Impurities, adulterants and diluents of illicit heroin in Denmark (Jutland and Funen)

The contents of impurities, adulterants and diluents in 77 samples of illicit heroin were determined by a combination of high-performance liquid chromatography and gas chromatography. The origin of each sample was characterized by calculating the content of the opium alkaloids in relation to the heroin content. The routes of distribution were compared by determination of the contents of caffeine, procaine and sugars. The results were used as a "chemical fingerprint" of each sample. The results indicate that it is difficult to prove, with certainty, that two samples are identical. However, in most cases, by determining the amounts of impurities, adulterants and diluents in heroin samples, it will be possible to ascertain whether two samples are different and, in many cases, to determine with reasonable certainty whether two samples are identical.     

Methodology and interpretation of morphiate detection in urine samples

In TLC screenings of 335 urine samples taken because of suspicion of heroin consumption, positive evidence of morphine was found in about 50% of the cases, which was confirmed without exception by gas chromatography-mass spectrometry. In 66% of the positive cases, morphine and codeine were found; in about 31% only morphine was found, and the median value of 0.4 mg/l free morphine and 1.0 mg/l conjugated morphine was considerably lower than in the whole collection of samples. Comparison of the codeine/morphine quotients (Q), especially the free bases, proves that the groups of heroin/morphine or codeine consumers can be distinctly differentiated. The critical conditions of the conjugated bases worked out by Dutt et al. (1983) proved to be right. Using the equation Qf less than 0.5 square root c, a boundary condition for the free flare bases can also be developed, which is dependent on the sum of the codeine and morphine concentrations and which proves heroin/morphine consumption with 98% certainty.

Component analysis of illicit heroin samples with GC/MS and its application in source identification

A novel method based on GC/MS and GC for component analyses of seized illicit heroin was established by using SKF525A as an internal standard. The main components in illicit heroin products such as heroin, O3-acetylmorphine, monoacetylcodeine, and O6-acetylmorphine were determined quantitatively and the organic adulterants such as paracetamol, acetaminophen caffeine and theophylline were detected qualitatively using the developed method. With these obtained data, 500 seized illicit heroin samples were divided into nine groups. The decomposition pattern of heroin was studied. The dependencies of both the decomposition pattern and the content ratios of monoacetylcodeine to heroin and monoacetylcodeine to O6-acetylmorphine on the source of the seized illicit heroin were observed. This information was used to develop a novel method for its source identification. The examination results were in agreement with the practical cases, thus providing significant information for detection of criminal cases involving illicit heroin.     

Illicit drug abuse in the Marmara region of Turkey

Data on the analysis of 840 illicit drug samples of a total weight of 749.677 kg, confiscated in the Marmara Region, Turkey, from January 1986 to April 1987 is presented. The majority (82.3%) of all cases examined by the Division of Narcotic Drugs Research Laboratories of the Council of Forensic Medicine of Turkey, related to Cannabis products. Heroin represented 16.7% and all other controlled drugs made up the remaining 1%. From the 691 samples analyzed, 43.15% was Cannabis plant material. From the 140 illicit heroin samples analyzed by capillary gas chromatography, 61% had a diacetylmorphine content between 30 and 48%. O-6-monoacetylmorphine was detected in 43% of the samples ranging from 0.4 to 8.6%. Almost half (46.6%) of all heroin samples contained procaine ranging from 0.7 to 22%.     

