WebIn the past 20 years, liquid chromatography-mass spectrometry (LC-MS) has become a standard analytical technique in doping control and toxicology laboratories.Research groups have successfully applied it to detect substances by direct injection, or “dilute-and-shoot”-LC-MS (DS-LC-MS). WebA THC:THC-OH ratio of 2:1 is present 2 to 3 h after consumption [ 37 ], for example. The ratio between THC-COOH-glucuronide (THC-COOH-gluc) and THC-COOH varies from around 0.5 to 5. This variation depends on frequency and time since consumption.
