Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.
NIJ’s forensic science research and development program focuses on basic and applied scientific research with the intent to:
- Direct the findings of basic scientific research in broader scientific fields applicable to forensic science.
- Apply forensic science research to the development of highly discriminating, accurate, reliable, cost-effective, rapid methods for the identification, analysis and interpretation of physical evidence.
- Expand the scientific basis of forensic methods.
- Produce useful materials, devices, systems or methods that have the potential for forensic application.
- Increase the body of knowledge to guide and inform forensic science policy and practice.

Cannabinoid Pharmacology: Three Decades of Controlled Human Cannabinoid
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.

Estimating Age of Death from Subadult Remains, Part 2
The long-standing problem of estimating the age and sex of subadult skeletal remains has been significantly "solved" with the advances in understanding the growth and development patterns in the skeletons of young people. This is the second half of the conversation with Kyra Stull, an anthropologist and forensic researcher at University of Nevada, Reno, Danielle McLeod-Henning, a physical scientist at NIJ, host Jim Dawson.
Vaping in the Weeds: The Merging of the E-cigarette and Cannabis Industries
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
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
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
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
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
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
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.
