Tobacco smoke contains over 7,000 chemicals. At least 172 of these are toxic and 69 are known to cause cancer.2 Tobacco is the only consumer product that will kill at least 1 in 2 regular users when used as it’s intended to be used.3

Non-smokers can get cancer from breathing in other people’s smoke. And people who chew tobacco increase their risk of getting cancer of the mouth (oral cancer), esophagus and pancreas,4,5 and chronic diseases like cardiovascular disease, chronic respiratory disease and diabetes.

Together, we could prevent about 2,780 cases of cancer in Alberta each year – if we support each other to be tobacco free.6

The toxic chemicals in tobacco can cause cancer, but the nicotine is what makes it addictive. It only takes seven seconds for nicotine to reach the brain. The nicotine causes euphoria, but soon larger doses are needed to produce the same effect. Tobacco users feel very strong symptoms when their nicotine levels drop.

Most people in Alberta who use tobacco want to quit.7 And there are many new support systems that make it easier than ever before.

Quitting is an important step toward preventing cancer and chronic diseases. It is the single best thing you can do to improve your health and protect the health of your friends and family. From the moment you quit, your health will begin to improve. The benefits just keep adding up, and even extend beyond cancer prevention.

  • Within 24 hours, your risk of heart attack decreases.
  • In 9 months, your lung function improves with less coughing and shortness of breath.
  • In 10 years, your risk of dying from lung cancer reduces by half.

If you smoke, quitting is the most important thing you can do to prevent cancer.
