A procedure has been developed to extract and recover minute amounts of delta-9-carboxytetrahydrocannabinol (THC-COOH) from urine. A new non-isotopic internal standard is introduced to permit a chromatographic assay of the metabolite. The method affo

The presence of acetylcodeine as an impurity in illicit heroin preparations has been demonstrated by the detection of codeine in hydrolyzed samples. The method described here, using thin layer chromatography, showed that acetylcodeine per se can be s
