Effects of external influences on synthetic cannabinoid trends in New Zealand, 2014 to 2020.

Over the past decade, synthetic cannabinoids have inundated the global market and now form the largest category of new psychoactive substances. Once these chemicals are available on the global market, they can be applied to plant material in a clandestine environment to create an end-product that is smoked by the user. The synthetic cannabinoids AMB-FUBINACA and 5F-ADB were most frequently detected between 2017 and the beginning of 2019. More recently, these two appear to have been replaced by different synthetic cannabinoids. This investigation summarises the recent trends in synthetic cannabinoids detected in New Zealand between 2017 and 2020 and outlines the potential factors influencing these trends.

The phenomenon of para-Fluorophenylpiperazine (pFPP) in combination with the synthetic cannabinoid AMB-FUBINACA in seized plant material in New Zealand.

New psychoactive substances have emerged as a vast and diverse group of illicit drugs over the past decade, with synthetic cannabinoids comprising the largest of the categories. Commonly, a single synthetic cannabinoid is applied to plant material, creating a product that is designed to be smoked by the user. The clandestine preparation process can result in an unevenly distributed product, with varying concentration within and between plant materials. This investigation describes the novel co-detection of the synthetic cannabinoid AMB-FUBINACA, with the piperazine para-fluorophenylpiperazine (pFPP), in a number of plant material samples analysed in New Zealand in 2017. Of 157 samples of plant material containing AMB-FUBINACA, pFPP was detected in 55 of them. A range of pFPP concentrations was observed between the plant material samples, as well as intra-batch variation. The presence of both drugs may be designed to enhance, prolong or balance the psychoactive effects caused from smoking the plant material. However the intended purpose has not been verified. This is the first reported combination of a synthetic cannabinoid and a piperazine in plant material.

The identification and quantification of synthetic cannabinoids seized in New Zealand in 2017.

There has been an explosion of new psychoactive substances (NPS) over the past decade, with synthetic cannabinoids comprising one of the more extensive and chemically diverse groups. Synthetic cannabinoids, like other NPS, are continually evolving with slight alterations in chemical structure, which can lead to unintended and harmful effects for the user. Furthermore, the clandestine preparation of plant material containing one or more synthetic cannabinoid can result in an unevenly distributed product, which poses an additional risk to the user of increased doses. This investigation aimed at providing a snapshot of synthetic cannabinoids in New Zealand in 2017, including the concentrations of synthetic cannabinoids in plant material. Overall, ten different synthetic cannabinoids were detected, with AMB-FUBINACA and 5F-ADB comprising the majority of samples analysed. The synthetic cannabinoid AMB-FUBINACA displayed the greatest range of concentration in plant material, from 5 to over 400 g of synthetic cannabinoid per kilogram of plant material. There was also geographical variation in the synthetic cannabinoids depending on where in New Zealand they were seized from.
