Role played by narcotics laboratories in the campaign against drug abuse and drug trafficking: a view from a developing country.

The narcotics laboratory at the national level identifies drugs for abuse and their accompanying substances in suspected samples, determines the purity and the possible origin of illicit drugs, carries out drug-related research, particularly on new sources of drugs liable to abuse, and, when required by the police or courts of law, provides supportive expertise in drug trafficking cases. Precaution must be taken to ensure that samples to be examined are representative. The university is a particularly appropriate setting for the location of a narcotics laboratory, especially if such a laboratory carries out complex work requiring assistance from other professional disciplines. Before new laboratory equipment is purchased, a careful study of requirements and financial resources should be made to ensure economical and optimum utilization of such equipment. In some situations the use of simple techniques, such as thin-layer chromatography, can be sufficient, while in others more sophisticated techniques may be required. Appropriate training of personnel is of particular importance for the effective functioning of a narcotics laboratory. The laboratory of the Department of Toxicology and Forensic Chemistry, University of Buenos Aires, provides for the training of personnel at three levels: The first level consists of basic training, which includes the use of kits for rapid identification of drugs in field conditions, for personnel from the police, gendarmerie, prefecture, customs and other agencies which deal with drug problems, but which have no previous skills in laboratory techniques; The second level is provided for professional laboratory personnel and usually lasts six months; The third level consists of two years' postgraduate university training for students who are expected to carry out complex laboratory work; an additional year is provided for trainees who are expected to assume responsibility in a laboratory unit.

Jimson weed seed toxicity in cattle.

A subacute experiment was undertaken for 14 days. The results obtained from these studies suggest that: 1) unless a highly Jimson weed seed contaminated feed is ingested (greater than 0.09% of body weight) or force fed, death should be a rare consequence of Jimson weed seed contamination; 2) Jimson weed seed toxicity in cattle as a result of feed contamination appears a self-limiting problem (rumen atony and anorexia prevent further intoxication until the blood levels of alkaloids are reduced to allow normal ruminant intestinal function); 3) cattle may exhibit signs of atropine toxicity at contamination levels of 881 seed/kg of feed or higher; 4) rumen fluid from heifers fed diet containing 4,408 Jimson weed seed had the greatest VFA concentration change from day 0 to 7; 5) in vitro fermentation of diets resulted in no difference in IVDMD values, but VFA concentration values tended to increase with increased concentrations of Jimson weed seed in the diet.
