title: [Current approaches to analysis of narcotic drugs in biological substances].
abstract: A method of analysis of basic narcotic drugs in urine is described. It consists in isolation by solid phase extraction, derivation and identification by gas chromatography with mass-selective detector. The approaches applied in the above method can be used for analysis of narcotic drugs undetectable by preliminary investigations as well as for urine examination for pharmacological or other biologically active substances.
