Comprehensive Protocol for the Identification and Characterization of New Psychoactive Substances in the Service of Law Enforcement Agencies.

ABSTRACT: A non-routine, comprehensive protocol for characterization of emerging new psychoactive substances (NPS) including chemical structures, impurities, as well as crystal structures, has been developed to facilitate the work of law enforcement agencies. A set of NPS has been synthesized, identified, and characterized by various analytical methods in order to be used as certified reference standards (CRMs). Seven selected compounds (5-IT, NM-2201, MT-45, AB-CHMINACA, UR-144, 5F-PB-22, and 4-CMC) were synthesized on the laboratory scale, then the process was upscaled to semi-technical. All products were analyzed by electrospray Q/TOF-MS/MS for molecular structure identification. The presence of by-products, as well as metal impurities, arising from the performed syntheses, were characterized by reversed phase liquid chromatography (RP-HPLC) with DAD and Q/TOF-MS detection and inductively-coupled plasma with quadrupole mass spectrometer (ICP-QMS), respectively. Additionally, the crystal structures of UR-144, NM-2201, 5F-PB-22, and 4-CMC have been determined by single-crystal and powder X-ray diffraction.

Project description:IntroductionIn recent years, tobacco control policy initiatives have emerged at the subnational level in China. In 2013, for example, Qingdao enacted a 100% smoke-free policy that gave regulatory authority to multiple enforcement agencies. Given that little is known about the extent of smoke-free policy compliance in smaller Chinese cities, this study assessed compliance with Qingdao's Tobacco Control Regulation and whether compliance differed by enforcement agency.MethodsA cross-sectional observational study was undertaken between October and November 2018. Venues were selected based on enforcement agency and included restaurants, retail stores, schools, government buildings, hospitals, business offices, and other hospitality venues. Comprehensive lists of venues were identified where they existed, and a random sample of venues were subsequently selected. For venue categories for which there were no comprehensive lists, a walking protocol was used. Observational data included evidence of smoking, the presence of no-smoking signage, and designated smoking areas (DSAs). Descriptive statistics were obtained. Subsequently, logistic regression models were used to determine the association between enforcement agency and policy compliance.ResultsA total of 694 venues were observed. For all venue types, 64.7% were compliant with the composite indicator 'evidence of smoking'. Findings also showed that smoke-free compliance varied by enforcement agency (p<0.001). Venues with evidence of smoking and not posting of no-smoking signs at the main entrance were lowest among venues that fall under Public Security Bureau. Compliance with posting no-smoking signs inside was lowest in venues that fall under the Industry and Commercial Administration (I&C). While Qingdao's smoke-free policy prohibits DSAs, our findings showed that 2% of venues that fall under the jurisdiction of I&C had DSAs.ConclusionsAn effective coordination mechanism that can ensure a consistent and standardized approach is urgently needed in Qingdao. With such a concerted effort, it will be possible to achieve the target of 100% smoke-free indoor places in Qingdao.
