Clinical Addictions Research Laboratory

About Us

The Clinical Addictions Research Laboratory (CARL) was incepted in 1997 under the direction of Andrea King, PhD, Associate Professor in the Department of Psychiatry.

The overarching mission of CARL is two-folded:

a). to investigate factors that lead to excessive use of alcohol, tobacco, and other substances, and factors involved in increased risk for the development of substance use disorders

b). to develop more effective interventions in the treatment of substance use disorders, particularly tobacco dependence.

This web site provides a brief overview of the mission of CARL as well as some background information on each of our ongoing research studies. If you are interested in enrolling in any of these studies, links are provided for secure online surveys to get you started.

Current Research Studies

  • Chicago Social Drinking Project
    This is an experimental and longitudinal study of 190 social drinkers in the Chicagoland area. The aim is to assess social drinkers' responses to several commonly used substances, including stimulants, alcohol and sedatives. The study is currently in the follow-up phase, where participants complete interviews on a quarterly basis about their alcohol, tobacco, substance use, moods, and stress levels.

  • Chicago STOP Smoking Research Project (C-STOP)
    • This study examines the efficacy of an investigational study drug in combination with standard treatment of a nicotine patch and behavioral counseling on quit rates in a stop-smoking trial. The study is actively recruiting 324 adult smokers who desire to quit smoking. The study will enroll participants from June 2006 to August 2009. All treatment is provided at no charge and there is compensation for travel and other expenses.

  • Social Smoking Moods and Behaviors Study
    • This laboratory study examines the cognitive and mood effects of several classes of substances, such as alcohol, stimulants and sedatives. Social smokers (those who are not nicotine dependent) engage in two laboratory sessions where they may smoke one or more cigarettes. Subjects complete study measures at various intervals in the sessions. There is financial compensation and travel reimbursement for participation. ***Sorry, but enrollment for this study is now closed***

  • Social Smoking Brain Imaging Project
    • In this study, we use a non-invasive, advanced brain imaging technology of functional Magnetic Resonance Imaging (fMRI) to examine specific brain regions associated with social smokers' cognitive and mood effects of alcohol, stimulants or sedatives. Subjects will view images on a small screen and provide subjective reports and breath tests at several intervals. The total time in the fMRI scanner is less than one hour. ***Sorry, but enrollment for this study is now closed***
