Helen Clark, former Prime Minister of New Zealand and former Administrator of the United Nations Development Programme, has given her support to a YES vote in the upcoming cannabis referendum. Today, the Helen Clark Foundation has released a report outlining the reasons for legalising and decriminalising cannabis. The Foundation is an independent, non-partisan, public policy think tank from Aotearoa and aims to contribute to policy debates on how to achieve a more inclusive, sustainable and peaceful society. The report’s release comes in the lead up to the referendum set for next year on whether to decriminalise cannabis and Clark has spoken about the need for informed debate around this issue. Lillian Hanly spoke with her and started by asking her to explain the findings of the report.