Is There a Relationship Between Street Heroin Purity and Drug‐Related Emergencies and/or Drug‐Related Deaths? An Analysis from Vienna,Austria*

This study examines the quality of street heroin seized in Vienna in 1999 and whether there was a relationship between the purity of street heroin and the number of heroin-related emergencies as well as the number of heroin-related deaths. Street heroin confiscated by the Viennese police, run-sheets of drug-related emergencies, and postmortem reports of drug-related deaths in Vienna in 1999 were analyzed. A total of 415 retail samples with a total weight of 128.02 g contained a median percentage of 6.5% diacetylmorphine (range: 0.0-47.0%). All the samples contained a diluent, mainly lactose, as well as adulterants, such as caffeine and/or paracetamol. During the study period, 75 heroin-related deaths and 387 heroin-related emergencies were registered in Vienna. Time-series analysis revealed no statistically significant relationship between the rate of heroin-related incidents and the diacetylmorphine concentration of street heroin samples confiscated in Vienna in 1999. The widely held belief that the number of heroin-related deaths could be explained simply through fluctuations in the purity of street heroin could not be substantiated, even though the results of this study do not rule out an association between the purity of heroin and heroin-related deaths/emergencies.     

Heroin abuse and a gas chromatographic method for determining illicit heroin samples in Singapore.

The abuse of heroin (diacetylmorphine) in Singapore escalated sharply in 1975 and 1976, as indicated by the 35-fold increase in the number of heroin seizures and the 20-fold increase in the urine samples containing morphine since 1974. A rapid and simple GC method has been described to estimate diacetylmorphine (and caffeine). Monoacetylmorphine and acetylcodeine may be ascertained by an additional step involving acetylation. All gas chromatograms of a large number of samples analyzed consistently had the same pattern, indicating that they possibly had a common origin. This GC "fingerprint," together with the quantitative data, appears to be characteristic of the illicit Asian or Chinese type of heroin found in Singapore. The proportions of the four major ingredients in some twelve typical samples have been tabulated. Statistical data confirming the accuracy and reproducibility of the analytical method have also been presented.     

Histologic findings of the sinus node and the perinodal area in street heroin addicts, victims of sudden unexpected death

Sudden unexpected death is frequent in street heroin addicts. We conducted a histologic study of the sinus node (SN) to offer some evidence about the possible arrhythmogenic cause of death. Postmortem coronary angiography and microscopic examination of the SN and the perinodal area were performed in 50 heroin addicts (group 1) and in 50 nonaddicts (group 2), all men (16-40 years old). In heroin addicts, fatty and/or fibrous tissue replaced SN tissue in 21 cases (42%). Perinodal infiltration was found in 15 cases (30%). Fibromuscular dysplasia in branches of the sinus node artery (SNA) was found in eight cases (16%). Inflammation with focal and/or diffuse concentration of round cells was detected in the SN in 22 cases (44%). Old mural thrombi were also found in 13 cases (26%). The histologic changes in the SN and perinodal area offer an explanation about the possible mechanism of arrhythmia and sudden death in this population.     

The introduction of CCTV and associated changes in heroin purchase and injection settings in Footscray,Victoria, Australia

Objectives

In June 2011, closed-circuit television (CCTV) was introduced in Footscray (a suburb of Melbourne, Australia) to help deter street-based drug trading. We investigate whether there were subsequent shifts in the settings (e.g., street, house) in which heroin was purchased or injected by people who inject drugs (PWID).

Methods

Using heroin purchase data from the Melbourne Injecting Drug User Cohort Study, multinomial logistic models with fixed effects for CCTV introduction were used to estimate the percentage of: (1) heroin purchased on the street, from mobile dealers and in house settings; and (2) heroin injections occurring in street, car, public toilet, and house settings. Displacement effects were investigated with a logistic model capturing the likelihood of traveling to Footscray to purchase heroin.

Results

Following CCTV introduction, the percentage of heroin injections occurring in public toilet settings decreased by 13 % (95 % CI ?27 %, ?0 %). This was accompanied by a non-significant increase in the percentage of heroin injections in street settings of 23 % (95 % CI ?1 %, +41 %). Changes in other settings were small and non-significant. No suburb displacement effects were found.

Conclusions

The introduction of CCTV in Footscray may have displaced PWID who previously injected heroin in public toilets to street settings. Apart from this, Footscray’s street-based heroin market operates much as it did before CCTV.
