how many nicotine in a cigarette
The Facts. The average cigarette in the United States contains about 9mg of nicotine. However, this is not the amount of nicotine that is ingested by the smoker. Cigarettes are burned and the smoke is inhaled by the person, so the nicotine is absorbed through the smoke. The amount of nicotine that actually enters the body in this manner is typically less than 1mg.
