Herbal smoking blends, available on the German market were analyzed and several known synthetic cannabinoids were identified (JWH-122 and JWH-018). In addition, we isolated a new active ingredient by silica gel column chromatography and elucidated the structure by nuclear magnetic resonance (NMR) methods. The compound was identified as JWH-307, a synthetic cannabinoid of the phenyl-pyrrole subclass with known in vitro binding affinities for cannabinoid receptors. To date, this is the first appearance of this subclass of cannabimimetics in such products. JWH-307 has been further characterized by gas chromatography accurate mass spectrometry (GC-HRMS), electrospray tandem mass spectrometry (ESI-MS/MS), ultraviolet (UV) and infrared (IR) spectroscopy. JWH-018 was among the first compounds banned by many countries world-wide including Germany. The identification of JWH-018 was striking, since this is the first report where JWH-018 recurred on the German market thus violating existing laws. A generic method was established to quantify synthetic cannabinoids in herbal smoking blends. Quantification was achieved using an isotopically labeled standard (JWH-018-D(3)). JWH-018 was found at a level of 150mg/g while JWH-122 and JWH-307 occurred as a mixture at a total level of 232mg/g. 相似文献

The ‘six‐pack,’ a set of six Union legislative acts that was adopted in November 2011, was one of the main Union responses to the current sovereign debt crisis. Aware of the weak performance of the Stability and Growth Pact and of the underlying design faults of the Treaty provisions on the coordination of Member States' economic policies, in particular the multilateral surveillance procedure (Art 121 TFEU) and the excessive deficit procedure (Article 126 TFEU), the legislators were determined to strengthen the means of surveillance in this policy field. One step considered necessary to achieve this end was the introduction of reverse majority voting in the Council when the latter has to adopt, for example, sanctions in above procedures. This article will examine whether this voting method is compatible with the Treaties. 相似文献

Road safety plays an increasing role in communities throughout the entire world. According to estimates, road accidents will have moved from ninth to third in the worldwide ranking of burden of disease by 2020. This theme issue is dedicated to community-based applications that have the aim to enhance road safety. Although various interventions will be demonstrated, this issue provides by no means an exhaustive overview of community-based applications. The applications presented in this issue are predominantly meant to stimulate ideas and discussion on what can be done to enhance road safety. 相似文献

The isotope ratios of amphetamine type stimulants (ATS) depend as well on the precursor as the synthetic pathway. For clandestine production of amphetamine and methamphetamine, 1-phenyl-2-propanone (P2P, benzylmethylketone) is a commonly used precursor.Our aim was to determine the variation of the isotope ratios within precursor samples of one manufacturer and to compare seized samples of unknown sources to these values. δ13CV-PDB, δ2HV-SMOW and δ18OV-SMOW isotope ratios were determined using elemental analysis (EA) and gas chromatography (GC) coupled to an isotope ratio mass spectrometer (IRMS). The comparison of all seized samples to the data of the samples of one manufacturer revealed considerable differences. The results show that IRMS provides a high potential in differentiating between precursors from different manufacturers for the clandestine production of ATS and identifying corresponding sources. 相似文献
