Brain metabolic changes during cigarette craving.
TLDR
Brain regions associated with arousal, compulsive repetitive behaviors, sensory integration, and episodic memory are activated during exposure to cigarette-related cues and cigarette craving, similar to findings with other addictive substances.
Smoking withdrawal symptoms in two weeks of abstinence
TLDR
Trend analyses found that each symptom group except stimulation showed significant patterns or changes as a function of days in abstinence, and desire to smoke and psychological symptoms showed linear decreases as abstinence proceeded.
Smoking Status and Nicotine Administration Differentially Modify Hemodynamic Stress Reactivity in Men and Women
TLDR
Results suggest that cigarette smoking may act differently in men and women to increase risk for cardiovascular disease (CVD), and nicotine may exert pathogenic influences via increasing the magnitude of heart rate reactivity to stressors.
Menthol vs nonmenthol cigarettes: effects on smoking behavior.
TLDR
These findings parallel differences in physiological correlates of exposure to nicotine found in cross-sectional comparisons of African-American and White smokers and are consistent with the results of emerging laboratory investigations.

The hypothesis that dopaminergic mechanisms mediate cigarette smoking reinforcement supports the hypothesis that bromocriptine would decrease smoking behavior in humans.
