This illustration is designed to educate patients about the role of dopamine in nicotine addiction. It explains how nicotinic receptors become desensitized with repeated exposure to nicotine and how this desensitization leads the receptors to upregulate.

This illustration is part of the iMD Health library of images. This illustration would be used by a doctor or pharmacist as a visual aid to explain the chemical basis of nicotine addiction to a patient beginning a smoking cessation treatment program.
