In this case, though, it acted only after getting overt pressure from state governments - which have no more business determining what appears on movie screens than they do in deciding what goes into Judy Blume's next novel.
The MPAA's response validates the politicians in their intrusions and beckons them to find new ways to regulate art and other matters that are supposed to be exempt from their control. A shame it didn't give the attorneys general a simpler, better response: Snuff this.
