Canberra's Groovin the Moo festival held the nation's first illegal pill-testing trial over the weekend.

Out of the 128 participants, 85 samples were tested. Half of them were pure MDMA while the other half included, lactose, sweetener and paint. Despite this, 2 samples were found deadly.

Chief Executive of the Ted Noffs Foundation, Matt Noffs, says this is a big step in taking back control and making our kids safer.
