Official title

Dual Use of ENDS and Combustible Cigarettes: Shared, Distinct, and Cross-Conditioned Processes

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study investigates the degree to which shared behavioral processes underlie combustible cigarette (CC) and electronic nicotine delivery system (ENDS) use in young adult dual users of these products in both the laboratory and natural environment. The primary processes examined by this study are cue-reactivity, attentional bias, and affect. Laboratory hypotheses are: (1) cue exposure will elicit craving of both CC and ENDS in the laboratory and that product-specific cues will elicit stronger craving for the affiliated products; (2) visual probe effects indicating attentional bias in the laboratory will be observed for smoking and vaping images; and (3) cross-conditioning from the first hypothesis will be associated with heaviness of use of CC and ENDS and product choice. Natural environment hypotheses are: (1) presence of tobacco-related cues in the natural environment will elicit craving and use of these products; (2) reactivity to cues, attentional bias, and cross-product conditioning assessed in the laboratory will be associated with craving and use of tobacco products over and above the effects of cues in the natural environment; and (3) negative affect will strengthen these associations.
