What we know so far

This section is about vaping nicotine or e-juice using e-cigarettes or vapes. It doesn’t cover vaping cannabis.

Vaping can feel like a safer choice than smoking, but it’s not risk-free. Research is still catching up, especially for youth and long-term use. Knowing the facts can help you make choices to protect your health.

Key points about vaping

  • Vapes heat a liquid – usually with nicotine – into a mist you breathe in.

  • They have significantly fewer toxins than cigarettes, but they are not harmless and we don’t know the long-term effects.

  • Vaping can raise blood pressure, irritate lungs and cause strong nicotine addiction.

  • Flavourings change when heated, and some flavours are more harmful than others.

What we know

1. Types of devices

  • Disposables: Use until liquid is done, then throw away.
  • Pods: Small vapes with snap-in cartridges.

3. Can vaping help you quit smoking?

  • If other quit methods – like coaching, counselling or quit aids like NRT, medications or cytisine – haven’t worked for you, talk with a quit coach or health care provider. Switching fully to vaping could increase your chances of staying smoke-free.
  • It’s important to talk to a health care provider before switching if you:
    • Are pregnant or breastfeeding/chestfeeding.
    • Have heart or blood pressure issues.
    • Use other substances like cannabis or alcohol.
