Outcomes
Primary Outcome Measures
Change in daily quantitative cigarette smoking
Quantitative tobacco cigarette smoking will be measured by experimenter-administered rating scale for 30 days prior to treatment through 6 month follow-up.
Change in exhaled carbon monoxide (CO) levels

5. Study Description
Brief Summary
This is a pilot human experimental study to evaluate whether the use of an e-cigarette affects lung function, exhaled CO levels, and quantitative tobacco cigarette consumption in active tobacco smokers. Subjects recruited from the Winchester Chest Clinic (WCC), Adult Primary Care Clinic (PCC) and the Smilow Cancer Hospital Smoking Cessation Service will be randomized to 1 of 2 groups: (1) nicotine patch and intensive counseling (standard care) plus nicotine e-cigarette; (2) nicotine patch and intensive counseling plus non-nicotine e-cigarette.
