E-cigarettes will be regulated as tobacco products, federal authorities announced on Thursday. In a long-awaited ruling, the U.S. Food and Drug Administration (FDA) finalized rules that give the agency authority to regulate all tobacco products including e-cigarettes, cigars, hookah tobacco and pipe tobacco, as well as other products. Until now, e-cigarettes were not regulated by the FDA and there was no national law to prohibit the sale of e-cigarettes, hookah tobacco or cigars to people under 18. “The actions being taken today will help the FDA prevent misleading claims by tobacco product manufacturers, evaluate the ingredients of tobacco products and how they are made, as well as communicate their potential risks,” the agency said in a statement. The new rule means the agency will have to approve all products that made it to market as of Feb.
