Second-hand smoke contains more than 4,000 chemicals and close to 70 of those chemicals are known or suspected to cause cancer.

No level of second-hand smoke is safe. Second-hand smoke exposure is related to sudden infant death syndrome and respiratory heath problems.

The risk of asthma and ear infection in children is greater when they are exposed to second-hand smoke.

The Canadian Cancer Society applauds Ontario’s new smoke-free vehicle legislation, as it is a measure that will protect children from the harmful effects of second-hand smoke.

The legislation, which came into effect Jan. 21, prohibits smoking in vehicles when a person who is younger than 16 years of age is present in the vehicle.

While we support this new law, the Society believes the best way to protect children’s health is to help parents and caregivers quit smoking. We can help.
