[BBC Newsbeat] First ever festival to test users' drugs
People attending a UK festival have been able to test drugs on site for the "first time ever".
Campaigners say the practice known as "front of house testing" will help users know what they are taking.
Critics have always argued open testing encourages people to take illegal drugs.
But those in favour argue that people will always take drugs and this makes it safer.
Music fans at the Secret Garden Party in Cambridgeshire were able to try the scheme, run by the community interest company The Loop, at the weekend.
