Brief summary

This study examines the effects of e-cigarette (EC) flavors among adults with opioid use disorder (OUD) receiving buprenorphine treatment who currently use e-cigarettes. Participants will smell and rate 11 EC flavors based on appeal, sensory characteristics, and likelihood of future use. Researchers will examine how different flavor profiles influence the appeal and reinforcing effects of ECs in this population. The goal is to identify EC flavors that may enhance the acceptability of ECs as a potential harm-reduction strategy among adults with OUD receiving buprenorphine treatment.

Detailed description

This study examines the effects of e-cigarette (EC) flavors among adults with opioid use disorder (OUD) who are receiving buprenorphine treatment and currently use e-cigarettes. Participants will complete a brief session in which they will smell and rate 11 EC flavors based on their appeal, sensory characteristics, and likelihood of future use. Researchers will examine how different flavor profiles influence the appeal, positive subjective effects, and reinforcing potential of EC flavors in this population. The goal of the study is to identify one or more EC flavors that may enhance the acceptability and reinforcing effects of ECs as a potential harm-reduction strategy among adults with OUD receiving buprenorphine treatment.

Design outcomes

Primary

MeasureTime frameDescription
Perceived SweetnessBaseline sessionPerceived sweetness of each e-cigarette flavor will be assessed using a one-item VAS ranging from "Not sweet at all" to "Extremely sweet," with higher scores indicating greater perceived sweetness.
Perceived Coolness/FreshnessBaseline sessionPerceived coolness/freshness of each e-cigarette flavor will be assessed using a one-item VAS ranging from "Not cool/fresh at all" to "Extremely cool/fresh," with higher scores indicating greater perceived coolness/freshness.
Perceived Flavor StrengthBaseline sessionPerceived flavor strength will be assessed using a one-item VAS ranging from "Very weak" to "Very strong," with higher scores indicating greater perceived flavor strength.
Perceived Harshness/IrritationBaseline sessionPerceived harshness/irritation of each e-cigarette flavor will be assessed using a one-item VAS ranging from "Not harsh/irritating at all" to "Extremely harsh/irritating," with higher scores indicating greater perceived harshness/irritation.
Flavor LikingBaseline sessionFlavor liking will be assessed using a one-item VAS ranging from "Not at all" to "Extremely," with higher scores indicating greater liking of the flavor.
Likelihood of Future UseBaseline sessionLikelihood of future use will be assessed using a one-item VAS ranging from "Not at all" to "Definitely," with higher scores indicating greater likelihood of future use of the flavor.
