Heroin Overdose Deaths and Heroin Purity Between 1990 and 2000 in Istanbul,Turkey*

Abstract: Turkey has continuously experienced problems with abuse of, and addiction to, opium derivatives. In this study, we analyzed the relationship between heroin overdose deaths and the characteristics of seized opium derivatives. Data were gathered from the Council of Forensic Medicine of the Ministry of Justice in Istanbul from 1990 to 2000. There were 636 heroin‐related deaths during this period, 595 of which were classified as heroin overdose deaths. Mean crude and weighted heroin purities remained relatively constant and were calculated to be 46% (57–34%) and 51% (39–59%), respectively. The weight of heroin and the number of heroin seizures, but not the heroin purity, were significantly associated with the number of heroin‐related deaths. Prevention strategies are needed to reduce the number of deaths caused by overdoses in countries situated on drug trafficking routes. These strategies should focus on drug trafficking, by providing increased levels of, and support for, law enforcement, stopping the supply of precursor chemicals, and combating corruption among border officials.

海洛因依赖及其相关法医学问题

近年来,随着吸毒人数的增加以及非法成瘾物质的种类日趋繁多,成瘾性药物的使用越来越成为世界上普遍存在的严重社会问题,而阿片的半合成品——海洛因更因为其高纯度及相对较低的价格被广泛使用。

Heroin fatality due to penile injection

Death due to heroin overdose and/or rapid injection of heroin is a frequent occurrence among opioid addicts. We present an unusual case of heroin fatality due to the injection of the drug in the penis. Blood, urine, bile, and vitreous humor concentrations of morphine were 0.68, 0.49, 0.32 and 0.062 microg/ml, respectively. Ethanol was detected at concentrations of 104, 124, 106, and 94 mg/dl in the blood, urine, bile, and vitreous humor, respectively. The cause of death was determined to be due to heroin and ethanol intoxication.     

Juvenile parole policy in the United States: Determinate versus indeterminate models

This paper presents an overview of eight approaches in juvenile parole policy for terminating, extending, and discharging youths from juvenile parole or aftercare. These types were derived from the results of a national survey of juvenile parole policy in the United States. This survey was sent to the departments of correction, youth service bureaus, and legislative service agencies for the 50 states. The survey sought comparative data on trends in substantive and procedural approaches for handling parole duration and discharge issues for juvenile offenders. These trends are evaluated in relation to movements toward formalism in corrections, recent reforms in juvenile sentencing, standards promulgated by various standard-setting groups, and recent shifts in juvenile justice philosophy in the United States.     

甲基苯丙胺和海洛因标准物质研究进展

甲基苯丙胺和海洛因是禁毒斗争的重要打击目标。毒品检测实验室在对甲基苯丙胺、海洛因相关检材进行定性定量分析时,必须依靠相应的高纯度标准物质作为分析参照,才能得出正确的检测结果。目前,尚未出现针对甲基苯丙胺和海洛因标准物质相关研究进展的报道。国内外现有生物基质甲基苯丙胺标准物质以及甲基苯丙胺纯度标准物质,可应用于体内外甲基苯丙胺的检测鉴定工作。其中,生物基质包括冻干尿液、毛发以及冷冻人体血清。海洛因除纯度标准物质外,已制备出了¹³C标记的海洛因标准物质,¹³C标记后的标准物质较氘代衍生物具有更高的分析精度。制备后的标准物质需经气相色谱-质谱法、液相色谱-质谱法、核磁共振波谱法、傅里叶变换红外光谱法等进行结构确认,同时通过气相色谱、液相色谱等不同定量分析方法进行量值。本文对上述国内外甲基苯丙胺和海洛因标准物质的研究情况进行概述,并展望了未来的研究方向。     

