Like a lot of people, you may think that other people’s tobacco smoke is simply a bit unpleasant. But it is much worse than that. Secondhand smoke is harmful to health.
Second hand (or passive) smoking is the smoke that you breathe in from other people’s cigarettes. This is the smoke exhaled by you, plus the smoke created by the lit end of a cigarette. Most of the secondhand smoke is invisible and odorless, although you may not notice everybody’s health can be affected. Children are particularly vulnerable, their chances of getting asthma doubles. And if they already have asthma, breathing will worsen. Pregnant women exposed to secondhand smoke can pass on the harmful chemicals to their baby.
