What is Vaping?

Vaping products (also know as e-cigarettes, vapes, juuls, mods, etc.) are electronic nicotine delivery devices that heat a liquid solution to produce a vapour. The aerosol is inhaled through a mouthpiece and is then absorbed into the bloodstream. 

Vaping products are available in many different forms. Some are designed to look like cigarettes, some are the size of a USB or pen, and others are much larger and may be modifiable. Most e-cigarettes contain nicotine, a highly addictive substance. Click here to learn more about nicotine addiction. 

Most e-cigarettes 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 and also have their own distinct risks. From what is known so far, vaping can damage the respiratory, cardiovascular, and immune systems and lead to increased risk of chronic pulmonary disorders, stroke, and heart attack. Some people have also experienced acute (immediate) lung injuries from vaping.

Risks to Respiratory System

Vaping irritates the throat and can lead to coughing, wheezing, and other respiratory symptoms. Over time, it inflames your airway and increases your risk of developing chronic lung diseases such as asthma, bronchitis, Chronic Obstructive Pulmonary Disorder (COPD), and emphysema. This risk is even higher for those who use both e-cigarettes and tobacco cigarettes. 

Some of the chemicals and by-products in vaping devices can build up in your lungs and cause long-term damage. The process of heating the e-liquid can produce additional chemicals that might be toxic when inhaled. These chemicals and their health effects are still under investigation.


Risks to Cardiovascular System

Vaping raises your blood pressure and can increase your risk of heart disease. Using a vaping product just once was shown to increase people's heart rates and cause their arteries to stiffen.  Over time, vaping may cause damage to the lining of the arteries responsible for regulating inflammation and blood clotting.  

Vaping increases your risk of having a stroke, especially at a younger age. 

Vaping may also increase your blood sugar levels and lead to prediabetes, putting you at risk for type 2 diabetes. 


General Health Risks

Vaping may also contribute to poor oral health and increase your risk of gum disease.

 Vaping can also contribute to vision loss. 

Vaping may weaken bones and increase risk of fractures and bone breaks. 



Health risks of nicotine

Nicotine is approved for use in nicotine replacement therapies, such as the nicotine patch or gum. However, there are risks linked to nicotine and it is a highly addictive substance. As well, exposure to nicotine from tobacco is known to contribute to increased heart rate and blood pressure and to cardiovascular disease, and it is suspected that nicotine exposure from vaping has similar long-term cardiovascular effects. 

Vaping products contain nicotine in various concentrations, compared to more standardized amounts found in cigarettes and nicotine replacement therapy. Some products contain much higher levels of nicotine than cigarettes. Vaping with nicotine can also lead to side effects like seizures or blackouts, due to inhaling too much nicotine in a short period of time. This is considered a form of nicotine poisoning. 


Risks of nicotine for children and youth

 Young people are especially vulnerable to the effects of nicotine. The human brain is still developing in adolescence and continues to develop past age 25.  Using nicotine in adolescence disrupts cognitive function and can permanently alter the parts of the brain that control attention, learning, and memory. 

Nicotine use in adolescence also impacts: 

  • Mood: increased risk of depression and/or anxiety; increased irritability 

  • Behaviour: reduced impulse control, difficulty concentrating 

Young people can get addicted to nicotine more easily than adults. Nicotine use in adolescence may also increase the risk of future addiction to other drugs. 


Risks of nicotine for pregnant women

Nicotine can be harmful to fetal development and can lead to adverse effects in brain or lung development and to low birth weight.


Second-hand vapour

Bystanders can also be exposed to aerosol (vapour) that is exhaled by people vaping. This aerosol contains heavy metals and ultrafine particles that those nearby can inhale. So far, little is currently known about the possible health effects of secondhand exposure to e-cigarette aerosol. It may contribute to an increased risk of bronchitis symptoms (e.g., daily coughing or wheezing) and shortness breath, especially among young adults.  Those who vape should be cautious not to vape around others, especially those who do not smoke or vape themselves.


Device malfunctions

There have been injuries due to vaping product malfunctions, including explosions and fires. For more information on product safety requirements, and how to protect yourself, read about vaping product, safety and regulation.

Dual Smoking and Vaping

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 use only cigarettes or only e-cigarettes.
