The council assisting the NSW Special Commission of Inquiry into Ice has recommended decriminalising personal drug use and possession.
The commission will also be told that a drug-testing trial should be introduced at music festivals and other ongoing fixed locations.
Ms Dowling will recommend the New South Wales Government implement a new policy emphasising drug use as "a health and social issue" rather than a criminal one.
The commission heard from more than 160 witnesses in hearings across regional areas including Lismore, Nowra, Broken Hill and Moree.
A further 35 people with lived experience of amphetamine-type stimulants gave evidence, mostly in private session.
