E-cigarettes 'should be banned indoors' and 'may pose threat to foetuses of pregnant women'
E-cigarettes should be banned indoors, the World Health Organization said.
The health body said there must be no more claims that the devices can help smokers quit - until there is firm evidence to back this - and sales to children should stop.
WHO experts warned the products may pose a threat to youngsters and the foetuses of pregnant women.
It said legal steps need to be taken to end the use of e-cigarettes indoors - both in public spaces and in work - because of fears over second-hand smoke.
The WHO warned exhaled e-cigarette vapor could increase the background air levels of some toxicants and nicotine.
E-cigarettes, officially known as electronic nicotine delivery systems (ENDS), carry a risk to those standing around users, a report for the UN organization said.
