Cannabidiol and tetrahydrocannabinol concentrations in commercially available CBD E-liquids in Switzerland.

Introduction:
This article presents the results of a study that analyzed the CBD and ThC content of 20 commercially available CBD e-liquids in Switzerland. The study also aimed to identify any potential adulterations with synthetic cannabinoids.

Key Points:

* The study found that all e-liquids met the required Swiss legal regulations of a ThC content lower than 1% and had contents lower than 0.2% (w/w), which is the maximal allowed ThC concentration in the European Union.
* however, manufacturer information on the label and packaging varied drastically from the determined CBD content in a range of 45.9% –117.9%.
* The two e-liquids without specification of the CBD content contained the lowest total CBD concentration (0.182 and 0.348% (w/w)).
* The study did not find any synthetic cannabinoids in the e-liquids.
* The authors suggest that the discrepancies observed for the determined and labelled CBD content may be due to a lack of regulations and quality specifications for CBD-containing products in Switzerland.
* The study highlights the need for accurate and reliable labelling of CBD products to ensure consumer safety and trust.

Main Message:
The study found that the CBD content of e-liquids available on the Swiss market varies in quality, and consumers cannot rely on the manufacturer's information. The lack of regulations and quality specifications for CBD-containing products in Switzerland may contribute to the observed discrepancies in CBD content. The study emphasizes the importance of accurate and reliable labelling of CBD products to ensure consumer safety and trust.
