Smoking is linked to more than two dozen diseases and conditions, including cancer and heart disease. Most of these start to reverse after you quit smoking. Sometimes the benefits of quitting begin in a matter of hours.


Health risks for people who smoke

All people who smoke are at increased risk for:

  • problems with their heart and blood vessels
  • certain types of cancers
  • lung and respiratory problems
  • other health issues
  • premature death

Female smokers are also at increased risk for:

  • cancer of the cervix
  • problems with periods (menstrual problems)
  • problems getting pregnant (fertility problems)
  • premature delivery
  • having a low birth weight baby

Male smokers are also at increased risk for:

  • problems with erections (impotence/erectile dysfunction)

Each day, 100 Canadians die of a smoking-related illness.

The good news? Life expectancy improves after you quit.


Risks from other types of tobacco

Cigar and pipe smokers experience the same types of health problems as cigarette smokers.

Smokeless tobacco (including chewing tobacco and snuff) also contains many of the same harmful and addictive substances as cigarettes, pipes, and cigars. Smokeless tobacco is a major cause of cancer of the mouth and throat. It can also cause serious dental health problems, including receding gums, tooth loss, and discoloured teeth and gums.
