Western Australia's opposition leader is promising to fight a police bid to divert more meth users away from the courts and into rehabilitation programs.
Police Commissioner Chris Dawson believes people caught in possession of small amounts of methamphetamine should not necessarily face criminal charges, arguing they should instead receive education and support for addiction.
Programs already exist to divert users found with less than 10 grams of cannabis or 0.5g of meth away from the courts.
"(That) has proven to be quite a successful model. I think it's worthy of expanding," Mr Dawson told Nine News.
"Simply accumulating possession-type drug offending and then putting them back before the courts without education or rehabilitation, I don't think is the complete answer."
The state Labor government has indicated it will consider supporting the proposal.
Opposition Leader Liza Harvey says it is a "dangerous pathway" and has accused the government of being soft on crime ahead of the 2021 election.
"People and tourists are scared to walk down the streets of the CBD because of the violence associated with meth," Ms Harvey said.
"It not only leads to violence, but it destroys families and is a major contributor to the homeless crisis now gripping our state."
Police Minister Michelle Roberts said Ms Harvey had expanded the diversion program when she herself held the portfolio under the previous Liberal government.
"It's proven yet again that she's not across her brief, she didn't know what happened when she was police minister and she doesn't talk to her colleagues," Ms Roberts told 6PR radio.
