What's Known and Unknown about Marijuana (Part One)
What's Known and Unknown about Marijuana (Part One)
Marijuana poses many challenges for researchers, law enforcement, and policy makers, challenges that fall into two fields: drug chemistry and toxicology. NIJ scientist Dr. Frances Scott joins this episode to explain the complications in drug chemistry and how difficulties defining marijuana lead to backlogs in crime labs around the country. NIJ Communications Assistant Josh Mondoro hosts.

A Data-Informed Response to Emerging Drugs
The emerging drug crisis in the U.S. touches both criminal justice and public health, and experts from both fields came together at NIJ’s 2023 National Research Conference to discuss strategies and tools to fight this problem. Dr. Frances Scott, NIJ scientist and program manager, continues the conference discussion with two fellow panelists: Ciena Bayard, the Method Development and Validation Program Manager for D.C. Office of the Chief Medical Examiner, and Haley Greene, the Deputy Epidemiologist for the Central Region for the Virginia Department of Health. Read the transcript.
