Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is focused on characterizing the toxic and carcinogenic potential of the Standardized Research E-cigarette (SREC) developed by the National Institute on Drug Abuse. In the environment of continuously changing e-cigarette market, SREC was developed as a model e-cigarette that will remain available for an extended period of time and can be used as a bridging element in various studies aimed at evaluating the value and limitations of e-cigarettes as tobacco risk reduction tools. Our overall goal is to generate initial reference data on chemical exposures and associated effects in smokers switching to SREC.
