Experts could one day advise Kiwi drug-users on how to get high without harming their health.
The government says it's open to considering the idea, amid criticism that it's not doing enough to keep users of illegal drugs safe.
In last year's Global Drug Survey, 63.5 per cent of New Zealand respondents said they had used cannabis, while scores of others used MDMA, cocaine, LSD, magic mushrooms and methamphetamine - despite their illegality.
Unlike with alcohol - where there are government-endorsed guidelines on standard drinks and safe consumption - no safety advice exists in New Zealand on how to take drugs while minimising the harm.
It's an area that Associate Health Minister Peter Dunne says the Ministry of Health could explore.
"I think particularly around some of the more serious drugs, there is some capacity to look at whether the Expert Advisory Committee on Drugs might give us a recommendation around that," he said.
"You wouldn't want to be encouraging [drug use], but on the other hand, you could give some guidance about what, in those circumstances, might be safe behaviour."
Dunne said he sees the issue in a similar light to the Needle Exchange programme, which provides sterile needles for users of injectable drugs.
The government has supported the programme for 30 years, helping slash rates of HIV and Hepatitis infections among drug users.
However, he added, "it's not something we've seriously turned our mind to at this point".
Drug Foundation executive director Ross Bell said the government should be doing more to help drug-users learn safe limits and minimise harm.
He suggested that it could support "drug-checking services" at festivals and nightclubs, "where users can scrape off a bit of their pill, or a drop of the liquid they've got, and have that tested, and verified 'this is ecstasy, or this is something else, or this is quite dangerous and we recommend you don't take it'."
"That's a model that some countries are looking at, that I think would be a similar pragmatic harm-reduction approach to what we've taking with injecting drug-use."
Global Drug Survey founder Dr Adam Winstock said instead of banning drugs, governments should be helping users learn their limits.
While the only way to avoid all harm was to avoid drugs, the risk could be "massively reduced for most people" if they followed the right health advice, Winstock said.
"The problem is there aren't really any sensible guidelines on how many drugs you can do in any space of time without running a high risk of ruining your life."
From last year's survey, Winstock created the world's first "safer use limits" for cannabis, an online tool for users to identify how at-risk they are, based on their consumption level and frequency of use.
He's planning similar tools for alcohol, cocaine, ketamine and MDMA.
