Smoking and tobacco

The single best thing you can do to improve your health is to quit smoking. We can help. 

Smokers’ Helpline is a free, confidential service that can help you develop a quit program, provide tips to deal with cravings and withdrawal symptoms and refer you to support services in your community.

  • Quit now and reduce your risk of cancer

    It’s estimated that smoking is responsible for 30% of all cancer deaths in Canada and is related to more than 85% of lung cancer cases.

    The more you smoke and the longer you smoke, the more you increase your risk of developing lung cancer. In fact, any smoking at all may cause lung damage over time.

    Quitting isn't easy but it's worth it. Within 10 years of quitting, an ex-smoker’s overall risk of dying from lung cancer is cut in half. And your risk of these cancers goes down – mouth, throat, larynx, esophagus, bladder, kidney, pancreas and cervix.

  • Quit and feel better in so many ways

    As soon as you stop smoking, your body begins to cleanse itself of tobacco poisons. Here’s how:

    • Within 20 minutes, your blood pressure and pulse rate return to normal.
    • Within 8 hours, carbon monoxide levels in your blood drop.
    • Within 2 weeks to 3 months, you’ll find it easier to breathe because your lungs are working better.
    • After 1 year, your risk of a smoking-related heart attack is reduced by half.
    • After 10 years, your risk of dying from lung cancer is about half that of someone who is still smoking.
  • Get help to quit – One Step at a Time

    One Step at a Time is our series of booklets on smoking and quitting. They will help you understand why people smoke and guide you through the process – once you’re ready to quit. These free guides have been reviewed by independent experts and are based on the best available science about quitting smoking.
