新型毒品2C-B的研究进展

2C-B是一种新型的毒品,它具有兴奋和致幻的双重精神作用。作为滥用品始于上世纪80年代的欧美地区,近年来,在一些亚洲国家和地区包括我国开始出现其滥用的情况,并有逐渐增多的趋势。本文就2C-B的合成方法、药毒理作用、代谢等方面进行综述。     

公安机关禁毒警队业务绩效基础示标体系初探

禁毒是公安机关的重要职能。禁毒警队作为公安机关禁毒工作的主要力量,其行为与禁毒工作的质量直接相关。而禁毒业务绩效基础示标的设立,对禁毒警察的行为选择有重要影响。通过对禁毒警队工作分析和业务绩效基础示标的初步探析,建立一套比较完整的禁毒警队业务绩效基础示标体系,以明确禁毒警队工作目标,促进其工作的积极性,对提高全国禁毒工作的绩效、不断完善公安机关的禁毒职能、为公众创造一个"无毒"的环境并最终提高公众对公安机关的满意度有重要意义。     

毒品致幻型犯罪可罚性探析

我国法律并未直接规定因食用毒品产生幻觉后犯罪的可罚性问题,司法实务界也存在很多的争议。基于对毒品致幻型犯罪行为人刑事责任能力的认定及"罪刑法定"原则适用可能性分析,最终认定毒品致幻型犯罪适用刑法,从而确定毒品致幻型犯罪的可罚性,为打击毒品犯罪,遏制毒品犯罪高发势头做出一定探索。

Comparison of bulk and compound-specific δ13C isotope ratio analyses for the discrimination between cannabis samples

Five marijuana samples were compared using bulk isotope analysis compound-specific isotope ratio analysis of the extracted cannabinoids. Owing to the age of our cannabis samples, four of the five samples were compared using the isotope ratios of cannabinol (CBN), a stable degradation product of Δ(9)-tetrahydrocannabinol (THC). Bulk δ(13)C isotope analysis discriminated between all five samples at the 95% confidence level. Compound-specific δ(13)C isotope analysis could not distinguish between one pair of the five samples at the 95% confidence level. All the measured cannabinoids showed significant depletion in (13)C relative to bulk isotope values; the isotope ratios for THC, CBN, and cannabidiol were on average 1.6‰, 1.7‰, and 2.2‰ more negative than the bulk values, respectively. A more detailed investigation needs to be conducted to assess the degree fractionation between the different cannabinoids, especially after aging.     

Driving under the influence of amphetamine-like drugs

Scientific opinions differ whether the use of stimulants causes deterioration in driving skills. In 1857 of 8709 cases of driving under the influence of drugs, amphetamine-like drugs (amphetamine, methamphetamine, and methylendioxyamphetamine) were present either alone or together with other licit or illicit drugs. In 338 cases, amphetamines were the only psychoactive substance group in plasma at mean, median, and highest concentrations of 0.18, 0.12, and 1.05 mg/L, respectively. A widespread opinion is that after the consumption of amphetamines, centrally stimulating effects with corresponding consequences on safe driving are expected. In contrast, many cases were observed that rather suggested an influence of centrally sedating substances when considering the psycho-physical conditions. Relations between concentration and effect could not be established. The apparent sedation is probably the consequence of sleep deprivation during an amphetamine binge and the after-effects of the drug.     

益气养阴药对糖尿病大鼠血糖及脂质过氧化作用的影响

目的:研究益气养阴药对糖尿病大鼠血糖含量及脂质过氧化作用的影响.方法:益气养阴药治疗糖尿病大鼠5周后,测定全血血糖水平,血清胰岛素活性,脂质过氧化物、丙二醛(MDA)水平,以及超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)活性.结果:与模型组比较,治疗组血糖和MDA水平降低,SOD和GSH-Px活性提高(P《0.05).结论:益气养阴药具有减轻糖尿病大鼠体内脂质过氧化反应、降低血糖的作用.     

窝藏 转移 隐瞒毒品罪质疑

窝藏、转移、隐瞒毒品、毒赃罪的犯罪对象毒品和毒赃是不同性质的两种物品,不宜规定在同一犯罪之中;窝藏、转移、隐瞒毒品罪的规定违背了赃物犯罪发生的时间和共同犯罪论,不宜规定为赃物犯罪。刑法关于窝藏、转移、隐满毒品犯罪的规定刑设置也不甚合理,应取消刑法第3 49条关于窝藏、转移、隐瞒毒品罪的规定,只保留窝藏、转移、隐瞒毒赃罪。     

GC双检测器技术筛选常见毒(药)物的可行性研究

利用气相色谱仪 ,在样品进样经单柱分离后通过Y形管连接至两个不同选择性检测器 (NPD/FID)的方法 ,考察气相色谱操作条件对双检测器响应比值的影响及其该法用于复杂样品测定的可行性。结果表明当实验条件保持不变时 ,NPD/FID响应比值具有较好的重现性。改变检测器操作参数和色谱条件对NPD/FID响应比值都有影响 ,但相对于某一参比物计算得到的相对NPD/FID响应比值受影响很小。样品中待测组份的浓度改变不影响NPD/FID响应比值。在有标准品比对的情况下 ,NPD/FID响应比值或相对NPD/FID响应比值可以作为定性分析的一个参数。     

Using National Incident-Based Reporting System Data for Strategic Crime Analysis

The utility of the National Incident-Based Reporting System (NIBRS) forstrategic crime analysis has yet to be explored. The NIBRS represents anadvancement over existing reporting systems and possesses considerableutility to frontline law enforcement with respect to strategic crimeanalysis. This paper discusses the utility of the NIBRS for identifyinglocal and regional trends in narcotics related offenses. As an example, weselected four localities from the 1997 Virginia NIBRS data to examine trendsin the sale/distribution and possession of narcotics. Our analysis showsthat the NIBRS provides significantly more incident-related detail than hasheretofore been available for strategic crime analysis at the regional orstate level. Moreover, the NIBRS provides neighboring communities theopportunity to compare information on emerging crime patterns and criminalenterprises which extend beyond local boundaries. Finally, enhancing localreporting compliance by highlighting the strategic utility of the data tolocal law enforcement will ultimately ensure the quality of the data set,which can then be employed by larger entities as well as criminal justiceresearchers for policy development and planning.
