The party currently has no formal position on recreational or medicinal use of cannabis.
Labour's review of its position comes as Associate Health Minister Peter Dunne approved an application for a cannabis-based product for just the second time - for a patient with severe Tourette's Syndrome.
The guidelines for approving medicinal cannabis products are currently being reviewed by the Ministry of Health.
Mr Dunne said yesterday: "Although it has been suggested that the information requirements for applications are too stringent, an aspect I expect the current guidelines review will look into, the application I received ... suggests that they are not an impediment to robust, clinician-led, assessment-based approaches."
At present, patients can apply to the ministry to get access to one form of medical cannabis, Sativex, which has been cleared for use in New Zealand. Applications for non-pharmaceutical-grade cannabis face a stricter set of criteria and approval is only granted to severely ill patients.
