The carbon monoxide from passive smoke can be deadly for young children. Within the first year of life, children of parents who smoke are more frequently hospitalized for bronchitis and pneumonia. Infants are more susceptable to second hand smoke and many develop cancers when they are older. Alergies, asthma and heart problems are also seen in children who have parents who smoke. Even minor reprecutions such as cough and/or phlegm or repeated ear infections are evident as well. Parents are even being considered of inflicting child abuse if smoking takes place in the home.
