Quizplus · Accepted Answer

Nicotine, as an agonist for the nicotinic receptors on skeletal muscle cells, will stimulate these cells to produce muscle contractions (twitches). This is why nicotine is often associated with increased motor activity and hyperactivity in individuals who smoke or use nicotine products. Muscle relaxation or paralysis would not be expected as a side-effect of nicotine use. Drowsiness is also not a common side-effect of nicotine use, although some individuals may experience fatigue or lethargy as a result of nicotine withdrawal.
