Welsh health minister Professor Mark Drakeford said officials were considering a ban in Wales amid fears the e-cigs could “re-normalise” traditional cigarettes and undermine the ban on smoking in enclosed public spaces.
He said: “We are concerned they might act as a gateway to conventional cigarettes. It contains nicotine, it’s highly addictive and you might then find it easier to move on to conventional cigarettes. I want to minimise the risk of a new generation becoming addicted.”
If accepted, the ban could be rolled out across the UK.
The electronic devices, which can contain nicotine, have already been banned in some Welsh cafes and Cardiff’s Millennium Stadium.
Sales of e-cigarettes have boomed in recent years, with supporters claiming they are safer than ordinary cigarettes.
