Clearing the air on e-cigarettes
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.
