An electronic cigarette (or e-cigarette, e-cig) is a cigarette substitute. It gives small amounts of the chemical nicotine without the tobacco or other chemicals from real cigarettes. The main substances making up in the liquid in the e-cigarettes are nicotine, propylene glycol, glycerin and some flavors or smells.
Chemistry
The propylene glycol and the glycerin react and make a vapour which looks like the smoke from real cigarettes. Some people may be allergic to the chemicals in the Electronic Cigarette.
History
The original inventor of the electronic cigarette concept was Ruyan and his first patent was registered in 2003. One year later, Ruyan’s first international patent was also registered. The name "Ruyan" translates to "smoke anywhere". Soon, factories in China started making similar devices based on Ruyan's ideas. Many of these creations were soon sponsored by different companies and not only marketed as smoking alternatives but also as an NRT (nicotine replacement therapy).
In 2008, this attracted the attention of the World Health Organization (WHO) who said that these e-cigarettes were not proper nicotine replacement therapy and that this mis-information had to be taken away from any sites or advertisements saying that they were.[1]
