Sex-specific effects of chronic stress prior to cocaine exposure on cue- vs drug-induced relapse after prolonged abstinence.

ABSTRACT: The comorbidity between cocaine use disorder (CUD) and trauma/stressor-related disorders suggests a connection between neurophysiological changes induced by stress and those that lead to cocaine use. Due to the unexpected and sometimes uncontrollable nature and timing of stressful life events, their capacity to induce drug use poses a significant challenge for the administration of cocaine relapse therapy. This study aims to investigate the impact of chronic stress applied prior to cocaine acquisition on the development of cocaine-seeking behavior after different periods of drug abstinence in male and female rats. Rats were exposed to five days of inescapable footshocks (chronic stress) before undergoing extended access cocaine self-administration. Different groups then underwent forced ab
