This study is investigating the use of a novel technology for assessing cigarette smoking in the natural environment. The PACT uses data gathered from respiration and hand movements to determine when an individual is smoking a cigarette. Additional data on smoking topography and location within the environment are also collected. Data collection for this project began in fall 2017 and is ongoing.
Alcohol and Cigarette Dual Cues (ACDC) Study
This study is examining the ability of smoking and alcohol cues to elicit craving for both substances, and the associations between drug craving, seeking, and consumption behaviors. Using the CBUCC (Choice Behavior Under Cued Conditions) procedure, single drug cues (smoking, alcohol, neutral) and combined cues (smoking + alcohol) are presented. A central question to this investigation is whether combined drug cues enhance cue-elicited craving or the reward value of these substances in a non-additive, additive, or synergistic manner. Manuscript preparation for this project is currently underway.
Impact of Cues and Abstinence in Nicotine Dependent Individuals (iCANDI)
This study is examining the effects of abstinence on the reward value of food and cigarettes. Using the CBUCC (Choice Behavior Under Cued Conditions) procedure, smokers are presented with food, drug (cigarette), and neutral cues. Craving and drug-seeking responses are measured in response to these cues under abstinence and non-abstinence conditions. Data analysis for this project is currently underway.
