In this specialized workshop intended for forensic science service providers (FSSPs), we explore the increasing adoption of Time-of-Flight and Quadrupole Time-of-Flight Mass Spectrometry (TOF/QTOF-MS) technologies within forensic laboratories. The session provides an in-depth examination of various critical stages, encompassing planning, validation methodologies, analytical techniques, data review processes, and report generation. Subject matter experts disseminate knowledge and share first-hand experiences related to the utilization of TOF/QTOF-MS technology.

As evident by the Cannabinoid Conundrums 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.

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.

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.

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.

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.

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.