Postmortem Fluid Concentrations of Heroin Biomarkers and Their Metabolites

Only limited data exist concerning the utility of complementary specimens in heroin-related deaths. As such, this report employed a validated LC-MS-MS method to quantify 6-monoacetylmorphine (6-MAM), 6-acetylcodeine (6-AC), and their metabolites morphine and codeine in blood with (BN) and without preservative (B) and the additional unpreserved specimens of vitreous humor, urine, stomach contents, and bile from 20 postmortem cases in which heroin was the primary cause of death. The median concentration of 6-MAM in BN was 0.011 mg/L, B was 0.008 mg/L, urine was 0.186 mg/L, vitreous humor was 0.022 mg/L, stomach contents was 0.147 mg/L, and bile was 0.012 mg/L. Only one case was found to be positive for 6-AC in B (case 6, 0.002 mg/L), and the median concentration of 6-AC was 0.002 mg/L in BN, 0.012 mg/L in urine, 0.003 mg/L in vitreous humor, 0.057 mg/L in stomach contents, and 0.004 mg/L in bile. These findings present new information on the distribution of these analytes in complementary matrices and support their inclusion for accurately determining the role of heroin in opioid-related deaths.     

Comparative Toxicology of Intentional and Accidental Heroin Overdose*

Abstract: The demographic and toxicological characteristics of deliberate (SUI, n = 50) and accidental (ACC, n = 927) fatal heroin overdose cases were examined. SUI cases were more likely to be female, had lower body mass indices, were more likely to be enrolled in treatment and less likely to have hepatic pathology. The median blood morphine concentration of SUI cases was significantly higher than that of ACC cases (0.70 vs. 0.40 mg/L, p < 0.001). Blood morphine concentrations of >1 mg/L were seen among 38.0% of SUI cases compared to 13.9% of ACC cases. Being a member of the SUI group remained a significant independent predictor of higher morphine concentrations after controlling for the effects of potential confounders (p < 0.001), other significant predictors being the absence of alcohol (p < 0.001), the presence of methadone (p < 0.05), and the presence of cocaine (p < 0.05). The current data are consistent with the view that suicide forms a small, but distinct, category of heroin overdose cases, rather than overdose being a parasuicidal phenomenon per se.     

海洛因来源鉴定的新方法

毒品来源的鉴定是指对毒品样品中包含的来源信息进行提取拜分析,这有助于打击毒品犯罪.海洛因是危害我国的主要毒品,它的来源鉴定更引起人们的关注.本文介绍了国际上研究海洛因来源的三种方法,即研究海洛因样品中的各种有机杂质及其相对比例;研究海洛因样品中的痕量无机元素;研究海洛因及吗啡的稳定同位素相对比值.第三种方法能够反映样品的地域性特点,因而在来源鉴定方面有突出的优势.气相色谱-燃烧-同位素比值质谱法是同位素比值测定方法中用于海洛因来源鉴定的最佳手段.这一技术还可用于其他微量物证(如炸药、药品、油品等)的来源鉴别,因而在法庭科学领域内显示了广阔的应用前景.

Heroin addiction, crime and economic cost: A critical analysis

The conceptual framework for measuring the economic cost of crime is reviewed. Although this framework is generally accepted, specific applications are shown to contain conceptual errors. In the drug abuse area, where the greatest number of applications have been made, serious misapplications are documented. Because of these conceptual flaws and careless extrapolation of estimates that are hardly more than guesses, the total economic cost of drug-related crime has been greatly overestimated. The result has been to reinforce the policy emphasis on law enforcement and to mislead the public as to the important sources and magnitude of the total economic cost of drug abuse.     

同位素比值质谱法鉴别海洛因来源——1.海洛因水解制备吗啡的研究

同位素比值质谱法(IRMS)是目前鉴别缴获的海洛因来源的三种主要方法之一。用该法研究海洛因的来源应分别考虑吗啡来源地和乙酰化试剂来源二方面的因素。本文以缴获的海洛因毒品制备吗啡的方法着手,从酸性和碱性两条路线考察了海洛因水解制备吗啡的方法。研究水解的实验条件,达到了码啡90%以上的产率和95%以上的纯度。首次提出了最佳的反应参数组合,它们分别为:反应温度100℃,反应时间30min,海洛因样品(包括海洛因盐酸盐和游离碱)与盐酸的摩尔比1:3.0;反应温度100℃,时间45min,海洛因盐酸盐与KOH的摩尔比1:4.4,海洛因游离碱与KOH的摩尔比1:3.4。本文还考察了吗啡气相色谱(GC)定量的工作曲线,并对吗啡的TMS衍生物的GC、GC/MS测定结果进行了比较。
