Electronic cigarettes

Description

An electronic cigarette is a device which, when activated, heats a liquid and transforms it into an aerosol that is then inhaled. When the aerosol is inhaled, it is also called vaping. Unlike conventional cigarettes, electronic cigarettes do not contain tobacco and are not burned.

According to the Québec Survey on Tobacco and Vaping Products, in 2023, 7% of Quebecers aged 15 and over said they had smoked in the 30 days preceding the survey. In 2020, the figure was 4%.

Ingredients

Most liquids used in electronic cigarettes contain:

  • solvents or bases (propylene glycol and vegetable glycerin)
  • artificial flavours or aromas
  • nicotine

The liquids or the aerosol may also contain other chemicals.

Common names

Electronic cigarettes are also known by the following names:

  • mods
  • pods
  • vaporizer
  • low-resistance electric vaper (sub-ohm)
  • tank system
  • electronic nicotine delivery system
  • vape

Health risks

Risks associated with nicotine

Most vaping liquids contain nicotine. People can quickly develop a strong dependence on this substance, especially young people. Dependence can develop even if the person only uses electronic cigarettes with nicotine occasionally.

When used by young people, nicotine can have harmful effects, especially on the developing brain. Nicotine can affect memory and concentration and lower impulse control.

Risks associated with vaping products with or without nicotine

Vaping may be associated with adverse health effects. If you vape, monitor yourself for symptoms of pulmonary illness, such as cough, shortness of breath or chest pain. If you develop these symptoms, see a doctor immediately. For more information about the risk of pulmonary illness, consult Maladies pulmonaires associées au vapotage (vaping-related pulmonary illness) page from the Ministère de la Santé et des Services sociaux website.

Little is known about the other long-term effects of vaping on health. The ingredients in vaping liquids, such as propylene glycol and vegetable glycerin, are generally safe to eat, but not necessarily safe to inhale.

As for the aerosol produced during vaping, it contains chemical components different from those found in tobacco smoke. These chemical components also carry health risks.

The many types of devices and ingredients and their rapid development make conducting studies on the health risks of electronic cigarettes challenging.

Help and resources to stop vaping

If you want to stop vaping products with nicotine, free services are available to help you:

Electronic cigarette use among adolescents and young adults

In Québec, the sale and purchase of electronic cigarettes are prohibited for anyone under 18 years of age. However, their use among adolescents has been growing in the past few years. According to the 2016-2017 Québec Health Survey of High School Students (QHSHSS), 11% of high school students in Québec reported using electronic cigarettes in the last 30 days. According to the same survey conducted in 2022-2023, this figure had increased to 16%.

Stop smoking aid

Many people think that electronic cigarettes are an effective stop smoking aid. According to the World Health Organization, there is insufficient data to support this. Some studies show that using electronic cigarettes could help some smokers stop smoking. Others show that their use could make it harder to quit smoking. The dual use of electronic cigarettes and combustible products, such as cigarettes or cigars, is not recommended, for it could increase the health risks.

For a product to be officially recognized as a smoking cessation aid, it must be approved by Health Canada. To date, no manufacturer of vaping products has obtained Health Canada approval.

Regulation

In Québec

Québec adopted the Tobacco Control Act in November 2015. Under this Act, electronic cigarettes with or without nicotine are subject to the same provisions as tobacco products with respect to their sale, promotion, advertising and where they can be used. The regulation prohibits:

  • the sale of electronic cigarettes to anyone under 18 years of age
  • the online sale of electronic cigarettes
  • electronic cigarette advertising (except advertising in newspapers or magazines that have an adult readership of not less than 85%)
  • the display of electronic cigarettes in retail outlets accessible to people under 18 years of age
  • access to specialty vape shops for anyone under 18 years of age
  • the sale of electronic cigarettes with a flavor or aroma other than that of tobacco (the sale of a product without flavor or aroma remains permitted
  • the use of electronic cigarettes in places where smoking is prohibited

Anyone who does not comply with the regulations on electronic cigarettes may be subject to a fine. For more information, to make a complaint or to report a case of non-compliance, please contact the Inspecteur national des services du domaine de la santé et des services sociaux. You will find the contact information in the section Information requests and complaints regarding the application of certain laws and regulations (in French only).

In Canada

Electronic cigarettes are regulated by the federal government under the Tobacco and Vaping Products Act. For instance, this regulation, which came into force in May 2018:

  • prohibits the use of certain ingredients in their manufacture
  • prohibits the promotion of flavours that appeal to young people
  • sets out rules for product and packaging labelling
  • establishes restrictions on advertising and promotion
