Synthetic Cannabinoids (SC) are amongst the most prevalent class of novel psychoactive substances (NPS) which have emerged. The increase in hospitalisation and fatalities as a result of the prevalence of these SC and their abuse, highlights the necessity for the rapid and reliable screening for the substance within toxicological samples. Being able to rapidly screen for these substances would aim to improve overdose triage and ultimately improve treatment administration. Not only this but it would have further advantages for in-field applications such as the identification of drivers under the influence. To this avail we investigate the ability of a simple electrochemical screening strategy for the detection of SC, BB-22 and its primary metabolite BB-22-3-Carboxyindole. Assessment of the feasibility of the strategy for implementation into toxicological sample analysis was performed through detection not only under ideal electrolyte conditions (down to 5 µM for BB-22 and 2 µM for its metabolite) but also within the complex biological matrix of human pooled serum (between 200 and 700 µM), a relevant matrix it would likely encounter if employed within this field.
Designer drugs, also commonly known as new psychoactive substances (NPS), are increasingly in their prevalence and a challenge to toxicologists and forensic chemists. Synthetic cannabinoids (SCs) are among the largest group of NPS that have emerged in the illicit drug market all over the world. SCs may consist of different chemicals prepared in laboratories and herbal mixtures that said to be incense and not-for-human-consumption. The main aim of this paper is to investigate the use of electrochemical based methods for screening some of the emerging types of SC. More specifically, the paper takes electrochemistry approach called voltammetry to perform the detection and analysis of SCs whereby the main subjects for screening include STS-135 and 5F-ADB-PINACA. The expected result is that those compounds that belong to the same class should indicate almost similar behaviour to help achieve its objective, the paper reviews a number of recent publications relating to forensic drug analysis and much attention to electrochemical sensor methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
