Drug Foundation executive director Ross Bell said fewer convictions for low-level drug offences is the right direction but the Government needs to make clearer policy changes into law.
"It's good police are shifting their priorities on to more important things, but what that means is the Government is being irresponsible. It's letting the police do what should be done through policy and enforcement practices, rather than it become a government policy and ultimately a change in the law."
Police introduced a formal pre-charge warning aiming to reduce the number of low-level offences going through court. A pre-charge warning results in an offender being processed at a police station, but the warning does not appear on a criminal record.
In a statement, police spokesman Tim Anderson said: "Our officers have discretion to warn for offences and police deal with these on a case-by-case basis. In terms of an arrest, every case is judged on its merits and sometimes an arrest is made to enable that individual to get some treatment for the drug problem they may have at the time."
