The manufacturers of party pills and synthetic cannabis will have to prove their products are safe before they can be sold, under a law change expected to be announced on Monday.
Currently, the Government is able to temporarily ban specific ingredients in the so-called legal highs with 12-month temporary class drug orders, which classify the substances as the equivalent of Class C1 drugs.
The orders have seen products like synthetic cannabis Kronic, which could be sold in dairies, made illegal.
However, the orders are only issued after new products arrive on shelves.
The first orders, which came into effect in August last year - amidst concerns about the unknown health effects of combining untested psychoactive chemicals - are about to expire.
Associate Health Minister Peter Dunne will make an announcement about progress on regulating psychoactive substances on Monday morning.
The regulations, recommended by the Law Commission, require manufacturers to ensure their products are safe, with quality-control standards.
Ross Bell from the Drug Foundation says it's good advice that he expects the Government to take.
“We understand that the Government will be saying to the party pill industry, ‘if you guys want to exist then you have to jump through these hoops, prove that your product represent a low risk, and then we might let them be sold but we’re going to put some very tight controls in place’,” he says.
Mr Bell says the current drug law is over 35 years old - and needs updating.
A committee has spent the last 12 months assessing the temporarily banned substances.
