A student project aimed at teaching primary school pupils about the dangers of passive smoking is helping create smoke-free homes.

Pharmacy and Clinical Sciences students from Bradford University have been visiting schools to warn youngsters about the dangers of breathing other people's smoke.

The project is part of an initiative supported by the Bradford District Stop Smoking Service to cut the number of children exposed to smoke.

The team of 12 students has visited 12 primary schools each university semester. So far the group has spoken to about 650 pupils aged nine to 11. They use cartoons, interactive presentations and word games.

Co-ordinator Glyn Owens said: "We talk about the 4,000-plus chemicals in cigarette smoke by using everyday examples, like ammonia in bleach, acetone in nail polish remover and cyanide and arsenic used to bump off people in murder mysteries."

The university students set out the health problems, like triggering allergies and asthma, heart and lung problems and irritating the eyes, nose and throat.

They also encourage children to speak to their parents about making their homes smoke-free which gets them a goody bag and advice for parents.

"The feedback is very positive from parents, teachers and pupils. As a result of the sessions in schools many families have signed up to make their home smoke-free," said Glyn. The project also allows the science students to develop public speaking skills and run a project outside their formal lessons invaluable when looking for a job.

The Telegraph & Argus has been lobbying for a complete ban on smoking in public places since November 2004 under its Clear the Air Campaign.
