Translational Neuropsychopharmocology Research of Nicotine Addiction


This double-blind placebo-controlled study is investigating the effects of combining two medications, Varenicline (commonly known as Chantix) and N-acetylcysteine, on smoking behavior in daily cigarette smokers who are interested in quitting smoking. The study consists of 10 visits over 6 weeks and includes two fMRI scans.

An fMRI pilot study of the effects of Clavulanic Acid on cigarette withdrawal


This study is looking at the effects of Clavulanic Acid (a drug used in antibiotics) on brain activity and smoking withdrawal.  Participants do not need to be looking to quit but must be willing to make a quit attempt during their participation.  This study involves 6 visits over 2 weeks and includes two fMRI scans.

Effects of filter ventilation on sensory response, smoking, topography and inhalation

This observational/nontreatment study examines how ventilation levels in cigarette filters influences the appeal of the product as well as risk perceptions and the intent to purchase. This study is completed in 2 visits and will involve smoking various cigarettes and completing surveys and questionnaires. Participants will be current cigarette smokers that are not looking to actively make a quit attempt within 30 days.

Examining the effects of Theta Burst Stimulation on corticothalamic mediated inhibitory control and smoking relapse vulnerability

This study is looking at the effects of TBS (theta burst stimulation) on smoking relapse behavior in daily adult cigarette smokers. Study participation consists of 4 visits over 2 weeks and includes two sessions of TBS and three fMRI scans.

Neural mechanisms mediating appetitive regulation and smoking in nicotine addiction

This treatment study is examining the effects of a behavioral intervention on smoking behavior in daily adult cigarette smokers who are interested in quitting smoking. Participants will either receive 4 weeks of MORE (Mindfulness Oriented Recovery Enhancement) or CBT (Cognitive Behavioral Therapy), and then make an attempt to quit smoking. The study will take place over the course of 8 weeks and will include group therapy sessions and two fMRI scans.
