Effects of Secondhand Smoke

My father passed away from bladder cancer caused by secondhand smoke. Each year over 53,000 die from exposure to secondhand smoke. 3000 are diagnosed with lung cancer caused by secondhand smoke and 50,000 from heart disease. The carbon monoxide in smoke is deadly to someone prone to heart disease.
The components of the sidestream smoke coming off the tip of the cigarette are formed at a lower temperature, since oxygen is not being pulled through it, so more cancer causing substances are created at this lower temperature. The smoke is also not being filtered by either the cigarettes filter, nor the smokers body. Compare the color of the smoke coming out a smokers mouth and the color of the smoke coming off the tip of the cigarette--you can see the difference. White vs blue. The real problem is the side stream smoke which the smoker is exposed to and everyone around them. So even if you don't smoke, don't let anyone smoke around you. Encourage your city to go smoke free in public places to protect the rights of non-smokers to breathe clean, smoke free air.
