Brief Summary:

The purpose of this study is to determine whether sampling nicotine replacement treatments (NRTs) is superior to learning about them by computer. Testing also covers preferences among the treatments. Subjects will be enrolled veterans who smoke.

Hypothesis: Direct experience ("sampling") of NRTs will increase knowledge about NRTs, motivation/confidence, use of NRTs and quit attempts in contrast to learning about NRTs by computer.


Condition or disease Intervention/treatment Phase
Smoking Drug: Nicotine gum - 2 mg and 4 mg Drug: Nicotine lozenges - 2 mg and 4 mg Drug: Nicotine inhaler (4 mg yield) - low and high "dosage" by frequency of puffing Other: Computer learning Not Applicable

Detailed Description:
The study was designed to compare sampling of several nicotine replacement treatments (NRTs) in contrast to a computer learning control. The NRTs include: 2 dosages of nicotine gum, 2 dosages of nicotine lozenges and 2 dosages of oral nicotine inhalers. In the sampling group, each participant tries each of the 6 NRTs for 3 minutes. In the control, the individuals read about the treatments. Dependent measures include: quit attempts, use of NRTs, preferences among NRTs, and learning and motivation.

Arm Intervention/treatment
Active Comparator: Nicotine Replacement Treatment (NRT) Sampling

Sampling = 3 minute testing of each of 6 NRTs (3 forms x 2 dosages)

2 mg and 4 mg nicotine gum; 2 mg and 4 mg nicotine lozenges; frequent and infrequent puffing on a nicotine inhaler (can yield 4 mg from 10 mg device).

Drug: Nicotine gum - 2 mg and 4 mg
Other Name: Nicorette gum

Drug: Nicotine lozenges - 2 mg and 4 mg
Other Name: Nicorette Commit lozenges

Drug: Nicotine inhaler (4 mg yield) - low and high "dosage" by frequency of puffing
can yield 4 mg from 10 mg device - infrequent and frequent puffing
Other Name: Nicotrol

Sham Comparator: NRT Computer Learning
Computer learning: learning about 6 NRTs (3 forms x 2 dosages) by computer only
Other: Computer learning



Primary Outcome Measures :
  1. Quit Attempts, Use of NRTs, Preference Among NRTs [ Time Frame: At testing, at follow-up ]
    In addition to quit attempts, use of NRTs, and preference among NRTs, we also planned to assess learning and changes in motivation at all visits. Unfortunately, the study was terminated due to common comorbidities among the Veterans that precluded entry into the study. Due to the consequent small sample size, we did not analyze any data.
