Smoking in films 'encourages teenagers to take it up'

Teenagers who watch films showing actors smoking are more likely to take it up, new UK research suggests.

Experts, who made the link by questioning 5,000 15-year-olds, say their findings should prompt a change in film certification so that under-18s are no longer exposed to such images.

Ailsa Lyons of the UK Centre for Tobacco Control Studies discussed her team's findings with film critic Jason Solomons.
