Tobacco smoke is incredibly harmful to health. Replacing cigarettes with cigar, pipe or hookah won't reduce health risks posed by smoking. According to American lung association, cigarettes contain about 600 ingredients, many of which are also in cigars and hookah. When they burn, they generate more than 7,000 chemicals many of which are toxic. At least 69 of them are carcinogenic, or known to cause cancer. The centers for disease control and prevention reports more than 4,80,000 deaths per year and note that smoking is most common preventable cause of death in the United States.
