Nicotine in cigarette smoke is absorbed from the lungs, whereas nicotine in cigar smoke and smokeless tobacco is absorbed from the bloodstream. When a person inhales cigarette smoke, the nicotine in the smoke is absorbed through the alveoli in the lungs and enters the bloodstream, which carries it to various organs and tissues in the body. On the other hand, in the case of cigar smoke and smokeless tobacco, the nicotine is absorbed directly through the mouth or nasal cavity and enters the bloodstream from there.
