Tobacco regulatory policies can have unanticipated consequences; therefore, methods that would permit prospective estimates of the effects of potential tobacco regulations are necessary for the development of tobacco regulatory science. The goal of this project is to experimentally assess how smokers purchase and consume reduced-nicotine cigarettes and how this is related to nicotine content and absorption. The proposed projects can directly inform tobacco regulation by providing estimates of the real-world effects of novel policies.

Primary Outcome Measures:
  • Cigarette Purchase Task [ Time Frame: 10 minutes after cigarette administration ]
    The Cigarette Purchase Task is a behavioral economic measure of abuse liability that consists of a series of hypothetical questions asking participants to indicate how many cigarettes they would purchase for their own consumption across a range of cigarette prices.

  • Change in blood nicotine content [ Time Frame: Prior to and 0, 5, 10, 20, 35, and 50 minutes after cigarette administration ]
    Blood will be collected throughout each session and analyzed for nicotine content. The change in blood nicotine content over the course of the session will be compared among the six sessions where different cigarettes were administered.

Estimated Enrollment: 58
Study Start Date: January 2017
Estimated Study Completion Date: July 2020
Estimated Primary Completion Date: July 2020 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Single arm
All participants will complete the same experimental events across 6 laboratory sessions.
Drug: SPECTRUM cigarettes
Across six laboratory sessions, participants will consume 10 puffs of either their usual brand of cigarette (one session) or a SPECTRUM cigarette (five sessions) with a nicotine yield varying from 0.03 to 0.70 and either menthol (TPMF codes NRC 103, NRC 201, NRC 301, NRC 401, and NRC 501) or tobacco (TPMF codes NRC 102, NRC 200, NRC 300, NRC 400, and NRC 500) flavor, depending on preference. This will be followed by the collection of blood nicotine content and a cigarette purchase task.
