Those who use medicinal cannabis illegally are concerned that their supplies are running out.
Radio New Zealand reports that 1200 cannabis plants in Northland were poisoned last month in an aerial cull that has been blamed on police.

She wants to see the Government subsidise the drugs so that people can actually use it.
