Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: \- Many cigarette smokers claim that smoking helps them stay alert and improves their concentration, and have reported problems in attention and concentration after quitting smoking. Some research has indicated that nicotine can enhance certain aspects of attention and memory in humans. However, more research is needed to determine how nicotine affects different elements of the brain's ability to pay attention. Knowing which aspects of attention are affected by nicotine may help produce new medications and therapies to help people successfully stop smoking. Objectives: * To investigate the dose-related effects of nicotine on the ability to pay attention in smokers and nonsmokers. * To compare the effects of nicotine in smokers and nonsmokers. Eligibility: \- Individuals between 18 and 50 years of age who are either current smokers (at least 15 cigarettes per day on average for at least 2 years) or healthy, nonsmoking volunteers. Design: * The study will consist of one training session and three testing sessions. Each session will last about 2 hours. * The training session will introduce participants to the study tests and evaluate their tolerance of the two levels of nicotine nasal spray used in the study. Smokers will receive the higher dose of nicotine to introduce them to the effects of the spray. Nonsmokers will be given first the lower dose of the spray, followed by higher dose at least 30 minutes later. Nonsmoking participants who cannot tolerate the higher dose will not continue in the study. * At the start of each testing session, smokers will have one cigarette to standardize the time of the most recent exposure to nicotine. * During the testing sessions, participants will receive a placebo spray, a lower dose of nicotine, or a higher dose of nicotine, and then will be asked to perform tests that evaluate mood, attention, and performance.
