An electronic cigarette, or e-cigarette, is an electrical device that simulates the act of to***co smoking by producing an inhaled v***r bearing the physical sensation, appearance, and often the flavor (with or without ni****ne content) of inhaled to***co smoke, without its odor or, ostensibly, its health risks. The device uses heat (or in some cases, ultrasonics) to v***rize a propylene glycol- o
r glycerin-based liquid solution into an aerosol mist, similar to the way a nebulizer or humidifier v***rizes solutions for inhalation. The device's components usually include a small liquid reservoir, a heating element, and a power source, which may be a battery or a wired USB adapter. Most electronic ci******es are portable, self-contained cylindrical devices in varying sizes, and many are designed to outwardly resemble traditional ci******es. Liquids that produce v***r for electronic ci******es are available in many different flavor varieties and ni****ne concentrations, including ni****ne-free versions. The primary stated use of the electronic cigarette is an alternative to to***co smoking, or a smoking cessation device: It endeavors to deliver the experience of smoking without the adverse health effects usually associated with to***co smoke, or to at least greatly reduce those risks.
