The number of Hollywood films showing on-screen smoking is back up to the levels of the 1950s, according to a new study by California-based researchers.
The study claims that nearly 80 percent of films rated for young audiences include scenes in which characters smoke and concludes that the reason why nearly half of teenage smokers in the U.S. try cigarettes can be linked to on-screen smoking. On the basis of their findings, the researchers have called for an adult rating for all films which depict tobacco use.
