Increasing evidence-based substance use interventions globally: The National Institute on Drug Abuse postdoctoral fellowships.

As of April 2020, 121 individuals from 47 nations had completed 124 NIDA International Program INVEST Drug Abuse Research Fellowships. This is the first comprehensive effort to assess the fellowships from the combined perspectives of career outcomes, migration patterns, publications, cost per publication, and funding. We searched electronic sources such as university websites, ResearchGate, LinkedIn, PubMed, and NIH databases to find current curriculum vitae, journal articles published in 2018 and 2019, and funding records.
