Question

Quizplus · Accepted Answer

The major way that nicotine is metabolized and eliminated from the body is through the liver, and then excreted through the kidneys in the urine. Some small amounts may also be excreted through saliva, feces, and breath. There is limited evidence suggesting that a small amount of nicotine may be excreted through sweat, but it is not considered a major route of elimination.
