About

Gustav Sundqvist is a forensic toxicologist whose work centers on the precise detection and quantification of cannabinoids in biological matrices. His primary research focus is the development and validation of advanced liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods for analyzing tetrahydrocannabinol (THC), its major metabolites, and related compounds in whole blood. Sundqvist's most cited paper, "Quantification of THC, metabolites, and related compounds in whole blood using LC-MS/MS" (2022), provides a robust analytical framework that improves sensitivity and specificity for forensic and clinical applications. This contribution is critical for accurate interpretation of cannabis exposure in driving under the influence (DUI) cases, workplace testing, and pharmacokinetic studies. While his citation count is still emerging, the methodological rigor of his work positions it as a foundational reference for laboratories seeking reliable cannabinoid quantitation. Sundqvist’s achievements include advancing the field’s ability to distinguish between recent and past cannabis use, directly impacting legal and public health decisions. His research continues to shape best practices in forensic toxicology, offering a clear, reproducible path for analyzing complex cannabinoid profiles in whole blood.
