NCT07564648

Brief Summary

This randomized, double-blind, crossover human laboratory study compares the abuse liability of cigarettes containing menthol and non-menthol cigarette variants, using the participant's usual brand menthol cigarette as a within-subject reference. Participants complete standardized laboratory smoking sessions, behavioral economic tasks, and a naturalistic observational period. The study examines differences in nicotine delivery, smoking behavior, and subjective effects across cigarette types in laboratory and real-world contexts.

Outcome Measures

Primary Outcomes (1)

  • Plasma nicotine (Cmax)

    Nicotine delivery will be summarized by Cmax, the maximum nicotine concentration observed in the plasma samples for each participant.

    During Phase 1 and 2 smoking sessions, assessed up to 3 weeks

Secondary Outcomes (15)

  • Appeal ratings (Labeled Hedonic Scale)

    During Phase 1 and 2 smoking sessions and Phase 1 and 3 EMA, assessed up to 3 weeks

  • Puff topography

    During Phase 1 and 2 smoking sessions, assessed up to 3 weeks

  • Sensory effects (general Labeled Magnitude Scale)

    During Phase 1 and 2 smoking sessions and Phase 1 and 3 EMA, assessed up to 3 weeks

  • Nicotine craving and withdrawal (Questionnaire of smoking urges)

    During Phase 1 and 2 smoking sessions and Phase 1 and 3 EMA, assessed up to 3 weeks

  • Nicotine craving and withdrawal (Minnesota Nicotine Withdrawal Scale)

    During Phase 1 and 2 smoking sessions and Phase 1 and 3 EMA, assessed up to 3 weeks

  • +10 more secondary outcomes

Study Arms (3)

Study Cigarette A

EXPERIMENTAL

Participants smoke one Study Cigarette A during one Phase 2 laboratory session (10 puffs over 5 minutes), with puff topography and serial plasma nicotine sampling. Subjective effects, the Cigarette Purchase Task, and the Cross-Price Elasticity Task are completed during the session. Order of exposure to Study Cigarettes A, B, and C is randomized.

Study Cigarette B

EXPERIMENTAL

Participants smoke one Study Cigarette B during one Phase 2 laboratory session (10 puffs over 5 minutes), with puff topography and serial plasma nicotine sampling. Subjective effects, the Cigarette Purchase Task, and the Cross-Price Elasticity Task are completed during the session. Order of exposure to Study Cigarettes A, B, and C is randomized.

Interventions

Exhaled carbon monoxide breath testing and serial 3 mL blood samples collected via indwelling intravenous catheter at -5, +5, +15, +30, and +60 minutes relative to smoking initiation during each laboratory visit.

Study Cigarette AStudy Cigarette BStudy Cigarette C

Self-report questionnaires administered at laboratory visits to assess the subjective effects of each cigarette (e.g., product appeal, sensory perception, satisfaction) using validated instruments such as the Modified Cigarette Evaluation Questionnaire.

Study Cigarette AStudy Cigarette BStudy Cigarette C

A behavioral economic task administered after each laboratory smoking session. Participants indicate how many cigarettes they would purchase across varying price points to characterize demand for each study product.

Study Cigarette AStudy Cigarette BStudy Cigarette C

A behavioral economic task administered after each Phase 2 smoking session. Participants choose between their usual brand menthol cigarette (price increasing) and the study product (fixed price), characterizing substitutability.

Study Cigarette AStudy Cigarette BStudy Cigarette C

Brief electronic surveys completed three times daily for one week during Phase 1 (usual brand cigarette use) and Phase 3 (preferred study cigarette use), capturing product use, craving, withdrawal, mood, and subjective effects in the natural environment.

A concurrent choice task administered at the final laboratory visit.
