Assessing the Use of Electronic Cigarettes (E-cigarettes) as a Harm Reduction Strategy
The purpose of this study is to examine the feasibility of using e-cigarettes as a method for harm reduction and the effects of providing e-cigarettes (or placebo e-cigarettes) on smoking outcomes.
Participants will be randomized to receive either e-cigarettes with nicotine cartridges or e-cigarettes with placebo cartridges, and followed for 3 weeks.
研究概览
详细说明
This pilot study will be a two-arm, randomized controlled trial.
The investigator will randomize 40 participants into each intervention arm.
Participants will be randomized to one of the two arms: e-cigarettes with nicotine cartridges or e-cigarettes with placebo cartridges (0mg).
Participants and research assistants will be blind to the allocation of nicotine or placebo e-cigarettes as there are no difference in appearance or odor of the mist emitted from the e-cigarettes with and without nicotine containing cartridges.
Participants will be asked to track their nicotine use via text message.
All participants will receive a 20-30 minute behavioral counseling consultation with a trained tobacco counselor.
Counselors will review each participant's smoking pattern and offer tailored behavioral and environmental change strategies including specific smoking reduction strategy options.
Participants will be given a supply of e-cigarettes and followed for 3 weeks
