SP - e110469 EP - e110469 VL - 316 IS - N2 - Reports have shown the prevalence of the contamination of banknotes with a number of different drugs. These studies have focused on investigating drug contamination levels on currency which is either nationally or even international distributed. To present there has been no studies undertaken on banknotes circulating in well-defined and limited geographic areas. In this present study we have investigated the presence of drug contamination on the Local Currency, circulating in a known geographic area in and around the city of Bristol, UK; the Bristol Pound (£B). The effect of sample size was investigated and a post-hoc statistical power analysis undertaken. Following liquid extraction with the aid of sonication, levels of cocaine, benzoylecgonine, MDMA, ketamine and methamphetamine were determined by liquid chromatography triple quadrupole mass spectrometry. Seven samples of each denomination in circulation were investigated. The calculated median values per note were 2030ng cocaine, 91.9ng benzoylecgonine, 0.779ng methamphetamine, 62.8ng MDMA and 3440ng ketamine. This study focuses on our preliminary studies and to our knowledge this is the first investigation focused on the drug contamination of a Local Currency.
