The number of home drug kitchens found by police has dropped by more than 50 per cent over the last five years, however police say they have not won the war on drugs.

Statistics have shown the total of drug offences has almost doubled between 2011 and 2017, with authorities attributing this to the emergence of the “dark web” and portable drug labs.

Detective Senior Sergeant Sasha Finney said that although there are dedicated teams working against these emerging trends, “it will continue to provide [them] with challenges”.
