Concerns about teen smoking have prompted the movie industry to consider smoking in determining a movie's rating.
That means "PG-13" films with tobacco scenes -- could be rated "R."
It wasn't a big issue years ago -- when smoking was more prevalent in society.
The industry reports... movie makers have cut smoking scenes by almost 10 percent in the last two years.
But, anti-smoking groups... the American Medical Association, even cigarette-maker Phillip Morris, have urged the industry to show less smoking. That's based on research that suggests teens and preteens are highly influenced by what they see.
The American Cancer Society issued a statement calling the industry's move an important first step.
It also says it will continue to monitor and push for a full ban on smoking scenes in movies marketed to children
