About
Freidoon Erdmann is a forensic toxicologist whose research has made significant contributions to the detection and quantification of drugs and their metabolites in biological matrices. His work centers on developing and validating analytical methodologies for forensic laboratories, with a particular emphasis on cannabinoid analysis and multi-drug screening techniques. Erdmann's most impactful contribution is his development of an automated liquid-liquid extraction GC/MS method for determining THC and its metabolites — 11-OH-THC and THC-COOH — from blood serum, a study that has garnered 35 citations and addressed a critical need in routine forensic toxicology practice. Complementing this work, his 2016 research on automated GC/MS determination of THC, cannabinol, and cannabidiol in hair samples further advanced cannabinoid testing capabilities. His earlier 2002 study on simultaneous screening and detection of drugs in small blood samples and bloodstains, with 34 citations, demonstrated his long-standing commitment to practical, efficient forensic methods applicable to real-world casework. Across his career, Erdmann has consistently pushed toward greater automation and analytical precision, helping forensic laboratories worldwide improve throughput and reliability in drug testing — work of growing importance given evolving legal landscapes surrounding cannabis and substance use.
