E-cigarettes, or e-cigs, are electronic devices that vaporize liquid, which is then inhaled by the user. Some e-cigs allow the user to control the amount of nicotine in the vapor. E-cigs are not subject to laws restricting tobacco smoking in public places and buildings. While e-cigs may help smokers quit tobacco, their availability to all ages could increase youth smoking. The long-term health effects of e-cigs are still unknown due to their recent introduction.
