 A teacher has called for the UK to take "a leaf out of Australia's book" by bringing in stricter laws on vaping.Under new laws in Australia vapes will be available by prescription only.Teacher and union secretary UCAC Chris Shaw added: "They as a country banned vapes for everybody except those on plans from their GPs and that seems to be a sensible way forward."On Tuesday, the UK government said it would close a loophole allowing shops to give free vape samples to children.
