  Electronic Cigarette

  The Electronic Cigarettewas developed in China in 2004. It was designed to take the place of smoking tobacco cigarettes and cigars because, despite global smoking bans, many smokers just find it too difficult to quit altogether. There are numerous nicotine replacement products on the market, such as gum and patches, but these in no way replicate the smoking experience which has been proven to be a part of the addictive ritual of smoking. The e-cigarette is revolutionary in that its aim is to both deliver nicotine to user and simulate the experience of smoking a traditional tobacco cigarette.

  The Electronic Cigarette or e-cig, in most cases looks just like a traditional cigarette and is made of a mouthpiece that holds a nicotine cartridge, a heating element or atomizer, a battery and an LED at the tip of the device. The way e-cigs work is that they contain an airflow meter that is triggered when the user inhales on the device. This activates the atomizer and delivers the nicotine to the smoker by a short burst of vapor that is inhaled. The LED at the tip lights up showing that the battery is working and also making the device appear similar to a lit cigarette. The vapor that is exhaled may look like smoke but it is actually just water, propylene glycol based vapor that is odorless and harmless.

  E-cigarettes come in many shapes, colors and flavors. There are the models that look like traditional cigarettes and also some that are made to look like fountain pens. Flavors are limitless from Marlboro and Camel to Mint and Chocolate, with new flavors being developed constantly. The cartridges are also available with different levels of nicotine. The various levels of nicotine allow the smoker to naturally wean themselves off of nicotine slowly.
