Detaljeret beskrivelse

PRIMARY OBJECTIVES:

I. Assess the abuse liability (appeal and sensory effects) of IQOS. II. Examine the puffing topography of IQOS.

SECONDARY OBJECTIVES:

I. Evaluate the impact of flavor on the sensory effects, appeal, and puffing topography of IQOS.

II. Evaluate the effect of perceived harm on IQOS use behavior.

EXPLORATORY OBJECTIVE:

I. Examine acute changes to pulmonary health associated with IQOS use.

OUTLINE: Participants are randomized to 1 of 2 arms.

ARM I: Participants use IQOS HeatSticks (flavor matched to their usual cigarette) as much as desired (ad lib) over 60 minutes during laboratory visit 1. At least forty-eight hours later, participants smoke their usual brand cigarette (UBC) ad lib over 60 minutes during laboratory visit 2.

ARM II: Participants smoke their UBC ad lib over 60 minutes during laboratory visit 1. At least forty-eight hours later, participants use IQOS HeatSticks (flavor matched to their usual cigarette) ad lib over 60 minutes during laboratory visit 2.

Foranstaltningsbeskrivelse
Tidsramme
Product Appeal
Tidsramme: Minute 5 of product use session, Minute 35 of product use session, Minute 60 of product use session
Participants will complete the Appeal and Sensory Quality questionnaire. This questionnaire will ask participants to rate each study product for appeal characteristics such as liking, willingness to use again, flavor intensity, pleasantness of taste, etc. on a scale of 0 (not at all) - 100 (extremely). Higher scores indicate greater liking, willingness to use again, flavor intensity, etc.
Minute 5 of product use session, Minute 35 of product use session, Minute 60 of product use session
Product Sensory Attributes
Tidsramme: Minute 5 of product use session, Minute 35 of product use session, Minute 60 of product use session
Participants will rate sensory attributes using the Appeal and Sensory Quality questionnaire. This questionnaire will ask participants to rate each study product for sensory attributes such as harshness, coolness, sweetness, etc. on a scale of 0 (not at all) - 100 (extremely). Higher scores indicate greater harshness, coolness, sweetness, etc.
Minute 5 of product use session, Minute 35 of product use session, Minute 60 of product use session
Economic demand breakpoint
Tidsramme: Minute 60 of product use session
The price point at which a participant is no longer willing to pay for a stick of the study product will be determined by using a cigarette purchase task questionnaire.
Minute 60 of product use session
Satisfaction and psychological reward
Tidsramme: Minute 5 of product use session, Minute 35 of product use session, Minute 60 of product use session
Satisfaction and psychological reward of study product use will be measured by the Modified Cigarette Evaluation Questionnaire (mCEQ). The mCEQ asks questions relating to satisfaction of using the study product on a scale from 0 (Not at all) - 6 (Extremely).
