The use of e-cigarettes, which are electrical devices that heat flavored nicotine liquid into a vapor that is inhaled, much like traditional cigarettes but without the smoke, has been rising rapidly among youths in recent years, raising concerns about the potential for addiction risks and health damage.
E-cigarettes are currently unregulated, meaning they can be sold to youths and are openly advertised, unlike cigarette-makers which must follow strict rules about where and how their products are marketed.
