Watch: Is vaping more harmful than we initially realised?

The BBC reports new lab tests have revealed the majority of vapes confiscated from students at Baxter College in Kidderminster were illegal and unregulated, and contained high levels of lead, nickel and chromium - and some had higher levels of dangerous carbonyls than some cigarettes. Calls for greater regulation on legal vapes and a crackdown on unregulated one have increased in recent years as the government has attempted to strike a balance between promoting the products as a tool to quit smoking and cracking down on young people vaping - a growing problem, with the risk of youngsters becoming addicted to nicotine in the products.
