Regulating electronic cigarettes is important to stop their promotion to non-smokers and youth, according to a World Health Organization (WHO) director.
Dr Douglas Bettcher, Director the Department for Prevention of Noncommunicable Diseases said the rationale the regulation was "to maximize the potential of e-cigarettes and similar devices and minimize the risks of these products."
He added that the organisation also aimed to "prevent the tobacco industry from undermining the great success we have seen in tobacco control, because, let’s face it, the tobacco industry is not a major producer and manufacturer of e-cigarettes and related products."
