Theres already so much pollution, what difference does tobacco smoke make?
Auto emissions and factory discharges are controlled. Secondhand smoke contains at least 250 chemicals known to be toxic, including more than 50 that can cause cancer. Tobacco smoke paralyzes the cilia in people’s respiratory systems — and reduces the capability of our bodies to handle other pollutants, which are a part of our lives. Also, pollutants are synergistic; several together can be more harmful than the sum of their individual effects. Many of the pollutants in tobacco wouldn’t be allowed if the source were something other than smoking.
