利用现代物证分析技术推断毒品的来源

利用现代物证分析技术推断毒品的来源,是侦查毒品案件的客观要求,对打击毒品犯罪具有重大意义。随着气相色谱同 位素比值质谱、电感耦合等离子体质谱等现代分析技术的出现,使得我们利用现代物证分析技术推断毒品来源成为可能。     

论吸毒者持有毒品行为之定性与定量

吸毒者涉毒案件在毒品犯罪中占有较大比重,其定性与处罚为司法实践所重点关注,其间,既涉及罪与非罪之界定,也涉及此罪与彼罪之区分,当具体分析认定:吸毒者为了自己吸食、注射而非法持有较大数量毒品的,应以非法持有毒品罪论处;对以贩养吸者持有毒品的,应根据其持有毒品的目的、数量,结合证据使用规则,分别以贩卖毒品罪、非法持有毒品罪或者非罪定性处理;对吸毒者已经吸食、注射之毒品不得再计入非法持有毒品的数量之中。

警务人员在禁毒执法中的新挑战

随着禁毒形势的日益严峻及艾滋病迅速蔓延对公众社会造成的威胁和危害,减低毒品危害系列政策应运而生,警务人员在执法工作中的新困难也随之产生。一是执行减低毒品危害措施存在着法律障碍,导致执法警察有可能对一些违反禁毒法律法规的行为抱“忽视”态度;二是随着减低危害工作加入警察执法内容中,警察工作将会比以前更辛苦、艰难;三是禁毒工作还得寻找新的有效措施与其他部门合作。     

Medical Practice in Early Colonial Spanish America: A Prospectus

This paper outlines the current state of research on medical practice in early colonial Spanish America. It argues that medical practice in Spain was more diverse than generally supposed, and that this complicated the exchange that occurred between Native American, African and European medical traditions in the Americas. Control of medical practice in Spanish America was exercised not through the establishment of state institutions, but through the close working of the state and the Church that on the one hand promoted medical care as a charitable activity and on the other sought to suppress practices that were incompatible with Catholic beliefs. However, due to the shortage of trained medical practitioners, the authorities were relatively tolerant of alternative medical practices and this enabled a process of exchange and fusion. The paper illustrates these processes with respect to medical practice in Cartagena de Indias in the early seventeenth century. It concludes with suggestions of avenues for future research.     

RACE,DRUGS, AND POLICING: UNDERSTANDING DISPARITIES IN DRUG DELIVERY ARRESTS*

This article draws on several unique data sources to assess and explain racial disparity in Seattle's drug delivery arrests. Evidence regarding the racial and ethnic composition of those who deliver any of five serious drugs in that city is compared with the racial and ethnic composition of those arrested for this offense. Our findings indicate that blacks are significantly overrepresented among Seattle's drug delivery arrestees. Several organizational practices explain racial disparity in these arrests: law enforcement's focus on crack offenders, the priority placed on outdoor drug venues, and the geographic concentration of police resources in racially heterogeneous areas. The available evidence further indicates that these practices are not determined by race‐neutral factors such as crime rates or community complaints. Our findings thus indicate that race shapes perceptions of who and what constitutes Seattle's drug problem, as well as the organizational response to that problem.     

福建省娱乐场所涉毒问题现状及治理对策

自20世纪90年代末新型毒品进入福建省娱乐场所后,在七八年的时间里,这些场所内滥用的毒品从最初的摇头丸发展为现在的多种类、混合型毒品并存,消费人群也在成倍增长,由此产生的社会危害性日益突出。福建省各地禁毒执法部门针对本地娱乐场所的涉毒情况陆续开展了整治工作,但一些工作上的难点直接制约了治理成效,因而有必要探讨加强娱乐场所涉毒问题的治理对策。     

试论毒品来源同一认定的理论基础

毒品来源同一认定是我国当前毒品检验工作中一个亟待解决的重大课题。从物证理化检验中种属认定的哲学基础上,可表明特征反映体的发掘和表达与种属认定范围之间的正相关关系,以及毒品海洛因的杂质和稀释物在新一鉴定层次中的作用。只要正确认识事物发展、变化的客观规律,充分发挥现代科学技术的作用,就一定能不断拓展我们的视野,把毒品检验的种属认定引向深入,以达到不同层次的“同一”。

GC–MS studies on acylated derivatives of 3-methoxy-4-methyl- and 4-methoxy-3-methyl-phenethylamines: Regioisomers related to 3,4-MDMA

A series of side chain regioisomers of 3-methoxy-4-methyl- and 4-methoxy-4-methyl-phenethylamines have mass spectra essentially equivalent to the controlled drug substance 3,4-methylenedioxymethamphetamine (3,4-MDMA), all have molecular weight of 193 and major fragment ions in their electron ionization mass spectra at m/z 58 and 135/136. The acetyl, propionyl and trifluoroacetyl derivatives of the primary and secondary regioisomeric amines were prepared and evaluated in GC–MS studies. The mass spectra for these derivatives were significantly individualized and the resulting unique fragment ions allowed for specific side chain identification. The trifluoroacetyl derivatives provided more fragment ions for molecular individualization among these regioisomeric substances. These trifluoroacetyl derivatives showed excellent resolution on a non-polar stationary phase such as Rtx-1.
