South Auckland health officials have warned that a new batch of synthetic cannabis may carry major side effects including "life-threatening" seizures.
It comes after a warning last week by Auckland District Health Board and St John's Ambulance Service following seven sudden and unexpected deaths from the drug.
Middlemore Hospital's Dr Chip Gresham said the hospital has seen at least six cases over the last few days, including one man who is in a very serious condition following prolonged seizures.
"We do not typically see many cases of severe health related issues arising from synthetic cannabis at Middlemore Hospital. However, when we do, it usually comes in waves," he says.
"This is because the way synthetic cannabis is manufactured.
"No one knows for sure what's in it, the amount of active substance in each bag, or the effect it will have."
He says every time there is a new batch, it puts consumers in even more danger.
"Occasionally we get new brands or batches that come through and whatever new batch or brand that's out there is putting people's lives at risk by causing seizures and other serious medical problems," he added.
If people have concerns about family members or loved ones who are using the drug then they are encouraged to ring the Alcohol and Drug Helpline on 0800 787 797.
