Wales could be the first part of the UK to ban the use of electronic cigarettes in enclosed public places.
Ministers say they are responding to concern that the devices - which can contain nicotine - normalise smoking and undermine the smoking ban.
Health Minister Mark Drakeford said the aim was to address some of the nation's major public health challenges.
