E-cigarettes (also known as "electronic nicotine delivery systems" or "ENDS") were first available in North America in 2007, and are growing in popularity.

E-cigarettes have not been approved as cessation aids, and are unregulated in Canada. The sale of e-cigarette cartridges or 'juice' containing nicotine is prohibited in Canada.

The risks and benefits of e-cigarette are unknown due to a lack of long-term studies conducted by non-industry researchers. There is evidence of potentially hazardous chemicals and particles of metals in the liquid.
