Drugs such as heroin and ice could be decriminalised in small amounts in the ACT.

Labor backbencher Michael Pettersson will introduce a private member’s bill to the Legislative Assembly early next year.

The proposed laws would work in a similar way to how ACT Policing dealt with cannabis possession before it was legalised.

The legislation would set a possession limit of two grams for cocaine, ice and heroin half a gram for ecstasy.
