Legislation will force drug-makers to prove products are safe before they can be sold on the open market.

New code of practice and appeals committee created. A revolutionary law change which creates a legal recreational drugs market in New Zealand is expected to have near-unanimous support when it comes before Parliament.

The Psychoactive Substances Bill, introduced to the House this week, will force party-pill manufacturers to prove their products are safe before they come on to the market.

Legal highs are expected to be on shelves next year if the substances in them are found by a new Ministry of Health authority to be "low-risk".

The current legislation is seen as untenable because it cannot cope with the rapid growth in products such as synthetic cannabis, which had no testing requirements or controls over where it could be sold.


Associate Health Minister Peter Dunne said the new legislation would come into force by August, when a temporary regime which banned unsafe products would lapse.

He expected it to be a "game-changer".

Asked how officials would define a "low-risk" substance, he said: "These standards will be worked out by health experts and clinicians - not politicians - and that is the way it should be.

"But we are talking about pharmacological substances so there is always some element of risk when people choose to consume them. Individuals can have reactions," he said.

"But ... this legislation is [about] minimising that risk to the greatest extent possible and making things as safe as possible, and that is what the approval criteria will reflect."

Most parties were still considering their stance on the bill, but Labour and the Greens indicated they were likely to support it."
