Victoria has slammed the federal government's move to drug test welfare recipients and has called on MPs in Canberra to vote down the legislation.
The state's Mental Health Minister Martin Foley says drug testing will not help people who need rehabilitation or housing.
"We won't demonise people here in Victoria, and we will continue to roll out our record investment to give people a home and support they need to get back on their feet," he said on Thursday.
More than 40 per cent of rough sleepers in Victoria are on Newstart or Youth Allowance.
Federal Social Services Minister Christian Porter on Thursday put forward a bill including a two-year program to drug test 5000 new recipients of Newstart or youth allowances in three locations.
