Evaluation of tetrahydrocannabinolic acid (THCA) synthase polymorphisms for distinguishing...
The Controlled Substances Act (CSA) classifies marijuana (Cannabis sativa) as a Schedule I illicit drug. However, the recent Agriculture Improvement Act of 2018 (U.S. Farm Bill) removed hemp from the definition of marijuana in the CSA, making it a legal crop. As a result, many he...
Developmental validation of an efficient differential separation method incorporating the...
The differential separation method is key to recovering a DNA profile of the sperm donor from sexual assault samples. However, low numbers of spermatozoa from the perpetrator are often swamped by the victim's epithelial cells or lost during the separation process, with the s...
Quantitative analysis of smokeless powder particles in post‐blast debris via gas...
Forensic analysis of smokeless powder particles recovered from the debris of an improvised explosive device can provide information about the type of smokeless powder used and can aid investigation efforts. In this study, quantitative methods were used to yield information about ...
Smartphone‐based colorimetric determination of gamma‐butyrolactone and gamma...
Gamma‐hydroxybutyrate (GBH) is a popular recreational drug. Its strong sedative and amnesic effects have led to drug‐facilitated sexual assaults, poisonings, overdose, and death. As a result, legislation has restricted its availability leading to GHB, consumers switching to its p...
Microbial community succession of submerged bones in an aquatic habitat
After death, microbes (including bacteria and fungi) colonize carrion from a variety of sources during the decomposition process. The predictable succession of microbes could be useful for forensics, such as postmortem submersion interval estimation (PMSI) for aquatic deaths. How...

A comparison of three decalcification agents for assessments of cranial fracture...
The extraction of mineral calcium from bone by decalcification is a critical step in the preparation of histological samples for light microscopy. This study assessed the time required for complete decalcification and the resultant histomorphological preservation of bone histomor...

Hashish seizures in Algeria over the 2019–2020 period: The rise of potent hashish hybrids
In Algeria, hashish is by far the most common illicit drug. This study explores Algerian hashish over a two‐year period (2019–2020). A total of 2583 hashish samples from 1707 seizures for a total quantity of 108 tons were analyzed using a validated high‐performance liquid chromat...
Mapping the neurocircuitry of impulsive aggression through the pharmacologic review of...
Impulsive aggression, in contradistinction to premeditated aggression in humans or predatory aggression in animals, corresponds to defensive aggression in animal models. At the core of the neurocircuitry of impulsive aggression, from murine to feline to human species, it is the m...
