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.

Progressing from Evidence to Action
A large body of research on crime and justice is available, yet it can take years for findings to influence practice in the field. During a recent panel at NIJ’s 2023 National Research Conference, researchers and practitioners shared ideas and discussed practical steps and promising new approaches to inspire change. Three guests join the show to continue their conversation: Dr. Tamara Herold, a senior advisor to NIJ, hosts Dr. Shon Barnes, the police chief of the Madison (Wisconsin) Police Department, and Dr.
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.

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.
