The US Food and Drug Administration said that it plans to regulate smokeless electronic cigarettes as tobacco products and won't try to regulate them under stricter rules for drug-delivery devices.
The federal agency said that it intends to propose rule changes to treat e-cigarettes the same as traditional cigarettes and other tobacco products.
The news is considered a victory for makers and distributors of the devices, which continue to gain popularity worldwide.
E-cigarettes are plastic and metal devices that heat a liquid nicotine solution in a disposable cartridge, creating vapour that the "smoker" inhales. A tiny light on the tip even glows like a real cigarette.
Users and distributors say e-cigarettes address both the nicotine addiction and the behavioural aspects of smoking –the holding of the cigarette, the puffing, seeing the smoke come out and the hand motion –without the more than 4,000 chemicals found in cigarettes.
First marketed overseas in 2002, e-cigarettes didn't become easily available in the US until late 2006. Now, the industry has grown from the thousands of users in 2006 to several million worldwide, with tens of thousands new e-smokers every week.
No timeline set
The FDA said e-cigarettes could still be regulated as drugs or drug-delivery devices if they are "marketed for therapeutic purposes" –for example, as a stop-smoking aid.
Craig Weiss, president of Sottera Inc., the Arizona-based company involved in the lawsuit that led to the FDA's decision, said he was "very happy" with the agency's decision. The company markets NJOY brand e-cigarettes.
Jason Healy, president of e-cigarette maker Blu Cigs, also praised the decision. Once the FDA's rules covering e-cigarettes are in place, he said, they will help in "weeding out the shady companies."
Right now, "you can potentially sell snake oil," Healy said.
Some e-cigarette makers have claimed the products will help smokers quit using traditional cigarettes, while other manufacturers have tried to steer clear of the issue.
Nearly 46 million Americans smoke cigarettes. About 40% try to quit each year, according to the Centres for Disease Control and Prevention. But unlike nicotine patches or gums, e-smokes have operated in a legal gray area.
The FDA has said its tests found that the liquid in some electronic cigarettes contained toxins besides nicotine –which is toxic in large doses as well as carcinogens that occur naturally in tobacco.
But some public health experts say the level of those carcinogens was comparable to those found in nicotine replacement therapy, because the nicotine in all of the products is extracted from tobacco.
