Smokeless Tobacco: Changes in Behavior and Readiness to Quit

Friday, April 30, 2010  
A pilot randomized study of smokeless tobacco use among smokers not interested in quitting: Changes in smoking behavior and readiness to quit.
Carpenter MJ and Gray KM. Nicotine & Tobacco Research Advance Access published online on January 6, 2010.

This small (N=31) study examined the possible outcomes of smokeless tobacco use among smokers. The authors hypothesized that co-use of smokeless tobacco could result in either increased total tobacco exposure thus undermining motivation to quit, or decreased overall tobacco exposure thus motivating smokers to quit and enhancing cessation efforts. Smokers uninterested in quitting were randomized to receive one of two kinds of smokeless and spitless tobacco lozenges, or to continue smoking cigarettes. Lozenge use led to a significant reduction in cigarettes per day, no significant increases in total tobacco use, and significant increases in two measures of readiness to quit, as well as significant increases in self-efficacy to quit smoking. No similar changes were observed among those who continued smoking. The authors conclude that there is a need for a large randomized trial to assess the use of smokeless tobacco as a method for increasing cessation among unmotivated smokers.
