ATLANTA — Three film companies have drastically reduced smoking in their movies aimed at children and teens, thanks in part to their policies to reduce on-screen tobacco use, a new study says.
Over the past five years, scenes involving tobacco dropped from an average of 23 to one per film for those companies and most of their youth movies had no smoking at all, the researchers reported last week. At movie makers without such policies, the decline was less - from an average of 18 to 10 incidents per film.
Movies are seen as very influential for kids and teens, and studies have found that sway extends to early decisions about whether to use tobacco.
"The more you see, the more likely you are to be open to smoking and start smoking," explained one of the study's authors, Ursula Bauer of the Centers for Disease Control and Prevention.
Health advocates and some doctors' groups have been pushing the film industry to reduce smoking in films. They have taken to watching top-grossing films and counting the number of scenes in which characters smoke, chew tobacco or hold a pack of cigarettes or in which tobacco use is otherwise implied.
An earlier study showed some success, reporting that tobacco use on the silver screen peaked in 2005 and has been on the decline since.
Last year, only about 45 percent of top-grossing movies had tobacco scenes, compared to 67 percent in 2005, according to the new research.
The study, which focused on youth-rated films, looked at the three companies with policies to reduce smoking: Time Warner (Warner Bros.); Comcast (Universal and Focus Features); and the Walt Disney Co. (Walt Disney Pictures, Touchstone, Pixar and Buena Vista.)
Tobacco scenes declined by about 96 percent in those companies' films over the last five years, and most of the youth-rated films had no smoking at all.
For film companies without policies, the number of tobacco incidents dropped by 42 percent. More than 40 percent of their youth-rated films still have tobacco. Those companies include: News Corp. (20th Century Fox and Fox Searchlight); Sony (Sony Pictures and Columbia Pictures); and Viacom (Paramount Pictures, MTV Films and Marvel). Some independent film companies also were analyzed.
At least part of the decline occurred before policies were in place, and outside pressure and even cultural changes may have played a role, the researchers note.
But advocates and some health officials say the results suggest the policies were a major player, and are good for public health without hurting the film industry.
"We know that it's not a hardship for the companies. These movies can continue to be successful and sell tickets," Miss Bauer said.
A spokeswoman for the Motion Picture Association of America had not seen the study, but said all of its members have taken steps to diminish smoking on screen. Since 2007, all put antismoking messages on movie DVDs, and smoking has been a factor in the rating of films.
"Everyone agrees it's a problem that the industry should not be encouraging or glamorizing," said spokeswoman Elizabeth Kaltman.
Two examples of the rating in practice from last year: Smoking was mentioned for the PG ratings for "Furry Vengeance" - a man was briefly shown smoking a cigar - and "Alice in Wonderland" - a smoking caterpillar.
Under a long-standing agreement between tobacco companies and state attorneys general, cigarette makers are prohibited from paying filmmakers to place tobacco products in movies. Tobacco companies say sometimes movie directors or producers use their products without asking permission.
