NIDA Standardized Research Electronic Cigarette (SREC) for Clinical Research

Project Overview

The goal of the SREC Project is to facilitate clinical research into the impact of e-cigarettes on public health. We achieved this by developing a standardized device with a data package sufficient to support FDA authorization for clinical investigations. The SREC produces a consistent, well-characterized aerosol, and was designed to serve as a standard for clinical studies without concern of unreported modifications being made to the device during the course of a multi-year study. The SREC is intended for use in NIH-funded human subject studies. Requests to purchase for any other use will be reviewed on an individual basis by NJOY, LLC.

Nicotine Pharmacokinetics

Information is available upon request by researchers for use where needed for NIH grant application submissions or IRB review.

Other Information

  • The SREC cannot be used in human studies with a primary aim of eliminating nicotine use, i.e., nicotine cessation studies. If employed in this manner FDA would consider the SREC to be a drug /device combination, requiring an Investigational New Drug (IND) application approval. At the current time, the SREC Product Master File does not meet IND requirement guidelines.
  • In order to use the SREC in human subject studies, an Investigational Tobacco Product (ITP) authorization must first be obtained from the FDA.  Guidance on how to file an ITP
    • When filing the ITP application, you will need to include a Letter of Authorization (LOA) from NJOY, LLC.
    • The LOA indicates that your application has NJOY’s permission to cross-reference the SREC Tobacco Product Master File, which is on file with The FDA Center for Tobacco Products.
    • You should request the LOA when you contact NJOY, LLC, regarding your purchase of SREC.
    • Submit the ITP application to:

      Center for Tobacco Products
      Food and Drug Administration
      10903 New Hampshire Avenue
      Attn: Document Control Center
      Building 71, Room G335
