Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in UrineTotal Nicotine Equivalent (TNE) Between Baseline and Week 1

    Two urine TNE levels are taken, one at baseline and one at week 1, to assess TNE levels for nicotine exposure. TNE is the sum of nicotine, cotinine, trans 3'-hydroxycotinine and their respective glucuronide conjugates. Values reported in nmols/ml.

    Second Visit (Week 1) minus Baseline (Day 1)

Secondary Outcomes (3)

  • Responses on Modified Cigarette Evaluation Scale

    Baseline usual brand cigarettes (Day 1) compared to when using study cigarettes (Week 1)

  • Change From Baseline of Perceived Health Risk Scale Response to Test Cigarettes

    Baseline (Day 1) Compared to Second Visit (Week 1)

  • Comparison of Number of Cigarettes Smoked

    1 week

Study Arms (3)

Arm 1 Low Level Nicotine Cigarette

EXPERIMENTAL

(0.4 mg/g)

Other: Low level nicotine cigarette

Arm 2 Intermediate Nicotine Level Cigarette

EXPERIMENTAL

(5.7-5.8 mg/g)

Other: Intermediate nicotine level cigarette

Arm 3 High Level Nicotine Cigarette

EXPERIMENTAL

(11.4-12.8 mg/g)

Other: High level nicotine cigarette

Interventions

smoke the study cigarette exclusively for one week

Arm 1 Low Level Nicotine Cigarette

smoke the study cigarette exclusively for one week

Arm 2 Intermediate Nicotine Level Cigarette
