Samenvatting

Relatively new products which are mostly marketed by online communities and online influencers as healthy or having therapeutic effects are being sold across Europe and United States, online or local drugstores, without ensuring that these products go through any quality analysis. This introduces a threat on the consumer as there is no guarantee that the product does not contain toxic impurities. The aim of this research was to find simple methods to analyze CBD oil, e-liquids and CBD e-liquids for impurities and to determine the CBD concentration. E-liquids were analyzed for volatile components by the means of HS-GC/MS and ethanol was quantified by means of HS-GC-FID. For all the products containing CBD, the CBD and CBN was quantified by the means of HPLC-UV. CBD oil was analyzed for its chemical constituents by the means of GC/MS and Intuvo 9000 GC. Ethanol concentration in e-liquids was below trace levels (0.4 %) and from the possible identifications of volatile components, harmful compounds were not found. All CBD products had their CBD content within the optimal level (≤10 % difference to what is stated on the label). CBD oil contained also 0.3 mg/mL CBN. For the possible identifications of chemical constituents in CBD oil, no toxic compounds were found. Δ9-THC was found in the sample; however, the quantity is likely to be low and thus should not cause psychotropic effects to the consumer. The samples analyzed in this research do not contain toxic compounds and CBD products are within the optimal level. Regardless, it is highly recommended that regulations are set on these products and that it is certified that these products undergo quality analysis in order to ensure consumer safety.
