@neversickanymore the CANTest service is not a research project, it's actually a drug checking service - the first fixed site service to operate in Australia. Unfortunately only for people in Canberra, but will accept anyone who turns up, even if their address is not local. So it's an option for this person, but a large expense to get there....
There's also the international Energy Control service, that takes a while though (a few weeks) as you need to post the drugs to Spain... but it's super reliable.
As for other options, there may be some but they are not 'public'. I will ask around.
