  Purpose

The use of smokeless tobacco (ST) as a substitute for cigarette smoking has been suggested since it is considered by some to be a less harmful tobacco product (Russell, Jarvis and Feyerabend, 1980; Russell et al, 1981; Rodu, 1994). ST does not have the tar and carbon monoxide (CO) that are found in cigarette smoke. Since ST is not smoked there would be less risk of cardiovascular and lung disease. In addition the harm associated with second hand smoke would be eliminated. Although the health risks are reduced in ST users, they still exist due to the presence of nitrosamines found in ST. A better approach would be to use nicotine replacement that did not contain carcinogens, however the cost of such NRT could be prohibitive especially in third world countries where the rate of smoking is continuing to rise and the per capita income is much lower than in the United States.

Purpose: The goal of this study is to evaluate the health effects of Camel Snus, the new oral tobacco product produced by RJ Reynolds and Taboka, produced by Phillip Morris. These products are pasteurized rather than fermented and contain less moisture and salt to eliminate spitting. They will be marketed as an alternative to cigarette smoking.

Detailed Description:

Cigarette smokers (n=125) will be recruited from the local metropolitan area using multiple media outlets. Subjects who are medically and psychologically healthy will be recruited for the study. Cigarette smokers will be informed of the study over the telephone and asked to answer a brief tobacco use history and medical screening questionnaire. If subjects pass the initial screening for the study, they will be asked to attend an orientation meeting (cigarette smokers will attend separate orientations) at the Tobacco Use Research Center where the study will be explained in more detail, informed consent will be obtained and a full screening evaluation will occur. This evaluation includes the completion of several comprehensive tobacco use and social history forms and a complete physical and psychological screening.

Subjects will be required to attend the clinic once during Week 1 and once during Week 2 of the study in order to obtain baseline data. At the end of Week 2, cigarette smokers will either be randomly assigned to: 1) quit tobacco use and will be offered the choice of using nicotine gum or lozenge, depending on personal preference (n= 25) or they will be assigned to switch to: 2) Camel Snus (n=50) or 3) Taboka (n=50) for 4 weeks. During the next four weeks, subjects will be asked to attend weekly clinic visits during which time study data will be collected. After the 4 weeks of study product use, subjects will be required to taper off of the tobacco or nicotine product over the next two weeks and then cease all tobacco use by week 9. Withdrawal symptoms will be assessed at Week 8, and for the first week following cessation. Follow-up visits will be conducted 1 week (Week 9) and 12 weeks (Week 19) after completion of the study and outcome measures will be taken at that time. Blood and urine samples will be collected and analyzed for tobacco related toxicants.
