How does vaping affect health?

There are several health risks relating to vaping, notably to lung and heart health. Other risks include the presence of nicotine, other harmful chemicals, exposure to second-hand aerosol, and device malfunctions.

What are the health effects of vaping?

The e-liquid in vaping products, which is vapourized and then inhaled, contains a variety of chemicals. The long-term risks of inhaling these chemicals are still being studied but research is starting to show negative effects on both lung and heart health.

 As investigations into vaping products and related lung illnesses continue, QuitNow recommends that you consider refraining from using vaping products.

Risks to lung health

New research has found that vaping increases the risk of developing chronic lung diseases such as asthma, bronchitis, and emphysema. This risk is even higher for those who use both e-cigarettes and tobacco cigarettes.

There are also health risks linked to the chemicals found in vaping products. E-cigarettes contain some chemicals both suspected and known to causes cancer, as well as particulate matter than can penetrate deep into the lungs and cause cardiovascular damage.  The process of heating the e-liquid can produce additional chemicals whose health effects are still under investigation. There have been 14 cases of a severe vaping-related lung illness in Canada and over 2400 in the US, linked to exposure to certain chemicals in vaping e-liquids. 

  • In Canada, there has been one case of "popcorn lung disease", linked to a chemical called diacetyl found in some flavoured e-liquids. This disease is a form of chemical burn in the lungs.
  • Vitamin E acetate has been identified as a chemical of concern in the US outbreak of vaping-related illness
  • In the US, there was a case of cobalt lung disease, caused by inhaling an e-liquid that contained heavy metal particles which then settle into the lungs.
