Cigarette smoking is the leading cause of morbidity and mortality worldwide, contributing to an estimated more than 6 million deaths annually.1 Combining pharmacotherapy with behavioral interventions is the most effective way to help smokers sustain abstinence.1-3 Pharmacological therapies help smokers adapt to the absence of nicotine after quitting smoking by reducing nicotine withdrawal symptoms. In the general population of smokers, varenicline or a combination of prolonged- and short-acting nicotine replacement therapy (NRT) are the first-line agents for smoking cessation therapy.1-3
