CBD is an emerging constituents of many different products type. But how much do we know about it? What are the elements helping us to evaluate the quality<\/strong> of the products bloomed on the market? TRUSTiCERT funded a first project focused on CBD e-liquids<\/strong> and CBD oils<\/strong>;\u00a0 the aim of this work is dual: on one side, to investigate the real content of cannabidiol<\/strong> in liquids; on the other, to verify the effects of different storage conditions<\/strong> on the CBD amount.<\/p>\n

<\/p>\n

The accuracy in labelling<\/p>\n

<\/h3><\/div>\n

The accuracy in labelling is an issue well known also by the FDA. TRUSTiCERT analyzed the actual CBD contents of 13 commercially available e-liquids: only 38%<\/strong> of samples were correctly labelled<\/strong> (considering a tolerance of +\/- 10%). 4 samples out of 13 had a experimental CBD concentration 90% lower than the declared one. This warning picture might be explained either by low manufacturing practices used by companies or by degradation of the phytocannabinoid as a result of wrong storage conditions.<\/p>\n

<\/p>\n

The chemical stability<\/p>\n

<\/h3><\/div>\n

The chemical stability<\/strong> upon storage and shipping of CBD e-liquids instead is an issue never previously assessed: these lacking data are extremely important considering the chemical stability of CBD that undergoes degradation when exposed to light and temperature. To investigated the effect of temperature<\/strong>, we carried out stability testing upon storage at 4\u00b0C, Room Temperature (RT) and 37\u00b0C for 30 days. The effect of light<\/strong> on CBD products was also investigated by storing the solutions for 30 days at RT placing alongside two identical samples, one wrapped in aluminium foil, and one under a natural day light exposure.<\/p>\n

<\/p>\n

Results<\/p>\n

<\/h3><\/div>\n

Storing samples at 37\u00b0C turned out to promote the degradation of CBD: all the samples showed a decrease in CBD concentration above 10%, 4 of which above 15% across one month storage. Otherwise, storing e-liquids at 4\u00b0C<\/strong> allows a minimal to none degradation<\/strong> of CBD preserving the quality of these products. Also light exposition showed a net detrimental effect, with an overall loss in CBD concentration equal or greater than 10%. Instead, when the e-liquids were stored in absence of light<\/strong>, the CBD concentration<\/strong> was stable<\/strong>.<\/p>\n

In conclusion, in order to minimize detrimental effects on CBD content<\/strong>, we recommend manufacturers to use light-protective containers<\/strong>, to set up a good quality control facility and to provide the customers with clear indications<\/strong> about the best practice for the storage conditions<\/strong>.<\/p>\n<\/div>
