Habitual nicotine-seeking in rats following limited training

Authors:

Abstract
A potential reason that cigarette smoking can persist despite multiple quit attempts is that repeated voluntary nicotine intake may facilitate a transition from goal-directed to habitual behavioral control. Although accelerated habit formation for self-administered ethanol or cocaine has been previously demonstrated, this phenomenon has not been extensively studied with nicotine. We therefore examined the liability of nicotine self-administration to become habitual, while also examining that of orally consumed saccharin as an experimental control.
