Did you know?
Studies show that each cigarette shortens your life by about 10 minutes.
- Of every 1,000 Canadians aged 20 who continue to smoke, about half (500) will die from smoking - 250 of them before the age of 70.
- On average, people who die from smoking lose 15 years of their expected life!
Are pipes and cigars safe?
Smoke from pipes and cigars can harm you too. Many people who smoke pipes and cigars do not inhale - but they have more risk of getting cancer of the lip, mouth, tongue or throat. And most people who switch from cigarettes to pipes do inhale!
Smokeless Tobacco is also very harmful!
Some people believe that by "chewing" tobacco rather than smoking they are avoiding the health risks involved. It leads to nicotine addiction, causes cancer of the mouth, esophagus (the passage that connects the throat to the stomach), and pancreas (a gland that helps with digestion and maintaining proper blood sugar levels) and increases the risk for death from heart disease and stroke.
