How is second-hand smoke worse than first-hand smoke?
It not only hurts you but every innocent person around you who doesn’t want to smoke. Every one who breathes in second-hand smoke is endangering their health, but young children are particularly at risk as their lungs are smaller and more delicate. They are, therefore, seriously affected by tobacco smoke and the chemicals it contains. Young people exposed to second-hand smoke at home are seven times more likely to smoke. Second-hand smoke contains cancer-causing and other toxic substances that are often in greater concentrations than in the smoke inhaled by the smoker. Some chemical compounds found in smoke only become carcinogenic after they’ve come into contact with certain enzymes found in many of the tissues of the human body, so the smoke that is breathed out may be worse than the smoke breathed in by the smoker through the cigarette.
