Evaluation of Oral Tobacco as a Harm Reduction Method for Smokers

This study will be accomplished by allowing subjects to sample the products and choose one oral tobacco product that they will use instead of cigarettes for a two week period. After the two weeks, they will discontinue all tobacco use and withdrawal symptoms and abstinence rates will be observed. Subjects will attend an orientation visit where the study will be explained in detail. Interested subjects will sign a consent form and be scheduled to return for baseline measures. Subjects will have a review of medical history to verify that they are in generally good health and do not have contraindications to the study products. Eligible subjects will collect one week of baseline measures while smoking at their normal rate: measures include daily diaries of smoking, questionnaires and urine samples. At the second baseline visit, they will receive samples of the oral tobacco products. The tobacco products tested are five novel oral products recently introduced to the market: 1) Camel Snus (higher nicotine); 2) General Snus (higher nicotine); 3) Marlboro Snus (lower nicotine); and two compressed tobacco tablets, 4) Ariva (lower nicotine), or 5) Stonewall (higher nicotine). All of these tobacco products are purported to have reduced levels of tobacco-specific nitrosamines. During sample weeks, subjects will be given 10 pouches/tablets of each product in a within-subject design and instructed to use at least three of the daily products in the morning of sample day and resume smoking in the afternoon and through the following day. They will sample the next product in a similar manner. The order of product was randomized. All subjects will sample all five products. This design will allow a short, but adequate trial of each product to determine preference. After the sampling weeks, subjects will choose the product they will want to use to quit smoking. They will be supplied that product over the next two weeks. During the two weeks of product use during smoking abstinence, subjects will come to weekly clinic visits and then a follow-up visits at 1 week and a phone call at 4 weeks after the end of treatment. At baseline, and 2 weeks post cigarette cessation, subjects will bring in a urine sample from their first morning void and bloods will be drawn. At each visit, subjects will have vital signs obtained (blood pressure, heart rate, weight and carbon monoxide level), they will complete several subjective forms regarding tobacco use, withdrawal symptoms, and mood. Subjects will receive brief behavioral counseling for smoking cessation at all visits. In addition, during the sample weeks and at the end of two weeks of study product use, subjects will submit three used chews that will be sent to CDC to be analyzed for the tobacco constituents.
