The legalization/decriminalization of cannabis starting in Colorado and passage of the 2018 Farm Bill has led to a dramatic rise of synthetic analogues related to delta 9-Tetrahydrocannabinol (Delta 9-THC) and Cannabidiol (CBD). These non-traditional cannabinoids, including delta 8-THC, delta 10-THC, and varying delta 8-THC, delta 9-THC, and delta 10-THC analogues, are readily available in a variety of products found in varying retail outlets and via the World Wide Web.
The rise of these cannabinoids has led to various analytical challenges, deriving from their similarity in structure, often being isobars, and lack of reference material. Many of these compounds have limited pharmacological data available. Biomarkers are often not characterized or available.
Presented is how the Laboratory for Forensic Toxicology Research at Virginia Commonwealth University has utilized a Shimadzu GCMS-QP2020 and an LCMS-8050 in an attempt to keep pace with the evolving cannabinoid reality. Simple chemical and biological techniques as well as analytical methods of these nontraditional cannabinoids will be discussed.
