AA and EA smokers undergo detailed monitoring of smoking behavior, receive known doses of nicotine to establish nicotine metabolic rate, undergo DNA testing, and have their responses to not smoking for several hours studied. Exposure to carcinogens and other tobacco smoke toxins is also measured.  It is hypothesized that there are racial differences in metabolism that may explain different patterns of smoking, and that this in turn influences the reasons why smokers continue to self-administer nicotine (i.e., continue to smoke).
