9-Tetrahydrocannabinol (THC) is known as the main psychotropic compound present in the hemp plant. It also occurs in commercially available hemp food products and may have adverse effects on consumers. This article provides an overview of the current situation of the THC content in hemp food products in Germany in recent years. The content of THC w...
Toxicologically relevant levels of the psychoactive ∆9-tetrahydocannabinol (∆9-THC) as well as high levels of non-psychoactive cannabinoids potentially occur in CBD (cannabidiol) oils. For consumer protection in the fast-growing CBD oil market, facile and rapid quantitative methods to determine the cannabinoid content are crucial. However, the curr...

Cannabidiol (CBD) is a naturally occurring, non-psychotropic cannabinoid of the hemp plant Cannabis sativa L. and has been known to induce several physiological and pharmacological effects. While CBD is approved as a medicinal product subject to prescription, it is also widely sold over the counter (OTC) in the form of food supplements, cosmetics a...

... Therefore, CBD products intended to be marketed as food or food supplements in the EU require prior authorisation. Despite being widely advertised and sold in increasing quantities, all CBD oils and CBD-containing food supplements available in the EU are currently marketed in violation of food laws [4]. This is no longer a niche, as the total 2020 EU CBD market has been estimated at EUR 1.6 billion [5]. ...

... For an intuitive comparison, the relative contents of other cannabinoids are then given in percent relative to the main cannabinoid. As the CH 2 -1″ signal of the pentyl side chain of cannabinoid acids is typically found in the region between δ H 2.75 and 2.90 ppm without the interference from other cannabinoids [25,26], this region was integrated and compared to the sum of THC, CBD, and CBG identified in the sample. This allowed to estimate the amount of cannabinoid acids left in the extract after decarboxylation. ...

... Acids can be used to catalyze the reaction converting CBD into psychotropic transformed substances, such as D 9 -THC, D 8 -THC, and hexahydrocannabinols (HHCs) [6]. Other than these major transformed products, hydroxy-CBD derivatives and hydroxy-HHC derivatives are observed under acid treatment of CBD [3,4]. Most of these transformed products are psychotropic substances. ...
