Pill testing advocates will break the law and offer punters the service at either Groovin the Moo or Spilt Milk in Canberra this coming festival season.

Will Tregoning, the founder of harm reduction agency Unharm, is one of the three drug policy experts who earlier this year said they would offer festival pill testing, and potentially get arrested, in order to test the reaction of authorities.

It came after six drug-related deaths at music festivals in 2015.

Pill testing is a service where punters can go to have illegal drugs such as MDMA tested for purity and the presence of dangerous additives like ketamine.

It's one of the only ways of knowing what you're taking, and if you bought what you paid for.

The other drug experts who have been working with Will Tregoning are Australian Drug Law Reform Foundation president Alex Wodak and Canberra physician David Caldicott.

It's not clear if the three are still working together.

Earlier this year, they said they would do testing at Sydney festivals, and then in April they revealed they were looking at jurisdictions outside of NSW.

Today, Tregoning told Hack it would happen in the ACT.

"I think we will see drug checking or pill testing in Australia this year," he said.

"It won't happen in NSW. It's much more likely to happen in the ACT."

Asked if he meant Spilt Milk (held in Canberra in December), he said he could also be referring to Groovin the Moo (also Canberra, to be held early next year).

"Canberra doesn't have the biggest festival but there's an opportunity to prove this is a viable and effective thing that can really work," he said.

"All these things that people come up with about how we can't possibly do this in Australia - they can easily be disproved by showing this can be done.

"Pill testing is being used in at least 10 countries around the world.

"Absolutely we know it's working."

We don't endorse pill testing: ACT Government

NSW Police and the Baird Government had labelled the project illegal and Tregoning described the atmosphere in NSW as "very negative and tense".

Hack asked the ACT Government if it was considering allowing pill testing inside festivals. A spokesperson said it was "not a government endorsed approach".

It noted there was no law prohibiting the possession of drug-testing kits, but that possession of illegal drugs remained an offence.

"The ACT Government is committed to its harm-minimisation approach to illicit drugs, and is constantly looking at ways to better reduce harm, reduce supply and reduce demand."

The news comes the day after the ACT Greens pledged their support for the idea of pill testing at Canberra music festivals. They said they would take it to the Legislative Assembly after the October election. Labor and the Liberals staunchly oppose the idea.

According to Hack's massive annual survey, a majority of our young listeners support pill testing.

Of the people surveyed who said they used drugs (about half), about 80 percent said they would use pill testing at a festival.

According to this year's world drug survey, there's never been more MDMA available globally, and the quality is getting better. This increases the risk of overdose, leading some to say it is "the worst time to start taking MDMA in a generation".
