A Survey and Comparison of Heroin Seizures in Israel During 1992 by Fourier Transform Infrared Spectrometry
During 1992, a survey was performed on heroin powder exhibits seized throughout Israel. The main objectives were to detect salt forms and additives and compare the powders for intelligence and investigation purposes. A total of 3817 exhibits were scanned by FTIR; five major groups were distinguished: heroin free base, heroin base with caffeine, heroin base with paracetamol (acetaminophen), heroin base containing both caffeine and paracetamol, and a mixture of heroin base, heroin HCl and caffeine. In addition, 419 exhibits collected during a two month period were compared amongst themselves and categorized into sub-groups based on the similarity of their spectra. Based on this data, it was possible to define 116 different sub-groups, of which 56 sub-groups contained from 2 to 47 samples. Of the total number of cases tested, 78% were in the weight range 1 mg-1 g, that is, user quantities. Results were tabulated on both a geographical and monthly basis. Differences were found in the distribution of additives between different geographical areas of the country.
