A member asked:

How much nicotine is in a cigarette?

A doctor has provided 1 answer

About 9 mg: The nicotine in a cigarette is absorbed through smoke. The amount of nicotine that actually enters the body in this manner is usually less than 1mg. However, the nicotine is not the primary cause for concern in cigarettes. The bigger problem is that the smoke has hundreds of chemicals that attach to the lungs with the smoke's tar. This tar substance builds up, kills lung tissue, and causes cancer.
