What’s in a vape?
Most vapes (also called e-cigarettes) contain nicotine, and many also contain a wide range of flavourings and chemicals. Chemicals in vaping e-liquids can also react when heated and form new chemicals. There is still a lot we don’t know about how these chemicals could impact your health.
What are the health risks of vaping?
Vaping products share many of the same risks as tobacco products but also have their own distinct risks. From what is known so far, vaping can damage the respiratory, cardiovascular, and immune systems. Some people have also experienced acute (immediate) lung injuries from vaping.

Dual Use: Smoking and Vaping
It’s common for people to use both cigarettes and vapes—this is called dual use. Using both cigarettes and vaping products at the same time can increase the negative health consequences compared to using either product alone. Research has found that vaping increases the risk of developing chronic pulmonary diseases including asthma and emphysema by 30%, and dual use triples this risk. Dual use also increases your risk of stroke compared to using only cigarettes or only e-cigarettes.
If you decide to try vaping to quit smoking (see FAQ below), ensure you switch completely to vaping in order to reduce your health risks.
