Smokers in their teens are not put off cigarettes by graphic photos on the back of packs, according to researchers at the University of Stirling. The text-only warning were found to have even less of an effect.
The Tobacco Journal's research into the relationship between teenagers and anti-smoking pictures on cigarettes packets has shown why graphic images need to be on both sides of the packaging, a health charity has said.
Alison Cox, head of tobacco policy for Cancer Research UK, explained:
"This research boosts the extensive evidence that picture health warnings are very effective in reminding smokers about the dangers of tobacco," she said.
"We know that well-placed picture warnings work and discourage young people from starting to smoke so we're delighted that the European Parliament will vote on legislation for picture warnings to appear on both sides of cigarette packs."
"UK law requires picture warnings to appear only on the back of the pack. This research shows why European legislation is so important."
Online journal Tobacco Control carried out two surveys of over 1,000 11 to 16-year-olds in the UK were questioned about their response to warnings in 2008 and a further 1,000 were questioned in 2011.
Over half of the teenager in both surveys (68% and 75%) had never smoked and 17% and 22% had experimented with cigarettes.
One in 10 of the teenager questioned were regular smokers - they lit up at least once a week.
Half of those questioned in both surveys said they had 'often' or 'very often' noticed the warnings on packs, and around one in five had read them very often or looked closely at them.
The teenagers' ability to recall images depicting diseased lungs, rotten teeth and neck cancer, remained below 10% while three text warnings on the back of packs with no supporting images were recalled by less than 1% in either survey.
