Chicago Stop Smoking Research Project

Quitting smoking is hard, and people who drink alcohol may find quitting harder than those who do not drink.
C-STOP addresses this by examining treatment strategies to determine the most effective methods to help people who regularly drink to quit smoking.

Study Facility &
Principal Investigator

The Chicago STOP Smoking Research Project (C-STOP) takes place within the Clinical Addictions Research Laboratory (CARL) at the University of Chicago. For over two decades, the CARL has conducted a variety of clinical and laboratory research to develop more effective interventions in the treatment of substance use disorders, particularly tobacco dependence.

The Principal Investigator, Andrea King, Ph.D., is a smoking cessation expert, Director of the Clinical Addictions Research Laboratory, Professor at the University of Chicago, and a licensed clinical psychologist. For decades, she has received funding from the National Institutes of Health to develop effective treatment programs for helping people to quit smoking.

"Alcohol consumption increases smoking urges and behavior, rendering those who smoke and drink at a disadvantage in smoking cessation. In C-STOP, we examine methods of quitting smoking to help determine which strategies may work best for those who drink alcohol."

" Quitting smoking has made me feel a certain level of freedom. I'm not commited or tied to a cigarette. My life is not impacted by the need to stop and go smoke. There's a certain level of financial freedom. When I quit, people were paying $8/pack, now it's $12/pack. That's a lot of money a year. I think I've saved $30,000 by quitting."

" It has to be your motivation. It has to be how bad you want to quit. What does it mean to you? Not just in the smell or the cost, but what effects you think it's having on your health or your family members. Finding your motivation is the first step to commiting to and working the program. It's the first step on the journey to living smoke-free."
