title: [Detection of cannabinoids in urine].
abstract: Described in the paper are results of comparative examination of urine by the methods of immunochromatographic express analysis (ICA), fluorescence-polarization immune analysis (FIA) and of thin-layer chromatography (TLC) made for the purpose of detecting consumers of hemp products. A high specificity and a good sensitivity of the methods were demonstrated, which is a basis for using them as preliminary tests in detecting cannaboids and their metabolites in urine. The methods were evaluated quantitively and qualitatively versus the etalon method of chromato-mass-spectrometry. A possibility was pointed out to apply the methods of ICA and TLC as system analysis in the determination of 11-nordelta-9-tetrahydrocannabinol-9-carbonic acid in urine of marijuana users.
