Mechanism of Action of Nicotine in the Central Nervous System Tobacco Dependence and Treatment Strategies Nicotinic Receptor Nicotine binds preferentially to nicotinic acetylcholinergic (nACh) receptors in the central nervous system; the primary is the α4β2 nicotinic receptor in the Ventral Tegmental Area (VTA) After nicotine binds to the α4β2 nicotinic receptor in the VTA, it results in a release of dopamine in the Nucleus Accumbens (nAcc) which is believed to be linked to reward Nicotine Stimulates Dopamine Nicotine May Cause Up-Regulation and Desensitization of Receptors Resulting in Nicotine activates α4β2 nicotinic receptors in the ventral Tolerance typically develops after long-term nicotine use1 tegmental area resulting in dopamine release at the Tolerance is related to both the up-regulation (increased number) nucleus accumbens. This may result in the short-term and the desensitization of nicotine receptors in the VTA1 reward/satisfaction associated with cigarette smoking.
A drop in nicotine level, in combination with the up-regulation and decreased sensitivity of the nicotinic receptor, can result in withdrawal symptoms and cravings1 Smokers have the ability to self regulate nicotine intake by the frequency of cigarette consumption and the intensity of inhalation1 In order to maintain a steady nicotine level, smokers generally titrate their smoking to achieve maximal stimulation and avoid symptoms of withdrawal and craving2 − α4β2 Nicotinic Receptor Adapted from Picciotto MR, et al.

The Cycle of Nicotine Addiction So Why Do People Smoke? Nicotine binding causes an increase in Addiction – Habitual psychological and physiological dependence release of Dopamine1,2 on substance or practice which is beyond voluntary control Dopamine gives feelings of pleasure – Stedman's Medical Dictionary The Dopamine decrease between Since at least the 1988 Surgeon General's Report1 cigarettes leads to withdrawal symptoms of irritability and stress1 – Addiction defined as compulsive use despite damage to the The smoker craves Nicotine to release individual or society and drug-seeking behavior can take more Dopamine to restore pleasure precedence over important priorities – Addiction persists despite a desire to quit or even repeated Competitive binding of Nicotine to nicotinic acetylcholinergic receptors causes prolonged activation, Most people smoke primarily because they are addicted desensitization, and upregulation2 As Nicotine levels decrease, receptors revert to an open state causing There is a clear link between smoking, nicotinic hyperexcitability leading to cravings1,2 receptors, and addiction2 1.

Multiple Quit Attempts Most Smokers Are Willing to More than 70% of US smokers have attempted to quit1 Of smokers who relapsed following a quit – Approximately 46% try to quit each year – Less than 5% who try to quit are abstinent 1 year later – 98% were willing to try again – Similar percentages in countries with established tobacco control programs (eg, Australia, Canada, UK)2 – 50% immediately • 30% to 50% try to quit; <5% achieve long-term abstinence – 28% within 1 month Some smokers succeed after making several attempts3 Of those willing to try again immediately – Past failure does not prevent future success – Percentage did not differ based on time since – Length of prior abstinence is related to quitting success Some smokers may prefer a waiting period before attempting to quit again 1.
