Associate Health Minister Peter Dunne has announced a temporary ban on a substance found in tested samples of synthetic cannabis K2.
Mr Dunne says K2 has been connected to a number of incidents including elevated heart rate, vomiting, anxiety and psychosis.
He says a substance identified as EAM-2201 was found in two K2 products seized by police from a shop and banned temporarily from this Thursday.
Mr Dunne says the fact the product is on the market tells him that the industry does not give a damn about the safety of its customers.
Mr Dunne says the Government has now banned 32 substances and effectively removed more than 50 products from the market.
