A justice advocate and former National Party MP says this country's drug laws have been out of date for decades.
He is a signatory to an open letter from a high-powered group of dozens of individuals and organisations calling for drugs to be treated as a health issue.
Justice Minister Andrew Little has poured cold water on the calls to overhaul the drug laws.
He says the government is constrained by the results of last year's referendum on cannabis legalisation - despite it failing by just a slim margin.
Chester Borrows is the former head of the government's justice advisory group.
He spoke to Corin Dann.
