Purpose
Smoking remains a leading cause of preventable disease and premature death worldwide. Approximately 1 out of every 5 deaths is associated with cigarette smoking, and roughly half of all daily smokers will die prematurely from tobacco-related illness. Reducing the nicotine in cigarettes to the point that they are rendered non-addictive can potentially be an effective public policy measure that can significantly reduce tobacco-related mortality and morbidity by decreasing the initiation of smoking and promoting cessation. The Family Smoking Prevention and Tobacco Control Act (FSPTCA) enables the FDA to establish tobacco product standards including placing limits on the allowable nicotine content of cigarettes. Currently, no reduced nicotine cigarettes are available that will allow studying the feasibility of this policy measure. The National Institute on Drug Abuse has contracted with Research Triangle Institute to assist in the development of cigarettes with varying nicotine content that can be made available to researchers. They have established a contract that will result in the manufacture of 9 million cigarettes to be distributed to the research community. Prior to full production, the palatability and nicotine intake of these cigarettes in smokers must be determined.

Primary Outcome Measures:
- Comparison of Urine Cotinine Levels and Total Nicotine Equivalent (TNE) [ Time Frame: Baseline (Day 1) Compared to Week 1 ] [ Designated as safety issue: No ]Two urine cotinine levels are taken, one at baseline and one at week 1, to assess cotinine levels for nicotine exposure. TNE is the sum of nicotine, cotinine, trans 3'-hydroxycotinine and their respective glucouronide conjugates.
Secondary Outcome Measures:
- Fagerstrom Test of Nicotine Dependence (FTND) Response to Test Cigarettes [ Time Frame: First Visit (Day 1) ] [ Designated as safety issue: No ]Questionnaire: At 1st Visit - Fagerstrom Test of Nicotine Dependence (FTND); score at baseline indicates level of tobacco dependence, scores range from 0 (low) to 10 (high).
- Change from Baseline of Modified Cigarette Evaluation Scale Response to Cigarettes [ Time Frame: Baseline (Day 1) Compared to Second Visit (Week 1) ] [ Designated as safety issue: No ]Modified Cigarette Evaluation Scale [CES] is a 100 mm visual analog scale (0=not at all or very little nicotine; 100=extremely or high in nicotine) of 20 questions assessing different dimensions of responses to usual brand cigarettes (e.g., psychological reward, satisfaction and aversiveness) and includes additional 5 point likert-type questions (definitely agree to definitely disagree) on perceptions of satisfaction and willingness to use the product.
- Change from Baseline of Multiple Choice Procedure Response to Test Cigarettes [ Time Frame: Baseline (Day 1) Compared to Second Visit (Week 1) ] [ Designated as safety issue: No ]Questionnaire: Multiple Choice Procedure [MCP], assesses cigarette demand and sensitivity to increases in cigarette costs. (If you were given the choice between the following amounts of money and a pack of the study cigarette you just smoked which would you prefer?)
- Change from Baseline of Perceived Health Risk Scale Response to Test Cigarettes [ Time Frame: Baseline (Day 1) Compared to Second Visit (Week 1) ] [ Designated as safety issue: No ]Questionnaire: Perceived Health Risk Scale asks subjects to rate their perception of health risks of the study product to which they have been randomly assigned compared to their usual tobacco product This is a 100 mm visual analog scale; 0=very low risk of disease, 100=very high risk of disease.
- Comparison of Number of Cigarettes Smoked [ Time Frame: Daily During One Week ] [ Designated as safety issue: No ]Subjects were given a daily diary to collect the number of study and/or conventional cigarettes they have smoked each day. Cigarettes smoked (both usual brand and experimental) in a given week were summed over the first 7 reported days. If the number of cigarettes smoked was missing for 1 day, the average of the other days in that week was used in its place.

Detailed Description:
Phase 3: This descriptive study will use a between subjects, double blind design. This study will test 3 nicotine levels of nicotine, tar and ventilation. Subjects and research assistants will be blind to the cigarette type.
