Resumen de A laboratory approach to the control of cocaine in Bolivia
Of the 4,196 samples of drugs seized and analysed at the Toxicology Laboratory of the National Bureau for the Control of Dangerous Substances during the period 1975 - 1982, 3,768 samples (89.8 per cent) contained coca paste, cocaine hydrochloride or related substances. Most of the samples analysed contained coca paste and came from La Paz, Santa Cruz and Cochabamba. With a slight exception in 1980, the number of samples increased steadily over an eight-year period. The increase in the number of seizures of cocaine-related substances was a result of the growth in the illicit production of these substances, which began to assume larger dimensions in 1976. In many areas, coca-paste and cocaine-related problems are growing out of all proportion. The smoking of cigarettes that contain a mixture of tobacco and coca paste, popularly known as pitillos,is the most common form of drug abuse.
