Nicotine: A Stimulant Nicotine, the chemical that makes addicts out of cigarette smokers, is a stimulant with properties similar to those of cocaine and amphetamine (speed). Nicotine provides the pick-me-up that smokers feel.
This test quantitatively detects the presence of nicotine and two nicotine metabolites (cotinine and 3-hydroxycotinine), in serum. Nicotine acts as a central and peripheral nervous system stimulant. In addition, nicotine is highly addictive and is associated with short term adverse health effects, including elevated blood pressure, heart rate, and blood glucose levels.
