The Drug Foundation wants urgent action, with meth and cocaine consumption reaching record levels

Police wastewater testing between June and September reveals levels of both drugs were at the highest volumes recorded - since the programme began six years ago.

Chief Executive Sarah Helm says harm reduction, addiction and acute healthcare services all need to be prepared for an increase in need.

She says it's likely people are using larger amounts of meth, instead of an increase in the number of users.

Sarah Helm says they're expecting to see an increase of hospitalisations from acute toxicity, heart health impacts or psychosis.
