NCT03699865

Brief Summary

The purpose of this study is to look at the effects of investigational low nicotine cigarettes on young adult smokers. The investigators are interested in how using these products affects young adults' perceptions and smoking behaviors. This research may help inform the Food and Drug Administration (FDA) how best to regulate tobacco products in the future with the goal of improving public health.

Outcome Measures

Primary Outcomes (1)

  • Daily cigarette consumption

    Daily cigarette consumption will be assessed primarily by participant self-report and secondarily through collection of spent filters for all cigarettes smoked during the 35-day study period, and will be averaged across baseline and pack color periods.

    Days 0 through 40

Secondary Outcomes (3)

  • Total puff volume

    Days 0, 5, 10, 15, 20, 25, 30, 35, and 40

  • Risk perceptions

    Days 10, 20, 30, and 40

  • Harm exposure

    Days 0, 5, 10, 15, 20, 25, 30, 35, and 40

Masking Details
Participants will be informed that they will be supplied cigarettes with low nicotine content but will be blinded to exact nicotine content and unaware that within-subject, all packages will contain the same type of low nicotine cigarette

Intervention Model
FACTORIAL
Model Details: Randomized, single-blind, 2 x 4 mixed factorial design laboratory-based study manipulating: (1) cigarette pack color (4-level within-subjects factor: own brand vs. white vs. purple vs. black color), and (2) nicotine content (2-level between-subjects factor: moderate vs. very low nicotine content). All participants will provide and smoke their preferred brand for an initial 5-day baseline period, receiver their own brand free-of-charge for 5-days, and then will be randomly assigned to smoke either intermediate or very low LNC cigarettes for the study duration. We will supply participants with LNC cigarettes in three pack colors; each color will be used for a 10-day period, in counter-balanced order.
