Second-hand Smoke

Are you a non-smoker? Are you shy about defending yourself against smokers? Or are you a smoker who doesn't realize the harm you may be doing to non-smokers?

Non-smokers are no longer a silent majority. They mind if you smoke. And they're speaking up. They know tobacco smoke pollutes their air. And new research gives them facts to defend themselves. It shows that second-hand smoke (also referred to as environmental tobacco smoke and sidestream smoke) has harmful effects on non-smokers.

  • Contains more hazardous substances than inhaled smoke and contains 2.7 times as much nicotine, 70% times more tar and 2.5 times greater carbon monoxide levels.

  • Two-thirds of the smoke from the burning cigarette goes into the air.

  • Sidestream smoke has higher amounts of cancer-causing and other dangerous things than the mainstream smoke inhaled by the smoker.

  • There is twice as much tar and nicotine in sidestream smoke than mainstream.
