Clearing the air on e-cigarettes

Do e-cigarettes deserve their bad reputation or are they a viable smoking cessation aid?

Electronic cigarettes are battery-powered devices that create a vapour for inhalation.


In most instances this vapour contains nicotine dissolved in propylene glycol or glycerine.1

The vapour may also contain flavourings. E-cigarettes have either a disposable or refillable tank containing the fluid that is heated by the device to create a fine vapour.

Unlike cigarette smoke, the vapour does not contain monoxide or other toxic products of combustion.
