2019-2020: Cathinones and high-dose MDMA still prevalent

Drug checking results from the 2019-2020 festival season have now been analysed. This summer, KnowYourStuffNZ volunteers tested 1,368 samples of illicit substances brought voluntarily for testing at 22 events. This is a substantial increase from last summer.

Overall, almost 1 in 10 samples were not what the owner thought they were. When a substance was found to be not what the owner thought it was 52% of people said that they would not take the substance.

2% of the substances thought to be MDMA were found to contain the cathinones n-ethylpentylone or eutylone. N-ethylpentylone has been associated with deaths overseas and mass hospitalisation in New Zealand. Eutylone has been found throughout New Zealand in the last 18 months, and is a fairly new substance with unknown risks. Testing also revealed that 1 in 20 MDMA pills tested contained two or more doses of MDMA.

Responses to a client survey showed that 80% of respondents have had past experiences with drugs that were not what they were thought to be, describing unpleasant and frightening experiences. Our analysis has consistently shown that people are much less likely to take a substance when testing shows it is not what they thought it was, and 85% of surveyed clients said that after using the service they are more likely to get drugs tested before taking them.

The survey also showed significant support for expansion of the service, with requests for it to be available both at all major festivals and at regular clinics throughout the year in NZ cities. These statements align with those of Police Minister Stuart Nash, who has been a vocal supporter of our work.

Introducing High Alert

We’ve been advocating for a drug Early Warning System for New Zealand for years, and it’s finally happened! Introducing High Alert – where you can check for warnings and notifications about what’s out there and help keep yourself safe.

So, who’s behind High Alert?

It’s a collaborative effort between a network of organisations who regularly encounter and respond to drug issues. Known as Drug Information and Alerts New Zealand (DIANZ), this group works together to reduce drug related harm. DIANZ issues alerts and notifications when something is identified that poses significant harm to people who use drugs, and gathers and analyses data from a variety of sources in order to monitor drug trends. .

KnowYourStuffNZ is part of DIANZ. We support the work DIANZ is doing by providing information about potentially dangerous substances we have found, and helping with decisions, alerts, and notifications.

Key info about High Alert:

· It acts as a central point for all drug related data, which will help to quickly and effectively respond to immediate and future risk in drug harm.

· Anyone who has experienced unexpected or concerning effects from drugs can share their experience through High Alert. This will help keep others safe. Data collected via the website is entirely confidential. It won’t be used to pursue prosecution.

· Alerts and notifications will be published on the website to inform the public of any increased health risks presented by new drug trends or novel substances.

· Education and specific harm reduction advice based on the latest trends will also be published on the website.

· All of this aims to reduce drug-related harm.

The High Alert website publishes alerts and general harm reduction information for people who use drugs, health practitioners, and the general public. It also allows people who use drugs to report unexpected or concerning effects from drug use with no risk of prosecution.

Note: we will continue to provide our own alerts when public safety requires a speedy response to emerging dangerous substances, such as over New Years. However, we encourage you to check High Alert regularly – it’s been a long time coming and we’re happy it’s finally here!

Be a K know-it-all

At KnowYourStuffNZ we’ve seen quite a bump in the use of ketamine over this festival season (pardon the pun). As we’re responsible ponies who like to make everybody safer, we want to give some easy to digest, legit information about K: no horse-play here. 

Here’s what our friends at The Loop have to say:

“Ketamine is what is known as a dissociative anaesthetic which gives users a sense of detachment from their body and surroundings.”

It’s usually found as a white powder and taken in ‘bumps’ by snorting up the nose (insufflation). A common dose is around 50-80mg, with anything over that considered a strong or heavy dose.

Effects start trotting along within 7-20 minutes, hitting a gallop at about 30-60 minutes, and after-effects lasting from 2-12 hours. Ketamine is still in your system even after you stop feeling effects so having more can produce stronger effects than expected.

Let’s get it all lined up for easy consumption:

Effects Include:Risks Include:
Feeling light and bouncy as a foalAccidents while intoxicated
DelusionsDisturbing hallucinations
Visual hallucinationsPsychosis
Vomiting (Especially if combined with alcohol)Nasal damage
At high doses it leads to the “K-hole”: Users seem unresponsive to others, but experience vivid hallucinationsSlowed breathing, inability to look after yourself, vomiting and potentially death

In our work testing and giving out advice at festivals around Aotearoa, we’ve noticed that a lot more people are horsing around with ketamine in 2020, and a correlated upswing in reports of ketamine-related harm.

