The Electronic Cigarette
An electronic cigarette, e-cigarette or e-cig, is an electrical device that simulates the act of tobacco smoking by producing an inhaled mist bearing the physical sensation, appearance, and often the flavor and nicotine content of inhaled tobacco smoke; though lacking its odor, and intended to omit its health risks. The device uses heat to vaporize a propylene glycol- or glycerin-based liquid solution into an aerosol mist, similar to the way a nebulizer or humidifier vaporizes solutions for inhalation.
Most electronic cigarettes are portable, self-contained cylindrical devices the size of a ballpoint pen or magic marker; though sizes vary, mainly due to differing battery capacities. Many electronic cigarettes are designed to resemble actual cigarettes or cigars, or even pipes. Most are also reusable, with replaceable and refillable parts, but some models are disposable.
The primary stated use of the electronic cigarette is an alternative to tobacco smoking, as it attempts to deliver the experience of smoking without, or with greatly reduced, adverse health effects usually associated with tobacco smoke. Nevertheless, concerns have been raised that use of the device still carries health risks, and that it could appeal to non-smokers, especially children, due to its novelty, flavorings, and possibly overstated claims of safety.
Origins of the Electronic Cigarette
The electronic cigarette concept first appeared in a patent acquired by Herbert A. Gilbert in 1963. The device was described as, "...a smokeless non-tobacco cigarette ... to provide a safe and harmless means for and method of smoking by replacing burning tobacco and paper with heated, moist, flavored air..." Due to the limitations of technology available at the time, and because tobacco was not yet generally accepted as harmful, this device never reached manufacturing.
The modern 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, before receiving the first international patent in 2007.
Liquid solutions containing nicotine are available in differing nicotine concentrations to suit user preference. Dosing nomenclatures are not standardized and vary by manufacturer, but tend towards the following rough figures:
- Liquids said to contain "low" doses of nicotine tend to correspond to a nicotine concentration of 6–8 mg/ml (milligrams of nicotine per Milliliter of liquid).
- "Midrange" or "medium" doses tend to correspond to a nicotine concentration of 10–14 mg/ml.
- "High" doses tend to correspond to a nicotine concentration of 16–18 mg/ml.
- "Extra-high" doses tend to correspond to a nicotine concentration of 24–36 mg/ml.
Actual numerical nicotine concentration ratings are usually printed on liquid containers or cartridge packaging. Often, the standard notation "mg/ml" is shortened to a simple "mg".
Flavors and nicotine are dissolved in hygroscopic components, which turn the water in the solution into a smoke-like vapor when heated. Commonly used hygroscopic components include propylene glycol, vegetable glycerin, (often sold under the abbreviations PG and VG).Safety of liquid bases
Both liquid bases are common food additives used in a variety of pharmaceutical formulations. Propylene glycol, the current dominating liquid base, has been utilized in asthma inhalers and nebulizers since the 1950s, and because of its water-retaining properties, is the compound of choice for delivering atomized medication. The U.S. Food and Drug Administration (FDA) includes propylene glycol on its list of substances Generally Recognized as Safe (GRAS), and it meets the requirements of acceptable compounds within Title 21 of the Code of Federal Regulations.
