Smoke ban in films

The government is contemplating a ban on any depiction of smoking in movies. A ban for commercial advertisements for tobacco products is already in place. But the concerns are that banning such images in films is undue interference with artistic freedom, as articulated by many in the government as well as the film industry, including actor Amir Khan. It makes an interesting case for the limit of free speech, and the difference between the protection of commercial and artistic speech, if any. The ban is even more controversial because the government has issued the regulation on the basis of a law which was aimed only to regulate commercial advertisement of tobacco use.
