About the Presentation: Stress is a commonly reported precipitant of relapse to substance use. There is a growing recognition of the need to understand psychobiological and physiological alterations in the stress response among chronic drug users, and to determine how they may precipitate relapse. Novel methods of assessment including wearable sensor technology provide means to assess the dynamic relationship between stress and craving in the field. I will present in this seminar recent results from our laboratory focusing on biological and psychological response to stress among dependent smokers and share results demonstrating that steep decline in cortisol concentrations during early abstinence and hyporesponsiveness to stress predict shorter time to relapse. I will also present preliminary results from studies using wearable sensors to examine effects of stress in the lab and in the field. Future research in assessment and intervention with stress and tobacco addiction will be presented.
