Electronic cigarettes (e-cigarettes) are battery powered devices that mimic the effects of traditional cigarettes. E-cigarettes are usually comprised of three main parts:
- battery
- cartridge
- contains water, flavouring and nicotine in a base of propylene glycol and glycerine solution
- atomizer/ vaporizer
By taking a puff of the device, the atomizer is activated and heats the cartridge solution. As a result, vapour is produced which can then be inhaled. This is the action referred to as “vaping.” Sometimes, an indicator light is included on the end of the tool in attempt to mimic a tobacco cigarette.
Who Uses E-Cigarettes?
Since the introduction of e-cigarettes, the use has increased by substantial amounts, especially in the younger population. It is estimated that over 4 million Canadians have tried using an e-cigarette. The reason usage is so large may be due to:
- the perception that e-cigarettes are less harmful than traditional cigarettes
- they are thought to be a desirable method to quit smoking
- they are convenient
- they are often permitted in location where smoking would otherwise be prohibited
- simply out of curiosity
