Unlike alcohol consumed on licensed premises, however, there's no guarantee that party drugs are what they claim to be. This summer in Australia there has been a spate of tragic drug-related deaths at music festivals.
Here at home, drugs intercepted at one of the biggest festivals of the year, Rhythm and Vines, were found to be laced with pesticides and other hazardous chemicals.
There's no denying that taking prohibited substances is an exercise in rolling the dice and hoping for the best. While such substances remain illegal, there is no way to guarantee their quality or to regulate their use.
By contrast, alcohol – that legal but still dangerous drug – is quality controlled and labelled to ensure that consumers are aware of its potency.
The laws and regulations surrounding alcohol consumption have been set in place to encourage people to consume alcohol as safely as possible.
There is no such safety framework for common drugs like cannabis and MDMA. Despite the risks, however, people will use them. All kinds of people. Wealthy executives, office workers, creatives, students, and everyone in between. If you believe the stereotype that drug-use is confined to beneficiaries and wayward kids, you are deluded.
As the abysmal failure of the so-called 'war on drugs' has proven, telling people not to take drugs is a waste of time. Human beings have been getting high for millennia, and contrary to the scaremongering of the morally indignant, the vast majority of drug users have experienced little or no harm.
There are an unlucky few, however, who have experienced serious harm as a result of their drug use, whether through poisoning, addiction, the severing of familial and other social bonds, loss of employment, or other potential consequences.
Countless studies have concluded that treating drug use as a health issue creates better outcomes for those people who struggle with their drug-taking – particularly those who would otherwise be criminalised and sent to prison, the university of crime – and for society as a whole.
Treating drug use as a health issue means focusing on the reduction of harm rather than the punitive (and pointless, given our ridiculous recidivism statistics) approach of condemnation.
One of the easiest ways to reduce harm from drug taking is to enable people to test the illicit drugs they're planning to use to check whether the drug is the substance they think it is, whether it's something else entirely, or whether it's laced with dangerous additives.
Combine such drug-checking with trained professionals giving information about possible side effects and other safety information, and tragedies can be averted.
Drug checking at music festivals – setting up stations where people can voluntarily take their drugs to test exactly what they are, and receive information about the risks and side effects of the substances they are using – seems like an absolute no-brainer to me.
Whatever your stance on drug use, surely no one wants kids in hospital – or dead – after ingesting rat poison, paint thinners or some other concoction of God knows what.
The legislative framework in New Zealand currently technically prohibits such drug-checking initiatives, although the service exists in a legal grey area, and some festivals do offer it while police largely look the other way.
Minister of Police, Stuart Nash, has recently come out in support of allowing festival-goers to check their drugs, though such a change in policy would require a change of legislation. A much needed one.
According to the New Zealand Drug Foundation, of the samples tested at New Zealand festivals last year, 20 per cent were not what the user thought they were.
A further 11 per cent were adulterated with other psychoactive substances.
When the substance was not what the user had thought it was, 52 per cent indicated that they no longer intended to take it.
Drug-checking undoubtedly alters drug-taking behaviour so that people make safer decisions.
Critics will argue that it provides a green light for users to take drugs – a ridiculous argument, given that people will take drugs anyway, whether they've been checked or not.
I know I'd much rather equip young people with information about the substances they're planning to take – and inform them if they're about to ingest a potentially fatal substance – than pretend that they'll just not use drugs because they're not supposed to.
It's time for us to get real and save lives.
