Nicotine affects cognition and behavior (1). In smokers and nonsmokers, it produces small improvements in finger-tapping rate, motor response on tests of focused and sustained attention, and recognition memory (2). In smokers, tobacco deprivation can impair cognitive performance, and subsequent nicotine administration or smoking can reverse these deficits (3–5).
