I have not personally done any work on this subject, we have a VMD license and have to do an awful lot of mandatory research on all the product we stock that have licenses, we have learnt a lot from the NOD fiasco, changing containers and the new product that is soon to arrive around 3 years late. It unlikely that Certan will come back to the UK market anytime soon, the market in the UK is too small. The cascade system is in taters at the moment with no one really knowing what is allowed and what isn’t.
