Health Minister Steven Miles would not say whether he would take up Dr Caldicott's invitation to conduct a similar trial in Queensland.
He said the government would instead be"looking closely at the work currently underway in Canberra in relation to the use of pill testing as a harm reduction strategy".

The ACT conducted two pill testing trials at Groovin the Moo festivals in Canberra in April 2018 and April 2019.
A report into the 2018 trial found more than 80 per cent of participants believed they were taking MDMA,also known as ecstasy,when in reality less than half of all samples contained relatively pure MDMA.
Substances linked to a mass overdose overseas were also found in the tablets tested.
The results from the second trial are expected to be shared with all health ministers at the nextCouncil of Australian Governments meeting,most likely in November.
