The Government Chemist team have published a report summarising
the findings of a ring trial to assess laboratories’ performance
in measuring CBD and controlled cannabinoids.
Background
The project has been funded by the Department for Business,
Energy & Industrial Strategy (BEIS), the Food Standards
Agency (FSA), the Home Office and the Office for Product Safety
& Standards (OPSS) and has been carried out in collaboration
with Food Standards Scotland (FSS) and the Defence Science and
Technology Laboratory (DSTL).
CBD and controlled
cannabinoids - Ring trial report

Cannabidiol (CBD) products have rapidly entered the UK market in
a variety of forms, including food and cosmetics. Laboratories
across the UK need to be able to accurately measure the CBD
content as well as the controlled cannabinoid content in
commercially available products. CBD and cannabinoids have been
highlighted as difficult compounds to analyse. The aim of the
ring trial was to share and compare methods for quantifying CBD
and controlled cannabinoids in food and cosmetics among testing
laboratories
Thirty-four national and international laboratories participated
in the ring. The results have shown that there is good agreement
of results between most laboratories. The data includes
instrument types and limits of detection which helped assess the
capability of testing laboratories and which will be invaluable
information to determine the UK capability in analysing CBD
products and controlled cannabinoids.
