An assessment of the potency related to Cannabis-based products in the South African market.

It was the aim of this study to analyse a portion of the South African cannabis-based products market and provide a detailed overview of their THC and CBD profiles. To date, no data of this kind exists in South Africa. Samples were submitted to a contract laboratory. A total of 840 samples were analysed in duplicate (1680 datapoints in total) and reported in an anonymous format. Samples were categorised into 7 different types: Edible, Extract, Infusion, Liquid, Other, Plant material, and Solid. Each category was divided into the following weight by percentage concentration levels:<0.1 wt.-%, 0.1 wt.-% to 1 wt.-% and finally>1 wt.-%. Both HPLC-UV, as well as, GC-MS was employed for analysis with the datasets combined. The results indicated that high amounts of THC are present in most of the cannabis-based products in South Africa. This is of concern due to the health implications of these products, and the current South African legislation related to CBD and THC. Medicines and controlled substance regulators as well as the South African public will be informed about the current state of cannabis-based products in South Africa.
