The UK vaping market is now huge. It's worth more than a billion a year and there are these vape shops on what feels like every high street. But do we know how many young people are actually vaporising? Ash, Action On Smoking and Health says it's 7% of 11 to 17s - up from 4% in 2020. That's enough to make people quite worried.
Madeleine Finlay speaks to former Guardian health editor Sarah Boseley about the rise in vaping among under-18s and what can be done to discourage more children from taking up the habit. She also hears from Prof Linda Bauld about the impact of vaping on young people. Help support our independent journalism at
