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 U.S. and elsewhere — and the scrutiny of world health officials.
Marketed as a healthier alternative to smoking and a way to kick the habit, the smokeless smokes have been distributed in swag bags at the British film awards and hawked at an international trade show. Advertisement 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. 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.