Some people are ending up in the K-hole even when they don’t want to, by repeatedly ‘bumping’ the same amount or increasing amounts. The cumulative effect is something to really be aware of friends: reduce the size of each bump if you are going to repeat dose.

Don’t mix ketamine with other drugs: depressants like alcohol increase the risk of passing out and choking on your own vomit. When mixed with stimulants like MDMA it can cause blood pressure spikes. 

If you are seeking the K-hole make sure you are with people you trust. Have a designated   trip-sitter, or at least someone who’s not also K-holing, to make sure you aren’t a victim of “foal play” while you’re incapacitated.

A significant number of regular users experience bladder problems – including UTI’s, cystitis, and a risk of ulcerated bladder requiring bladder removal. We recommend keeping K special and your bladder intact by using it only occasionally.

Once again, because we’ve seen it a lot: don’t mix Ketamine with alcohol. One of the biggest risks is impaired judgement from alcohol mixed with the lack of coordination and dissociation from Ket, leading to all sorts of bad times.

Remember folks, we do regular free drug testing with an infrared spectrometer in various cities around the country: don’t look this gift horse in the mouth! Be sure of what you’re putting in your body.

Wash your hands, cough into your elbow and don’t take MDMA – advice for a pandemic

As COVID-19 progresses through New Zealand it’s important to understand how we all have a responsibility to help protect ourselves and others. We each have a responsibility to both stop the spread and flatten the curve, and part of that is being aware there are some ways that taking MDMA can increase your risk of infection.

How can MDMA increase your risk of contracting COVID-19?  

External: where you are and how you act  

  • The environment you take it in – crowded parties or packed festivals with close contact to multiple people around you makes disease transmission far easier. While we are at Level 4 this shouldn’t be a consideration, but remember one of the most effective ways to minimise the spread of COVID-19 is to practice social distancing.
  • The changes to your behaviour – empathogenic effects of MDMA can lead to feelings of closeness and craving for interpersonal intimacy. This makes social distancing harder to practice when using MDMA.

Internal: what happens inside your body 

MDMA is an immunosuppressant, meaning it temporarily weakens your immune system.

How? You can think of MDMA as changing the “chemical background” under which your immune system functions. It makes sense that a substance that would change your brain’s chemistry would also change the chemistry of other parts of your body. 

This change of the chemical background leads to suppression of the activity of disease fighting cells. It also alters patterns of release for chemicals that transport information around your body about where infection is, and the most effective way to fight it. 

Remember COVID-19 affects people with weakened immune systems more harshly. Weakening your immune system makes you both more likely to both contract and spread the virus.

The immunosuppressant effects of MDMA last for about the same length of time as the drug stays in your body – up to 48 hours.

Long term effects of MDMA on the immune system. 

People that take MDMA regularly tend to have higher rates of general illness and infection. A 2002 study from the Recreational Drugs Research Group of East London University found that 9% of people that took MDMA 10-99 times, and 35% of people that took MDMA over 100 times reported increased infections. If you take MDMA on a regular basis consider yourself more vulnerable to illness and make sure to follow the Ministry Of Health recommendations to keep yourself safe.

Harm reduction for the next few months 

Remember that the only way to guarantee safety from drug harm is to not use drugs. Due to COVID-19 this is especially true right now, as the risk of harm to both you and your community are increased.

However if you choose to take MDMA, we suggest you do the following:

  • Treat taking drugs similarly to preparing food: Wash your hands for 20 seconds, and wipe down all surfaces that will come into contact with what you are going to take
  • Avoid snorting MDMA. Sharing straws or banknotes is a surefire way of passing viruses on to your friends, as well as damaging the lining of your nostrils which makes you more susceptible to infection. Don’t share other equipment such as bongs, pipes, straws, etc
  • After taking MDMA, your immune system will be compromised for at least 48 hours. Be extra cautious and double down on Ministry of Health guidelines for safety. The highest risk to you is while you’re high, as this is when the effects on your immune system are strongest. 
  • Ideally you will already have the next day set aside for comedown. Consider extending and using this time to keep yourself socially isolated and let your body readjust. 
  • Remember that MDMA causes hypersociability, but now is not the time for group hugs, cuddle puddles or other forms of close contact with people outside your bubble. Social distancing is here to stay for the next little while, so avoid large crowds such as festivals or parties where you will come into close contact with large amounts of people.

Remember that this is not just about avoiding getting sick yourself. COVID-19 spreads very effectively from person to person, so risks you take are not just personal, but they could affect other people and members of your community. Stay in your bubble and look out for your friends, neighbours, and fellow humans. This will pass and we have to keep ourselves and the people around us safe until it does.
