There have been eight deaths in Auckland related to synthetic cannabis use in just over a month.
The latest was a 24-year-old Papakura man who became seriously ill after he was believed to have been smoking synthetic cannabis. He was taken to Middlemore Hospital in an ambulance and died.
In each of the seven previous deaths, the person was believed to have used synthetic cannabis recently or was found with the drug on them, police and the chief coroner say.
