Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The rapid increase of electronic nicotine delivery systems (ENDS) use by young people in the US and their potential to harm health, cause addiction, and serve as a risk for cigarette smoking or dual-use is alarming. The epidemic of ENDS use among young people in the US has been associated with the rise in popularity of ENDS products that are very efficient in delivering high doses of nicotine to users. Therefore, the investigators propose to study the effects of nicotine reduction (NR) on young ENDS users as a potential regulatory strategy to reduce the addictiveness and use of ENDS. The proposed studies are directly responsive to research priories identified by the FDA and specified in this RFA under Addiction; studying the "Impact of changes in tobacco product characteristics (e.g. nicotine formulation) on dependence". This project aims to provide an overview of this project's rationale significance divided into 1) scientific rationale and regulatory implications; 2) the need to respond to the rising trend of ENDS use among young people in the US; 3) the importance of reducing the addictiveness of ENDS; 4) the strength of our clinical and analytical lab approach for regulatory purposes; and 5) the strengths and weaknesses in the rigor of prior research about NR for ENDS.
