Fewer Northlanders are showing up to the emergency department with psychoactive substance issues since a ban on the drugs came into force last year.
The Psychoactive Substances Act, which passed in 2013, regulated the availability of substances but allowed some products to stay on the market. The Psychoactive Substances Amendment Bill, passed in May last year, ended that interim product approval.
Northland District Health Board (DHB) chief executive Nick Chamberlain said three people presented in emergency departments for issues with the banned drugs in the year following the amendment.
There were no synthetic cannabis related admissions to Northland DHB's specialist detoxification service, Timatanga Hau, over that period.
Dr Chamberlain said 17 people presented in emergency departments with psychoactive substance issues the previous year and there were two admissions to Timatanga Hau, where synthetic cannabis withdrawal was a component of the patient's management.
