Abstract

Rationale: Delay discounting, or the devaluation of delayed outcomes, appears to play an etiological role in tobacco and other substance-use disorders. Objectives: No human studies to our knowledge have been designed to examine whether experimental reductions in delay discounting produce concomitant reduction in drug use. Methods: Using methods from prior studies on delay discounting and obesity, we examined the effects of episodic future thinking (EFT; a form of mental prospection) on delay discounting and cigarette self-administration in smokers. Results: Consistent with prior data, EFT significantly reduced both delay discounting (Cohen’s d effect size = 0.65) and the number of cigarette puffs earned in a cigarette self-administration task (d = 0.58). Conclusions: The effects of EFT on delay discounting generalize to smokers; EFT also reduces laboratory-based cigarette self-administration. Potential mechanisms of EFT’s effects are discussed as well as implications of EFT for clinical treatment of substance-use disorders.
