Lyndon Edney, who said he did not condone drug use, said the safety of young people should be the top priority.

He said it was naive to think that young people would not be exposed to drugs, but said they should have the option to make an informed decision about what they are putting in their bodies.

Mr Edney said he had a frank conversation with his daughter Kailyn, 18, after she attended a music festival where someone died from a drug overdose.

"We have open talks about that sort of stuff at home," he said.

"It's not something that we brush under the carpet like a lot of families do."

Mr Edney said he believed pill testing would prevent deaths and was surprised people didn't support it for that reason.

"Whether they want to party or not, the protection should be there," he said.

"It doesn't have to be only testing - there should be somewhere they can go to and talk to educated staff to know what they're taking."

Mr Edney's comments come after The Greens revealed they are pushing for a pill testing trial in Victoria to combat overdose deaths at music festivals.

Under the proposed laws, a 24 month trial could begin as early as 2020, with scope to be extended for another four years.

The bill, first flagged in February, is named in memory of 34-year-old Daniel Buccianti, who died at the Rainbow Serpent music festival after taking LSD in 2012.

It would create a mobile facility to test drugs at festivals, with amnesty bins available for party goers to ditch the substances.

"We know that most people choose to throw out their drugs when informed that they contain harmful substances," the Green's drug law reform spokesman Tim Read said.

A fixed laboratory would also be created for year-round testing.

Mr Buccianti's mother, Adriana, supports the proposal and says no parent should have to go through what she has.

"But in the last 12 months, at least five other families have lost their child from drug overdoses," she said.

The Labor Andrews government is opposed to pill testing.

Canberra's Groovin the Moo festival was Australia's first to allow pill testing in 2018.

A second trial also ran earlier this year.
