The nation's first illicit pill-testing trial at Canberra's Groovin the Moo festival has been deemed a success by drug treatment experts.
In a controversial move, partygoers were able to get their drugs tested by volunteer medical staff and chemical analysts at Sunday's event.
The STA-Safe consortium received the last-minute go-ahead to offer free pill-testing in a mobile laboratory in a festival health tent, with the support of the ACT government and ACT Police.
Nearly 130 participants took advantage of the service with the medical service testing 85 samples, according to the Ted Noffs Foundation
"We've just taken a big step towards taking back control of the dangerous black market in drugs in order to keep our kids safe," chief executive Matt Noffs said in a statement on Monday.
