An electronic cigarette, e-cigarette or vapor cigarette, is a battery-powered device that provides inhaled doses of nicotine or non-nicotine vaporized solution. It is an alternative to smoked tobacco products, such as a cigarette. In addition to nicotine delivery, the vapor also provides a flavor and physical sensation similar to that of inhaled tobacco smoke, although there is no tobacco, combustion or smoke present. Most electronic cigarettes are designed to resemble cigarettes, cigars, or pipes, but some look more like ballpoint pens or screwdrivers. Most electronic cigarettes are reusable with replaceable and/or refillable parts, but disposable electronic cigarettes have also been developed. The electronic cigarette was invented by Chinese pharmacist Hon Lik in 2003 and introduced to the market the following year. The company he worked for, Golden Dragon Holdings, changed its name to Ruyan (meaning "to resemble smoking") and started exporting its products in 2005-2006.
