Mark Drakeford: E-cigarettes 're-normalising' smoking
Health Minister Mark Drakeford said he fears that electronic cigarettes are "re-normalising" smoking and believes there is a case for tighter laws.
He told BBC Wales' Sunday Politics that he was very anxious about the devices.
But he did not dismiss claims that e-cigarettes may help people quit smoking.
Legislation is going through parliament to ban their sale to under-18s in England while a vote in the assembly on Tuesday would extend the ban to Wales.
