  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: CBT Treatment
Participants receive Cognitive behavioral therapy (CBT). Participants will receive 4 one hour CBT treatments.
Behavioral: Cognitive behavioral therapy
Therapy focused on explaining the physiological and psychological effects of nicotine. Training is focused on adherence to smoking instructions, physiological and psychological effects of nicotine, reviewing reasons for quitting, and coping with smoking urges. Smokers will be asked to begin smoking on a set schedule leading up to their quit day.
Other Names:
  • CBT
Active Comparator: Control Group
Participants receive health education treatment. Participants will attend treatment sessions that match the CBT Treatment arm with respect to time and contact.
Behavioral: Health education
Therapy that provides health education on the importance of healthy eating. Participants will be instructed to smoke as usual.
No Intervention: Control Group - Scans
Participants in this new arm to the study will receive no intervention and will receive three scans.
