Brief Summary

The Family Smoking Prevention and Tobacco Control Act granted the FDA the authority to regulate and restrict tobacco advertising tactics that inaccurately convey reduced product risk, yet there is a dearth of up-to-date regulatory science to inform such regulations. Although the FDA has restricted use of descriptors such as "natural" and "additive-free," research shows that the tobacco industry quickly pivoted to increase use of alternative, unregulated tactics. Greenwashing is one increasingly common tobacco marketing strategy in which products are portrayed as eco-friendly and/or natural. The investigators' preliminary research indicates that greenwashing tactics may inaccurately convey modified product risk to consumers. The overarching objective of this project is to test the effect of greenwashing methods used by cigarette companies to market products on actual smoking behavior in a controlled laboratory study. The investigators' proposed research focuses on young adults (age 18-29), because this is a key age for smoking initiation and escalation, and research has found that young adults may be more susceptible than older adults to greenwashing in cigarette ads. This study will test the effect of greenwashing on behavioral economic demand and smoking topography in a laboratory-controlled cigarette self-administration study. These data will clearly connect tobacco advertising features to product risk perceptions and actual smoking behavior. This work will provide FDA with an integrated set of evidence that identifies misleading greenwashing tactics that inaccurately convey modified product risk which can be used to inform regulatory action regarding restrictions of this type of advertising.

Outcome Measures

Primary Outcomes (4)

  • Demand Intensity as Assessed by a Behavioral Economic Demand Curve

    Number of cigarette puff bouts smoked at no cost as measured by a demand curve

    Through study completion, an average of 2 weeks

  • Demand Elasticity as Assessed by a Behavioral Economic Demand Curve

    Sensitivity of cigarette consumption to changes in cost for cigarettes

    Through study completion, an average of 2 weeks

  • Cross-price Elasticity Coefficients as Assessed by a Behavioral Economic Demand Curve

    Sensitivity of cigarette consumption to changes in cost for alternative products as a linear slope.

    Through study completion, an average of 2 weeks

  • Change in Total Puff Volume as Measured by a Smoking Topography Machine

    Total cigarette puff volume in milliliters (mls)

    Days 2 and 3

Study Arms (1)

Smoking sessions

EXPERIMENTAL

This is the single arm that will go through cigarette smoking sessions

Behavioral: Smoking sessions

Interventions

Participants undergo topography and behavioral economic sessions where they can make choices to earn cigarette puffs by pulling plungers on experimental equipment
