"I think that would be a natural conclusion to draw. I know there's been a lot of discussion with governments,but most governments outside the ACT have taken a position against it,but now they have an understanding of how it operates,"he said.
"What they should do is reopen political discussion on pill testing,now there's Australian-based evidence."
There were 128 participants in last weekend's trial. Eighty-five samples were tested by the STA-Safe Consortium, two of which were deadly.
Substances linked to a mass overdose overseas were also found in the tablets tested,while some samples also contained ingredients such as lactose,paint or condensed milk.
Mr Vumbaca said he hoped other governments would be open to the idea of pill testing in their jurisdictions following the successful trial.
