The World Health Organization (WHO) and the American Heart Association (AHA) have joined the chorus of groups calling for tighter regulation of e-cigarettes, which have grown into a $3 billion global industry.
The use of e-cigarettes are becoming increasingly popular. In a report released in July, the WHO noted that in 2012 an estimated 7% of individuals older than 15 years in the European Union had tried these products, and about 1% were regular users. In addition, nearly half of US smokers reported having tried the devices, but only 4% were regular users.
