What the study is about

The proposed project aims to refine and test a novel biobehavioral smoking cessation intervention that integrates the strategic application of olfactory stimulation to reduce cigarette craving with an established smartphone-based smoking cessation application. The specific aims of this study are: (1) refine the design and methodology of our olfactory stimulation delivery system (OSDS) and (2) compare, in a pilot randomized controlled trial (RCT), the effects of a smartphone based app for smoking cessation (Smart-T) with and without the OSDS on smoking cessation outcomes.

Being studied: Ad Libitum Use followed by Instructed Use of the Inspire Device; Instructed Use followed by Ad Libitum Use of the Inspire Device; Smart-T Smoking Cessation App with the Inspire Device Condition; Smart-T Smoking Cessation App Without the Inspire Device Condition; Nicotine replacement therapy (NRT); Inspire Device

Conditions: Nicotine Dependence
