Influence of Hormones on the Brain in Smokers with a Regular Menstrual Cycle

Site Image

Study Overview

The purpose of our research is to examine the influence of hormonal status on brain responses to smoking cues. Magnetic resonance imaging, or MRI, will be used to measure brain responses at three distinct time points during your menstrual cycle, across approximately three separate menstrual cycles. We are interested in the brain and behavioral responses of women who smoke cigarettes while viewing videos or pictures of a variety of things, including smoking. Participants in the study will be healthy women, between the ages of 18-45, with a normal length menstrual cycle, who smoke cigarettes. Participants will need to be using a form of birth control that is non-hormonal. This is NOT a QUIT smoking study.
