Does Switching to Nicotine Containing Electronic Cigarettes Reduce Health Risk Markers

Tobacco Dependence Clinical Trial

Official title:
Does Switching to Nicotine Containing Electronic Cigarettes Reduce Health Risk Markers

Clinical Trial Summary

The overall goal of this project is to understand the likely health effects of cigarette smokers switching to a Standardized Research Electronic Cigarette (SREC) and to assess the role of nicotine delivery on switching and acceptability as well as markers of health outcomes. Current smokers who meet all eligibility criteria will completely switch from their combustible (regular) cigarettes to an electronic cigarette (SREC) that either contains 58 mg/ml of nicotine or 0 mg/ml of nicotine in the liquid. The investigators' hypothesis is that attempting to switch to a SREC will result in a reduction in markers of harms to health, as compared with the baseline (smoking) measures. The investigators also hypothesize that nicotine-containing SRECs will facilitate switching from smoking more efficiently than zero nicotine SRECs and will result in a significantly greater improvement in markers of health risk, but will result in higher ratings of dependence on the SREC (as compared to the zero nicotine SREC).

Clinical Trial Description

This project is a prospective parallel-group randomized double-blind, placebo-controlled study in which 104 current smokers who are willing to completely switch from their regular cigarettes to an electronic cigarette (SREC) for 6 weeks will be randomly allocated to use a SREC containing either 58 or 0 mg/ml nicotine in the liquid. Following randomization to their assigned study product, participants will be supported in their switching efforts with regular contacts both in person at the Penn State Milton S. Hershey Medical Center and over the phone. The main measures will be recorded at two in-person visits after the randomization (switching) visit: (a) 3 weeks after switching and (b) 6 weeks after switching. All participants will also be followed up at 10 weeks by phone to identify whether they have continued to use electronic cigarettes or regular cigarettes and to assess their motivation to change. ;
