Recreational drug users would be able to pop in to a shop and test their pills under a plan by the Australian Greens.
Party leader Richard Di Natale on Friday paid a morning visit to a Melbourne nightclub to unveil plans for 18 pill-testing shopfronts, costing $16 million over four years.
Six of the proposed shops would be in major cities and 12 in rural areas, with mobile facilities available for music festivals and special events.
Pills would be tested for purity and dangerous substances, saving young people's lives, Dr Di Natale said.
"It's a policy that, if implemented, means that young people won't die - it's as simple as that," he said.
"It doesn't matter what politicians say, it doesn't matter what police officers might say, people will continue to make these choices and the question we face is ... should they be safe? Should they be forced to pay with their life?"
Di Natale said the successful trial at Canberra's Groovin The Moo music festival in April proved pill testing also worked as a deterrent.
"The evidence there was crystal clear - people had their drugs tested and when they were found to be contaminated with dangerous substances, they turfed them out."
The service could also identify and warn people against buying lethal batches of drugs on the street, rather than relying on the word of their drug dealer.
He said similar services overseas had led to pills with less dangerous ingredients.
The shopfronts would be staffed 10 hours a day, four days a week.
The Victoria Greens also announced plans for a separate $3.5 million two-year state trial, including mobile services for festivals as well as fixed locations.
The proposal's similar to the Reason Party's policy to install front-of-house drug checking facilities at music festivals and other events.
Greens health spokeswoman Nina Springle admitted the two party's platforms have "synergies".
"It's a multitude of voices that's required for systemic change," she said.
The Reason Party will host a five-hour rave on Friday night at an inner-Melbourne bar to gather support for its pill testing policy.
