The Director of Public Prosecutions (DPP) will consider whether charges should be laid over the death of a man who took kambo frog poison at a festival in northern NSW.

Jarrad Antonovich, 46, died from a perforated oesophagus at the Dreaming Arts Festival near Kyogle in October, 2021.

A coronial inquest has previously heard he used kambo and the psychedelic substance ayahuasca while at the festival, which was organised by Lore Solaris.

Mr Solaris was scheduled to give evidence at the inquest today, but NSW State Coroner Teresa O'Sullivan adjourned the case and referred the matter to the DPP.

What is kambo?

Kambo, the dried skin secretions of the Amazonian giant leaf frog, was classed as a prohibited substance in Australia in October 2021, about two weeks prior to Mr Antonovich's death.

At that time the Therapeutic Goods Administration classified it as a substance of "such danger to health as to warrant prohibition on sale, supply and use".

Kambo devotees make small dot-like burns on their skin before applying the poison, which induces severe vomiting.

The process is claimed to rid the body of toxins, but Australian health authorities say there is no evidence to support that claim and that kambo carries the risk of heart attack and damage to the liver and stomach.

Ayahuasca, a plant-based psychedelic drug traditionally used by Indigenous South American shamans, was banned in 2022.

The plant grows only in the Amazon and, when brewed with other natural jungle products, becomes one of the most powerful hallucinogens in the world.

Unable to stand

The inquest previously heard that on the day of his death Mr Antonovich participated in the kambo ceremony at about 10am, during which a number of "points" of the poison were applied to burn marks on his skin.

By about 5pm Mr Antonovich needed support to stand.

He died that evening on a mattress at the back of the venue while an ayahuasca ceremony was being held.

A number of people told the inquest they thought Mr Antonovich needed professional medical care, but they did not act as they felt they should defer to event organisers, including Mr Solaris.

State Coroner Teresa O'Sullivan previously told the court she hoped the inquest would highlight the importance of seeking professional medical assistance.

"Paramedics are not there to prosecute people," she said.

"They are there to save lives.
