谈互联网上毒品犯罪及对策

互联网因其现代化、科学化、高效率、高覆盖及无国界等优点,迅速走进人们的生活,同时也给不法之徒进行犯罪活动提供了契机。目前通过互联网订购、销售毒品、进行在线毒品交易、提供制毒配方等互联网上涉毒案件已出现,网上毒品犯罪已成为全球毒品犯罪的最新发展动向,引起各国政府及执法部门的高度关注。     

反相高效液相色谱法同时测定人血清中氯丙嗪与氯扎平的浓度

作者建立了同时测定人血清中氯丙嗪与氯扎平浓度的反相高效液相色谱(RP—HPLC)法。以利眠宁为内标,用环己烷—乙醚(1:1)混合溶剂提取血清中氯丙嗪和氯扎平。高浓度中毒者血清(>1ug/ml)则用乙腈沉淀后直接进行色谱测定。血清中氯丙嗪、氯扎平的方法回收率乎均各为98.5±4.0(SD)%,CV4.2%;99.9±4.1(SD)%,CV4.1%。两药在血清中的最低检测浓度为10ng/ml。本法应用于临床氯丙嗪、氯扎平合用药物的血浓度监测及司法中毒案例的分析,结果满意。     

Relationships between concentrations of cocaine and its hydrolysates in peripheral blood, heart blood, vitreous humor and urine

Cocaine is known to degrade in vivo and in vitro by several hydrolytic mechanisms. A previous study found that the initial amount of cocaine added to plasma could be accounted for by summing the molar concentrations of cocaine's hydrolysis products and the cocaine remaining after hydrolysis. The present study was undertaken to investigate whether or not relationships might exist between such molar concentration sums for different postmortem bodily fluids. Determinations of cocaine, benzoylecgonine, ecgonine methyl ester, and ecgonine were performed using liquid chromatography/mass spectrometry (LC/MS/MS) with heart blood, femoral blood, vitreous humor (VH), and urine (UR). The results demonstrate a strong correlation between blood and VH concentrations (correlation coefficients of 0.88-0.94), weak correlation between the UR and blood concentrations (correlation coefficients of 0.61-0.64), and weak correlation between UR and VH concentrations (correlation coefficient of 0.59). The results demonstrate that ecgonine is a significant hydrolysate with concentrations on the same order of magnitude as benzoylecgonine. The results are consistent with rapid distribution of the parent drug and its hydrolysates in the blood and VH. The strong correlation between the blood and VH demonstrates that VH is an important medium for toxicology testing when attempting to make a determination of cocaine intoxication.     

论西部地区的禁毒情报协作——西部地区毒品犯罪对全国禁毒工作影响研究之二

毒品犯罪的特殊性决定了情报在打击毒品犯罪中的重要性,而毒品犯罪的跨区域性特点决定了加强情报合作和协作的重要性,西部地区在禁毒斗争中不仅要加强国际禁毒情报交流,也要加强各省市区之间的禁毒情报协作.这种协作的途径主要是通过推进公安情报体制的改革、建立西部地区禁毒协作机制、加强"金盾工程"建设、利用公安部驻滇禁毒联络办公室等来进行,协作的内容主要有战略性情报的交流、禁毒基础信息的共享、毒品专案侦查的情报协作等.     

Prevention science,drug abuse prevention,and Life Skills Training: Comments on the state of the science

There has been tremendous growth in the field of prevention science over the past two decades. The defining features of contemporary prevention science are high quality empirical research using rigorous and well-established scientific methods, careful hyphothesis testing, and the systematic accumulation of knowledge. One area where substantial progress has been made is in our understanding of the etiology and prevention of tobacoo, alcohol, and illicit drug abuse. In this paper, we review the growth in prevention as a scientific enterprise, discuss advances in drug abuse prevention research, and review the effectiveness of one approach to the problem of adolescent drug abuse, the Life Skills Traning (LST) program, and the methodological strengths of the LST evaluation research. In addition, we provide a response to criticism regarding two types of data analysis in evaluation research, and show that these analyses can help address a number of important research questions with implications for theory and practice. First, the analysis of high fidelity subsamples can address research questions about the importance of program implementation fidelity; and second, composite measures of concurrent tobacco, alcohol, and marijuana use (i.e., polydrug use) are useful in testing research questions about program effects on more serious levels of drug involvement. With an increasing number of ramdomized controlled trials underway, the field of prevention science is contributing to a new generation of evidence-based approaches and policies that, if widely utilized, offer the potential of reducing the mortality and morbidity associated with a number of major health and social problems.     

The Relationship Between Adolescent Physical Abuse and Criminal Offending: Support for an Enduring and Generalized Cycle of Violence

Prospective investigations have demonstrated support for the cycle of violence theory. However, few studies have examined whether or not abuse occurring during adolescence increases the prevalence and frequency of criminal involvement, or explored the long-term consequences of such victimization. In addition, there has been little investigation of whether or not the effects of abuse vary depending on characteristics of the victim, such as sex, race/ethnicity, age, family structure or income. Using data from the National Youth Survey, this study demonstrates that adolescent physical abuse has immediate and enduring effects on the prevalence and frequency of a variety of self-reported offenses, including violent and non-violent crimes, drug use and intimate partner violence. Furthermore, the study reveals that while victimization increases the prevalence of offending for victims of varying backgrounds, the frequency of offending is moderated by family income, area of residence, and family structure. Implications for prevention are discussed.     

走私、贩卖、运输、制造毒品罪中“未经处理”之含义考探

走私、贩卖、运输、制造毒品罪中的"未经处理"只能解释为"未经刑事处罚",将非刑罚处置措施、行政责任或者其他法律责任视为对走私、贩卖、运输、制造毒品行为的处理方式是缺乏法律根据的。但是如此解释仍然存在一些问题,如使得刑罚过于严厉、影响刑法用语的统一性等,但是对于这些问题,非刑法解释所能为之,只能够通过刑事立法予以解决。     

物流毒品犯罪的侦控

物流毒品犯罪是随着我国物流行业的发展而产生的一种新兴的犯罪,由于物流毒品犯罪具有成本低、跨度大、渠道多、侦破难度大、容易逃避打击等特点,近年逐渐发展成为贩毒分子进行犯罪活动的重要方式,这一犯罪方式严重危害了我国的社会管理秩序。侦查机关只有加深对物流毒品犯罪特点的认识和了解,充分运用各种侦查措施和手段,才能提高对物流毒品犯罪的打击力度和精度。

Drug-facilitated sexual assault using tetrahydrozoline

Drug-facilitated sexual assault (DFSA) has been defined as the use of a chemical agent to facilitate a sexual assault. We report two cases of the use of tetrahydrozoline for DFSA. We believe this is the first report with urinary quantification of tetrahydrozoline levels postassault. Blood and urine were obtained c. 20 h postexposure in two cases of reported DFSA. Tetrahydrozoline was not detected in blood but was identified in urine in both victims. After initial identification in the urine using the 2010 update to the AAFS mass spectrometry database library, tetrahydrozoline was quantified at 114 and 150 ng/mL, respectively, using GC/MS. Two unique clinical features reported in these cases were intermittent periods of consciousness and postexposure vomiting. Use of GC/MS was successful in identifying tetrahydrozoline in the 100 ng/mL range up to 20 h postexposure. For victims with late presentation, urine may be a better sample for evaluation for tetrahydrozoline.
