Abstract

In 2008, several synthetic cannabinoids were detected in herbal smoking blends sold on websites and in the so-called “smart shops”. These compounds, as well as new psychoactive substances, flooded the market of illicit drugs and are sold at street level. Development and validation of rapid analytical methods for the detection and quantification of synthetic cannabinoids in biological matrices are essential for the investigation of pharmacokinetic, pharmacodynamic and toxicological properties. In this pilot study, the potential of direct immersion solid-phase microextraction coupledto GC/MS for the determination of synthetic and natural cannabinoids in oral fluid was proved. Validation proved the suitability of the developed method for the determination of the analytes at trace levels in oral fluid: linearity was assessed in the LOQ – 1000 ng/mL range, whereas a good precision was observed with CV below 20%. The method was then applied to more than 100 real oral fluid samples collected from a population of young students, showing a positivity rate of 3.8%
