Brief Summary

The universe of tobacco products is expanding, with new noncombustible products gaining popularity even as the reduction in prevalence of cigarette smoking slows or stalls. E-cigarettes, or Electronic Nicotine Delivery Systems (ENDS), are the most prevalent of these emerging noncombustible products. With sales increasing rapidly and more efficient pulmonary delivery devices under development, ENDS are likely to play an increasing role in the future tobacco market. Little is known about the cognitions and behaviors leading to or sustaining ENDS use. Smokers may use ENDS to subvert smoking restrictions, to reduce perceived smoking harms, or for smoking cessation. Evidence about ENDS use is emerging from national surveillance and laboratory research, but the majority of information on ENDS is limited to retrospective surveys and convenience samples of White male ENDS users. The investigators research suggests Black smokers are less likely than White smokers to try and be current ENDS users, perhaps due to a greater degree of perceived harm associated with ENDS, a preference for menthol, or cultural norms. Thus, it is timely and critical to study how all smokers, including Blacks and menthol smokers, experience and initiate ENDS use employing valid, innovative research methods.

Outcome Measures

Primary Outcomes (1)

  • Cigarette Use

    Change in the average number of cigarettes per day comparing average cigarettes per day on study day 6 (last day of cigarette-only use) to average cigarettes per day on study day 7 (first day of e-cigarette and cigarette use).

    Study Day 7, Week 2

Study Arms (1)

Ecig group 1

EXPERIMENTAL

On study day 6, we provided participants with two NJOY King 5-packs of cigalike e-cigarettes and asked them to take at least three puffs a day to ensure that they had some exposure to the product in the first week. On day 13, we gave participants two additional NJOY King 5-packs and instructed them to use or not use the e-cigarettes as they wished.

Other: Ecig group 1

Interventions

E-cigarettes were 3% nicotine and of tobacco or menthol flavor, depending on participants' usual flavor preference.
