Nosebleeds are the least of your worries – why snorting is a bad idea

Know Your Stuff-36

Remember when you were four and your Mum used to tell you not to put things up your nose?  Turns out lots of kiwis didn’t listen. According to Adam Winstock of the Global Drug Survey, 30% of kiwis who use MDMA insufflate (snort) it. That’s nearly twice the global average.

There’s a general view out there that snorting MDMA gives you more ‘bang for buck’ because when snorted the high comes on faster and more intensely.  However it also wears off faster, leading to higher likelihood of redosing – so over the course of an evening a user may end up taking more than usual, which is both expensive and risky. Snorting also carries its own set of risks:

  • Putting dry, potentially irritant powders on the nasal lining can lead to injury, loss of sense of smell, and long term respiratory problems.
  • When you snort a substance much of it goes directly to the bloodstream, bypassing the stomach and liver filters. This is what leads to the faster, more intense high.  However this lack of filtering can also exacerbate the negative effects of the drug, such as anxiety and nausea.
  • Faster routes of administration are associated with higher risk of forming dependence.
  • What if it’s not the drug you think it is?

This last one is a real concern in New Zealand. By now it’s old news that cathinone substitution is an issue here. We’ve talked about it at length this summer. We’ve found cathinones in samples presumed to be MDMA and in ones obtained as cocaine, both substances commonly snorted by kiwis.

Remember how we said above that a faster, more intense high can also exacerbate the negative effects? If the ‘MDMA’ is actually n-ethylpentylone and you snort 100mg of it, you’ve just bypassed the stomach and liver filters on a triple dose and you’re most likely in for a faster, more intense, up to 36-hour-long very unpleasant time that may well land you in hospital or worse. 


We hear this story far too often – someone snorts what they think is MDMA and then comes to us with a list of scary symptoms ending with “That definitely wasn’t MDMA.” The bottom line is that these people are lucky to be alive. While they have probably learned their lesson, there are still many people out there who snort powders without knowing how risky it is.

To lower your chances of death, remember the following:

  • Listen to your Mum – don’t put random stuff up your nose
  • Don’t let your friends put random stuff up their noses either
  • Unless it’s been tested, it’s *all* random stuff.

Stay safe out there NZ.

Deliberately Deceptive Drug Mixtures Found This Summer

Testing by KnowYourStuffNZ this summer has revealed that some festival goers have been sold deliberately deceptive mixtures of drugs. Some mixtures were sold as MDMA but contained only small amounts of MDMA alongside more toxic chemicals. Some mixtures were sold as cocaine but instead contained mixes of stimulants and anaesthetics.

Our testing has shown that the quality of substances sold on the illicit market is variable and poor. In many cases, substances sold are not as expected. However, this summer we have seen mixtures that appear to be made up to deliberately mislead people.

For example, cocaine produces a numbing effect in the nose and mouth. We have seen mixtures that contain no cocaine at all but only benzocaine and cathinones (“bath salts”). The benzocaine (a local anaesthetic found in cough lozenges) produces the numbing effect; the cathinones duplicate the stimulant effects. In these cases, the cathinones were n-ethylbuphedrone and ethylmethcathinone, which have longer duration and more toxic effects than cocaine.

Several samples supposedly of MDMA were a mix of MDMA and cathinones. We believe that these mixtures were made up to fool reagent testing – the MDMA produces dark colours with commonly-available reagent tests, masking the colours from the unwanted cathinones. These combinations are particularly risky due to the different potencies of these substances. One sample seen was 50/50 mix of MDMA and n-ethylpentylone (a new substance that we called “this summer’s crap drug”). An active dose of MDMA is around 100 mg; a dose of n-ethylpentylone is 30 mg. If someone weighs out 100 mg of this mixture, they will take nearly two doses of n-ethylpentylone (already a risky dose) and only half a dose of MDMA..

Inevitably, unregulated markets have poor quality control and unscrupulous dealers will sell products that maximise their profits, putting consumers’ health at risk. Pill testing allows drug users to discover the quality of their purchases and avoid these risks.  We recommend that all drug users test before they ingest any substance.

KnowYourStuffNZ uses both reagent testing and infra-red spectrometry to discover these mixtures. However, an infra-red spectrometer costs $50,000 and this is not accessible outside of events that KnowYourStuffNZ attends.

Reagents for testing are available for much more affordable prices from suppliers such as Hempstore, but as the mixtures found this summer demonstrate, reagents have their limits. They would have identified the substitute cocaine; they would not have detected the adulterated MDMA. We still recommend reagent testing to drug users despite the limitations, as some testing is better than none – however the results from reagent testing are no guarantee and all substances should be approached with caution.
