  Purpose

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.

Primary Outcome Measures:
  • Prevalence of smokeless tobacco product use in the smokeless tobacco group [ Time Frame: From study enrollment through end of one-year follow up ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Changes in smoking behavior [ Time Frame: From study enrollment through end of one-year follow up ] [ Designated as safety issue: No ]
    We will determine changes in each of the following outcomes: 1) cigarette smoking, 2) motivation to quit, 3) confidence to quit. Cigarette smoking will be determined as the average cigarettes per day over the prior 7 days. Change in each outcome will be measured at 3 timepoints, each measured as change since baseline: a) end of tobacco product sampling period, b) 6-month, and c) 12-month follow-up.


Estimated Enrollment: 1400

Arms Assigned Interventions
Experimental: PREP (Potentially Reduced Exposure Product) Group Drug: Potentially Reduced Exposure Product (PREP): a smokeless, spit-free tobacco product
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.
