E-cigarettes come in different forms with most having a battery, a heating element and a place to hold liquid. The liquid contains glycerin and propylene glycol to aerosolize the contents and usually contains nicotine as well as artificial flavoring. When heated, other chemicals may be released. Through heating, the liquid is vaporized and then inhaled. As such, use of an e-cigarette is commonly referred to as vaping. Recent data indicates that 23% of Canadian high school students and 15% of the general population in Canada have tried an e-cigarette.

The US Centre for Disease Control states that nicotine-based e-cigarettes may help cigarette users to quit tobacco smoking but also point out that this doesn’t mean that e-cigarettes are safe. In fact, the US CDC states, “E-cigarettes are not safe for youth, young adults, pregnant women, or adults who do not currently use tobacco products.” The Public Health Agency of Canada (PHAC) states that vaping can increase exposure to harmful chemicals and can lead to nicotine addiction while Health Canada supports e-cigarettes as a harm reduction tool. The vaping industry (dominated by ‘big tobacco’, with a history of denying evidence regarding harms of its product) promotes vaping as conferring a net benefit in spite of the risks.

In this context, major issues remain, including: a) what is the state-of-art in terms of toxicity of these products and what are the unknowns that need be resolved to inform our decision-making; b) should e-cigarettes be available, unrestricted, as a harm reduction tool for existing tobacco users, or should they only be made available through government-regulated health care providers; c) what should be the role of the tobacco and vaping industry in this setting? Our expert panel will discuss this issue of critical public health importance.
