Final answer:
A partial agonist of nicotinic acetylcholine receptors can help with smoking cessation by reducing cravings and attenuating the rewarding effects of nicotine.
Step-by-step explanation:
A partial agonist of nicotinic acetylcholine receptors can be helpful with smoking cessation by reducing withdrawal cravings and attenuating the rewarding effects of nicotine. Nicotine, the active chemical constituent in tobacco, stimulates nicotinic acetylcholine receptors and is addictive. By using a partial agonist, it can bind to these receptors and produce a weaker effect compared to nicotine, helping to reduce cravings and withdrawal symptoms.
