The excretion in urine after single oral therapeutic doses of morphine derivatives was analysed with radioimmunoassay (RIA) and homogeneous enzyme immunoassay (EMIT) for opiates. In contrast to the rapid excretion of ethylmorphine and codeine, pholcodine showed positive results for opiates 2-6 weeks after intake when the urines were analysed with the RIA-method. When analysed with the EMIT-method, positive results were obtained for pholcodine for approximately 10 days. As pholcodine is a common component in cough mixtures, its prolonged excretion could represent a hazard in interpreting the results from drug analyses of urines. 相似文献

The analysis and findings reported here are from a self-report questionnaire survey of a sample of 1,035 high school students in Pusan, a metropolitan area of South Korea. Multiple regression and path analyses reveal that, for all types of drug behavior among these adolescents, the influence of parental variables was generally less than the influence of the peer variables. Even in South Korean society, where the stability and authority of the family is greater than in American society, peers have a greater influence than do parents on adolescents’ engaging in or refraining from deviant behavior. The findings conform more to the expectations of social learning theory than to those of social bonding theory, and generally replicate findings from research on adolescent drug use in the United States. Further research is clearly needed, but the findings here suggest that the social processes of substance use among adolescents and the theoretical explanations focusing on those processes are not confined to western societies.

An analysis is reported of 2,408 wiretap conversations gathered in the course of prosecuting a heroin dealing organization in New York City in the 1990s. The five-step analysis, which included a social network analysis of phone contacts, revealed a large, loosely structured group of 294 individuals, most of whom had very limited contacts with others in the group. The group’s active core comprised 38 individuals with extended contacts, little status differentiation and some task specialization. A smaller more tightly connected group of 22 individuals was somewhat independent of the remainder of the core and appeared to constitute a “communal business”. The existence was not confirmed of the large criminal conspiracy described by the prosecution that operated at all levels of trafficking and dealing, from wholesale distribution to street sales. Rather, it appeared that the 294 individuals comprised one segment of the heroin market in the city. However, the discrepancy could be due to the fact that the prosecution drew upon a wider set of information about the individuals concerned than provided by the wiretap data. The study supports recent analyses that see organized crimes, such as drug trafficking, as mostly the work of small groups of loosely linked entrepreneurs rather than large, highly structured criminal syndicates.

药物滥用是伴随着日本的社会环境的改变而发展变化的,近年来这种变化更为急速而多样.1997年日本迎来了药物滥用的最高峰,称为第三次滥用高峰期.对此,日本政府在1998年制定了"滥用防止五年战略"并加以推进,1998年至2002年五年间收到了一定的成效,但还未达到明显减少的程度.因此,又在2003年制定了"防止药物滥用新五年战略".相关的禁毒组织也采取了一定的对策. 相似文献

Cocaine is one of the most widely used illicit drugs worldwide. Cocaine powders seized by the Police may contain numerous other substances besides the drug itself. These can be impurities originating from the coca plant or the production process, or be purposely added to the drug formulation as adulterants and cutting agents. In forensic laboratories, identification of cocaine is routinely done through GC-MS analysis, but other components are often ignored even if the method allows for their detection. Yet, they can provide valuable insight into the history of a seizure and its potential connection to other samples. To explore this idea, an extensive review of common impurities and adulterants encountered in cocaine is presented. Based on their incidence, concentration in the end product and compatibility with GC-MS methods, their overall usefulness as candidates for the statistical investigation of existing forensic data is evaluated. The impurities cis- and trans-cinnamoylcocaine, tropacocaine, norcocaine and N-benzoylnormethylecgonine as well as the adulterants lidocaine, procaine, tetracaine, benzocaine, caffeine, acetylsalicylic acid, phenacetin, ibuprofen, levamisole, hydroxyzine and diltiazem are promising candidates to provide additional forensic intelligence. Future research on optimized routine GC-MS methods, signal reproducibility, comparison, statistics and databases is suggested to facilitate this concept. Ultimately, such an approach may significantly advance the amount of information that is extracted from routine casework data, elucidate developments in the cocaine markets in the past and facilitate Police work in the future. Preliminary assessment of existing data from the forensic laboratory of the Amsterdam Police has been included to show that the detection of the identified target impurities is feasible, and that small adjustments to the analysis method could significantly increase the detectability of these analytes in prospective drug screenings. Forensic intelligence based on retrospective data mining of cocaine containing casework samples may thus be realized with minimal additional laboratory efforts by using already available instrumentation, samples and data. 相似文献

风险规制法的目标和方法在于具体危险的防御和预防(可能的)风险。对于科技工艺和技术生产的物质或生物来说,除了惩罚禁止措施外,需要建构一套传统风险预防的前置制度,通过广泛的公众参与来对科技后果进行评估,从而采取相应的预防措施。风险规制的行政法方法包括传统的行政调控方式和信息规制方法、激励型规制手段等非禁令手段的方法。通过智慧的规制方法既可实现意欲达到的规制目标,同时也能降低行政管理成本和减少对经济活动的过度干预。 相似文献
