title: [Analytical exploration of drug addiction].
abstract: The natural and synthetic substances most frequently leading to drug addiction are described. They include cannabis, opium and cocaine with their respective derivatives. The authors insist on the problems encountered by analytical chemists when they examine urine samples containing these substances, owing to their metabolic degradation and to interferences between lawful and unlawful drugs. The limitations imposed by these problems to an unambiguous interpretation of the results obtained are defined, but they do not throw any doubt on the value of these investigations.
