Brief Summary

This nationwide telephone and mail- based research study will recruit 1,400 cigarette smokers who are not motivated to quit to test the effects of a marketed oral, non-combustible smokeless tobacco product on cigarette smoking behaviors. It will also track the participants' usage patterns of the smokeless tobacco product. Half of the participants will receive a new, potentially safer tobacco product during the first six weeks of the study, and half will not. During this six-week period, each participant will complete three brief phone interviews. After this first six week period, participants will complete 6 other brief follow-up interviews, where they will answer questionnaires about their smoking habits.

Outcome Measures

Primary Outcomes (1)

  • Quit Attempts and Abstinence

    % of study participants making a quit attempt or staying abstinent from smoking during the study Notes: Floating abstinence: Any 7-day period of non-smoking, ever within study. PPA: point-prevalence abstinence

    From study enrollment through end of one-year follow up

Study Arms (2)

PREP (Potentially Reduced Exposure Product) Group

EXPERIMENTAL
Drug: Potentially Reduced Exposure Product (PREP): a smokeless, spit-free tobacco product

cigarette group

NO INTERVENTION

Interventions

The PREP Group will be given a sample supply of a PREP product that is already on the market. It is unclear if it is safer than cigarettes, and that is why it is classified as a Potentially Reduced Exposure Product. It provides both nicotine and tobacco in the form of a pouch that can be thrown away after used. Unlike chewing tobacco, there is no need for spitting with this product. There are multiple flavors and participants will have his/her choice of preferred flavor. This group will be asked to sample the product and use it in several ways, but whether a participant uses the product or not is up him/her.
