An electronic cigarette, or e-cigarette, is a device made of stainless steel or plastic that mimics a cigarette in terms of its appearance, use and sometimes tastes, but does not contain tobacco. A typical e-cigarette consists of a battery, an atomizer that heats the liquid and turns it into a vapour, and a cartridge that contains flavouring and (sometimes) nicotine in a base of propylene glycol (PG) or vegetable glycerin (VG) and water.
E-cigarettes are almost certainly less harmful than tobacco cigarettes, but little is known about their longer term safety.
The Ontario Tobacco Research Unit provides a short video on e-cigarettes and the most current science on the issue.
