Glenn Dobson: Drug Detection Agency CEO on the increasing number of positive cocaine and amphetamine results in workplace testing

Class A drug use is soaring in New Zealand. 

The Drug Detection Agency's latest workplace testing results show amphetamines are increasingly showing up, making up 32.7% of positive results nationwide – rising to 44% in Southland. 

The use of cocaine specifically is also increasing, with positive tests up 68.5% year on year and a 375.8% increase in Canterbury. 

Chief Executive Glenn Dobson told Mike Hosking that cocaine use on a global scale is up massively, with stats from Australia and the United States showing a similar picture. 

He says the significant increase in the South Island shows the supply is potentially fluid – suppliers moving around the country more than they have in the past.
