E-cigarettes face new restrictions in the UK

Electronic cigarettes are to be classed as ''medicines'' under new proposals to tighten up the regulation of products containing nicotine.
It means tough new tests for manufacturers producing them, and there will be tighter controls on how they are marketed.
E-cigarettes are designed to replicate smoking behaviour without the use of tobacco, turning nicotine and other chemicals into a vapour that is inhaled.
