Britain will start regulating electronic cigarettes and other products containing nicotine as medicines, AP quoted the country's top regulator as saying. E-cigarettes are battery-operated products that turn nicotine into a vapor inhaled by the user. The Medicines and Healthcare Products Regulatory Agency said in a statement Wednesday it would treat e-cigarettes as medicines, "so that people using these products have the confidence they are safe, are of the right quality and work." E-cigarettes and other nicotine products will be licensed in the U.K. from 2016, giving manufacturers time to ensure their products comply with all standards for medicines. The U.K. regulator says e-cigarettes aren't recommended for use until then, but it won't ban them entirely. "While it's best to quit completely, I realize that not every smoker can and it is much better to get nicotine from safer sources such as nicotine replacement therapy," Britain's chief medical officer, Sally Davies, said in a statement. "It's only right (e-cigarettes) are properly regulated to be safe and work effectively." Cigarettes are exempt from the regulation. Smoking is the biggest cause of preventable deaths in England, killing about 80,000 people every year. Once e-cigarettes and other nicotine products are licensed by the U.K. regulator, they will be available for sale as over-the-counter medicines. Britain said it will now push for European law to recognize nicotine products as medicines.
