Cocaine availability has been increasing in Spain in the past few years. A review of all the toxicological analyses carried out at the Madrid Department of the Instituto Nacional de Toxicología, with subjects who had died of drugs from 1990 to 1992, found 533 persons who had cocaine in their blood and/or tissues; 450 (84%) deaths involved cocaine and heroin together whereas 83 (16%) deaths involved cocaine with an absence of heroin. This paper reports the circumstances, cocaine and benzoylecgonine concentrations in the blood and other toxicological findings for the two major groups of deaths where cocaine was found with an absence of heroin, i.e., possible overdose cases (35 cases) and traffic accidents (23 cases).
