Smokers with a better mood experienced a higher nicotine boost from cigarettes. This finding suggests psychological factors influence nicotine intake, though the effect size was small.

Area of Science:

  • Addiction Science
  • Psychology
  • Pharmacology

Background:

  • Nicotine boost, the rise in blood nicotine after smoking, varies individually.
  • Understanding predictors of nicotine boost is crucial for smoking cessation research.

Purpose of the Study:

  • To identify demographic, smoking status, and psychological predictors of nicotine boost.
  • To explore the relationship between positive affect and nicotine boost in smokers.

Main Methods:

  • Assessed nicotine boost by measuring plasma nicotine levels before and after ad libitum cigarette smoking.
  • Included 190 treatment-seeking smokers, collecting demographic and smoking status data.
  • Controlled for baseline cotinine levels and Federal Trade Commission nicotine delivery ratings.

Main Results:

  • Positive affect (mood) was a significant positive predictor of nicotine boost.
  • The model explained only a small proportion (5%) of the variability in nicotine boost.
  • Demographic and smoking status variables were not significant predictors in this model.

Conclusions:

  • Psychological factors, specifically positive affect, play a role in individual nicotine boost.
  • Further research is needed to elucidate the complex interplay of psychological, physiological, and cigarette-specific determinants of nicotine boost.
