E-cigarettes gain ground in China

Beijing: With its slim white body and glowing amber tip, it can easily pass as a regular cigarette. It even emits what look like curlicues of white smoke.
The Ruyan V8, which produces a nicotine-infused mist absorbed directly into the lungs, is just one of a rapidly growing array of electronic cigarettes attracting attention in China, the United States—and the scrutiny of health officials.
Marketed as a healthier alternative to smoking and a potential way to kick the habit, the smokeless smokes have been distributed in swag bags at the UK film awards and hawked at an international trade show.
Because no burning is involved, makers say there’s no hazardous cocktail of cancer-causing chemicals and gases like those produced by a regular cigarette. There's no secondhand smoke, so they can be used in places where cigarettes are banned, the makers say.
Health authorities are questioning those claims. The World Health Organization issued a statement in September warning there was no evidence to back up contentions that e-cigarettes are a safe substitute for smoking or a way to help smokers quit. 
It also said companies should stop marketing them that way, especially since the product may undermine smoking prevention efforts because they look like the real thing and may lure nonsmokers and kids. 
“There is not sufficient evidence that (they) are safe products for human consumption,” Timothy O’Leary, a communications officer at the WHO’s Tobacco Free Initiative in Geneva, said.
The laundry list of WHO's concerns includes the lack of conclusive studies and information about e-cigarette contents and their long-term health effects, he said. AP
