The NIJ Forensic Technology Center of Excellence hosted the JustScience podcast from 2017 to 2025. NIJ has posted episodes that were released from 2022 and 2025 and will post the remaining episodes over the coming months. 

Cannabinoid Conundrums Webinar Series Expert Panel

August 2023

As evident by the Cannabinoid Connundrums webinar series, the rapidly changing world of cannabinoids offers many conundrums. To tackle some of these questions, Dr. Ruth Winecker led a panel discussion with Dr. Ed Cone, Dr. Nathalie Desrosiers, Mr. Justin Poklis, and Mr. Nelson Santos. This diverse slate of thought leaders includes experts in analytical chemistry, forensic toxicology, clinical research, and drug chemistry. This webinar was hosted by the NIJ Forensic Technology Center of Excellence on August 3, 2023. 

Cannabinoid Pharmacology: Three Decades of Controlled Human Cannabinoid

August 2023

Controlled drug administration studies are valuable tools for acquiring a detailed understanding of the pharmacodynamic and pharmacokinetic profiles of cannabinoids. ∆9-tetrahydrocannabinoid (THC) is the primary psychoactive cannabinoid in cannabis with the potential to negatively impact cognitive and psychomotor performance and workplace safety. These studies establish behavioral and subjective effect profiles while simultaneously collecting pharmacokinetics data.

Vaping in the Weeds: The Merging of the E-cigarette and Cannabis Industries

June 2023

This presentation describes the nature of the merge of the e-cigarette and cannabis industries. Quality assurance issues as a result of the absence of regulation and oversight is described. Cases of self-reported adverse events and the challenges of cannabis product analysis are also discussed.

This webinar was hosted by the NIJ Forensic Technology Center of Excellence on June 29, 2023. 

Development of Analytical Methods for Measuring Δ9 THC in Cannabis Products

June 2023

With the passage of the 2018 Agricultural Improvement Act (Farm Bill), forensic laboratories have been tasked with differentiating seized cannabis samples as either hemp or marijuana. The new legislation declassified hemp as a Schedule 1 drug substance and defined it as cannabis containing 0.3 % or less of decarboxylated-Δ9-THC (total Δ9-THC). The National Institute of Standards and Technology (NIST) has been working to help forensic laboratories with these challenging measurements through the development of extraction protocols and analytical methods.

Just Embracing Imperfection in Forensic Science

June 2023

In episode three of our Resilient Leadership mini season. Just Science sat down with Jody Wolf, Crime Lab Administrator for the Phoenix Police Department, Tim Scanlon, President of Forensic Analysis Consulting and Training LLC, and Mikayla Martin, Forensic Scientist at RTI International, to highlight the impact of human factors on forensic DNA interpretation. Human Factors Research is a discipline that examines concepts like undue influence, employee wellness and human error, which impact the decisions that forensic science practitioners make on a daily basis.

Just Collaboration in Forensic Research

June 2023

In episode two, of our Resilient Leadership mini Season, Just Science sat down with Henry Maynard to discuss the American Society of Crime Laboratory Directors, also known as ASCLD Forensic Research Committee. As researchers work to create better tools and technologies for the forensic science community, it is crucial that they are able to consult with practicing forensic professionals to better understand their needs and experiences.

All Is Not Pot That’s Green: An Overview of THC Isomers

June 2023

THC isomers, also known as THC analogs or semi-synthetic cannabinoids, are structurally related to Δ9-tetrahydrocannabinol (Δ9-THC) and have similar toxicity and impairing effects. A recent study indicated that Δ8-THC use was around 27% of marijuana use, based on detection and ratios of cannabinoid metabolites in workplace drug testing. Other analogs of interest include hexahydrocannabinol (HHC) and THC-O. THC isomers are generally perceived as legal and are also seen in states with legal marijuana.

Just Thriving in a Forensic Workplace

June 2023

This podcast episode was recorded at the 2023 American Society of Crime Laboratory Director Symposium in Austin, Texas, themed Resilient Leadership. This mini season will tease out what resiliency looks like in the forensic science community with a range of subject matter experts. Today, we'll be discussing a practical guide for employee wellness. Here to guide us in our discussion is Jamilah Dick and Meredith Rosenberg from the New York City office of Chief Medical Examiner. 

Just Workplace Stress And Its Impact On Decision-making In Forensics

May 2023

In this episode, Just Science sat down with Dr. Mohammed Almazrouei, a forensic practitioner with the Abu Dhabi Police, to discuss his dissertation work, which examines how workplace stressors may affect decision making in the field of forensic science. In their daily jobs, forensic science practitioners are tasked with making countless decisions that can make a large impact on people's lives. As a result of this experience, Dr. Almazrouei conducted a pivotal research study to examine how stress affects the way that forensic practitioners make these important decisions. Listen along as Dr.

Low Prosecution Rates in Sexual Assault Cases: Can We Make Sustainable Improvements?

April 2023

Dr. Julie L. Valentine provides background information on the challenges in tracking prosecution outcomes in sexual assault cases of adult victims. Research utilizing the National Institute of Justice Sexual Assault Nurse Examiner Practitioner Toolkit in two Utah counties is presented. Variables predicting prosecution are be explored. Participants are invited to consider societal, structural, and legislative barriers to prosecution of adult sexual assault cases faced in their jurisdiction to encourage multidisciplinary collaboration.

Just DNA Searches in CODIS

April 2023

In episode three of our 2023 Sexual Assault Awareness Month mini season, Just Science sat down with Orlando Salinas, Lieutenant Trampas Gooding, and Jennifer Pollock from the Texas Department of Public Safety to discuss how statutes regarding lawfully owed DNA and familial DNA searches are utilized in sexual assault investigations. When an unknown DNA profile is found in samples collected within a sexual assault kit, the unknown profile is searched within national DNA databases such as the combined DNA index system, also known as CODIS.

Touch DNA Evidence Collection in Sexual Assault Cases

April 2023

Dr. Julie L. Valentine introduces the application of touch DNA in sexual assault cases through a case study. A literature review on touch DNA is summarized to provide contextual information and research on touch DNA analysis findings in groping sexual assault cases is discussed. The webinar concludes with recommendations for multidisciplinary partners to collect, submit, and analyze evidence in sexual assault cases for touch DNA.

This webinar was hosted by the NIJ Forensic Technology Center of Excellence on April 18, 2023.

Solving Violent Crime Through Lawfully Owed DNA: Outcomes of Efforts to Address Missed DNA Samples

April 2023

This presentation explores the issue of lawfully “owed” DNA, which is a DNA sample from a qualifying offender who should have their DNA sample in CODIS (based on applicable state law), but from whom a sample has never been collected or submitted to a lab for testing.
