Tobacco-Free Living - Protection From Second-Hand Smoke

Second-hand smoke or Environmental Tobacco Smoke (ETS) is the smoke a smoker blows into the air and the smoke from the burning end of a tobacco product (i.e. cigarette, cigar, pipe).

Why is it dangerous?

  • There are more than 4,000 chemicals in second-hand smoke; more than 50 of these can cause cancer.
  • Smoke from the burning end of a cigarette has more harmful chemicals in it than smoke inhaled directly by a smoker through a filtered cigarette.
  • Ventilation systems do not remove all of the harmful chemicals found in second-hand smoke.
  • There is no safe level of exposure to second-hand smoke.

    How does second-hand smoke harm your health?

    • Second-hand smoke causes between 1,100 and 7,800 deaths per year in Canada, one third of these are in Ontario.
