It won't be long before thousands of young partygoers descend on summer festivals across the country.
And parents, you can rest assured knowing if your teenager decides to experiment with drugs they can get them tested on-site to be sure it's not a more sinister substance.
A spectrometer analyses a substance and compares it with a library of thousands of samples to give partygoers reassurance that the cocaine they just bought from an illicit dealer isn't something more dangerous.
"There's a lot of people taking a lot of drugs across New Zealand. It's about one in eight people who say that they do take illicit substances regularly," Know Your Stuff NZ general manager Casey Spearin told Newshub.
And thanks to a law change in 2021, drug testing charity Know Your Stuff no longer operates in a grey area. It's celebrating two years of legal drug testing.
"There's been a massive amount of growth in that time and we've seen thousands of people come through," said Spearin.
"We tested about 4000 substances last year and we know that people take about 80,000 doses of MDMA per week."
And the advantage of testing drugs on-site is that most people change their mind about consuming it - 68 percent in previous years.
The benefits of a legal framework aren't just being felt by drug takers but also by drug researchers who can use the data collected at testing centres to gain a better understanding of the substances doing the rounds on the black market.
"Because people are bringing in their illicit substances, it gives a slightly different view of drugs on the market that may have been seized by Customs or by police," Auckland University senior pharmacy lecturer Rhys Ponton said.
And that's even more important now that highly potent opioids like fentanyl and nitazene have been detected here.
As a drug harm reduction specialist, Ponton says the data from drug testing centres is more important than ever.
"The potency of these opioids is such a risk," Ponton said.
"A tiny grain of this is enough to be fatal. There was unfortunately a death earlier this year from that, as well as a whole spate of overdoses," Spearin added.
So, partygoers, unless you're prepared for a very bad buzz, it might pay to know your stuff.
