Abstract
The New Zealand government has proposed a new psychoactive substances regime, which will place the onus onto manufacturers to prove that their products pose a low risk of harm, prior to receiving approval which allows the products to be legally manufactured and sold. This is an innovative and unique development in the regulation of emerging psychoactive substances, and offers an alternative response to prohibition. The details of the new regime and how it will operate are now emerging, and this offers an opportunity to critically explore some of the issues related to the proposed new regime and to speculate on some of the outcomes. This paper brings together a group of New Zealand based researchers from a range of disciplines with experience of legal high' research to discuss this innovative new regime.
