Study summary

The purpose of this study is to determine if changing the timeframe (relative to cue presentation) at which the nicotine lozenge is given can attenuate the increase in symptoms of tobacco craving and withdrawal that occur when smokers are presented with smoking cues. In this cross-over study, all subjects attend three laboratory sessions at which either nicotine lozenge or placebo is given prior to presentation of smoking cues or after presentation of smoking cues. The order in which the three conditions will be presented are randomized.

What researchers measure

Primary outcomes

  1. Craving Symptom Severity Score Assessed Via Questionnaire

    Craving as assessed via the craving question on the Minnesota Nicotine Withdrawal Scale. The score range is from 0 (no craving) to 4 (severe craving). The outcome measure is the change in craving score from before cue exposure to craving score after cue exposure.

    Time frame: approximately 15 minutes

  2. Withdrawal Symptom Severity Score Assessed Via Questionnaire

    Withdrawal as assessed via the Minnesota Nicotine Withdrawal Scale. The score range is from 0 to 28 with higher scores indicating more severe withdrawal symptoms. The outcome measure is the change in withdrawal score from before cue exposure to the withdrawal score after cue exposure.

    Time frame: approximately 15 minutes
