Children are getting high on laughing gas in supersize cans sold on Amazon and eBay.
Schools are sending out alerts spelling out the dangers of abusing Smartwhip cylinders – used by caterers for whipping cream. The capsules contain 76 times more nitrous oxide than the small silver ones that litter streets and parks.
Kids inhale the gas from balloons or just straight from the canister. Over half a million aged 16-24 do it but the gas has dangerous side effects and kills five children a year on average.
