Aim:Products containing cannabidiol (CBD) are currently very popular. They are consumed for various purposes, and can have a beneficial effect on some health conditions. The aim of this work was to investigate the composition of commercially available CBD products in the form of oils and pastes as well as two available HHC oils. The aim of this work was to determine the concentration and proportion of the following cannabinoids: CBD, CBDA, CBN, THC and HHC. By comparing the percentage of cannabinoids determined with the cannabioids listed in the product declaration, we were able to gain an insight into accuracy of the accompanying declarations. Methods: CBD products (20 oils and 11 pastes) and two HHC oils were purchased in local specialized CBD stores or online stores in Croatia and Slovenia. CBD, CBDA, CBN, THC and HHC concentrations were quantified in CBD oils and pastes, and HHC oils using high performance liquid chromatography with a UV/VIS detector (HPLC-UV/VIS). Note that the concentration of HHC is expressed above the THC concentracion as we did not have an HHC standard available. Results: CBDA was detected in more than half of the CBD oils (64%) and (80%) of the CBD pastes tested, while CBN was only present in traces in less than 10% of the oil samples and 36% of the paste samples. The analysis revealed a large deviation of the CBD content in CBD oils from the information on the accompanying product declaration. In almost all of the CBD oil samples tested, the CBD content was less than half of that stated on the declaration. In the case of CBD pastes, the analysis carried out confirmed that the CBD content was correctly declared in almost 30% of the samples, whereby the CBD content is one sample was 7% higher than stated on the declaration. Other paste samples contained a CBD content that was around 50% lower. In the CBD oil and pastes tested, as well as in the HHC oils, we were unable to detect THC in higher proportion than the permited 0,2%. The analysis of HHC oil showed that the čproportion of the active ingredient in these products is also lower than stated in the declaration. Conclusions: The data presented show that the majority of industrial hemp oils and pastes available on the market are mislabeled and therefore pose a potential risk to human health. The results of this investigation clearly show that these products need to be analyzed more frequently by accredited laboratories in order to protect consumers and gain a more accurate insight into the market situation of these increasingly popular dietary supplements.
