Cathinone C86 identified as eutylone

The substance found and alerted by KnowYourStuffNZ in testing earlier this month, previously known only as C86, has now been identified as eutylone.

Eutylone, also known as bk-EBDB or n-ethylbutylone, is a stimulant in the cathinone family (sometimes called “bath salts”). It was first synthesised in the 1960s and first reported to  European Early Warning Systems in 2014. Reports of recreational use began to appear about 2 years ago.

KnowYourStuffNZ detected the first sample of this substance in December 2018. We have detected three samples of eutylone this year, in locations from upper North Island to lower South Island. All were obtained as MDMA, and were described as a white powder that tends to clump together – however it may also be around in other formats. Anecdotal reports from NZers who have used this substance thinking it was MDMA suggest it may be responsible for several hospitalisations.

In the absence of a spectrometer, reagents can be used to test for the presence of eutylone. Testing with the Marquis reagent will give a yellow/orange colour, and the Mandelin reagent turns a muddy greenish-brown. Meanwhile if a substance contains MDMA, both Marquis and Mandelin reagents will turn black. It is important to note that other cathinones have been found mixed with MDMA, so a positive test result for MDMA does not mean a substance is unadulterated.

Eutylone is not well researched and very little information about it is available. The following information has been put together from a combination of user reports, safety data sheets, and references in scientific journals.

Dosage:

Oral doses of between 35mg and 150mg have been reported, however the average dose is reported as 60-100mg. 150mg was described as ‘very intense’.

Duration

4-6 hours

Effects

The effects are described as subtle, calming, social, serotonergic (loved up), euphoric, and not particularly stimulating.

Sensations of physical warmth and tingling were described in several reports. One user reported feeling unusual heart activity.

Dangers/negatives

Users reported redose compulsion, with most redosing every 1-2 hours.  Because this is a stimulant, repeated redosing can lead to restlessness and insomnia, and eventually psychosis if the user does not sleep.

Safety Data Sheet information suggests it may be irritating to mucous membranes.

Users have reported raised heartbeats, and as it constricts blood vessels this substance can also raise blood pressure and cause numb or cold extremities.

Eutylone has been identified as present in one death in the US, however the victim had also taken fentanyl and thus the role of eutylone in the death is not clear.

Harm reduction information

Avoid snorting this substance.

Avoid taking with other stimulants (eg cocaine or MDMA), dissociatives (eg ketamine, DXM, or GHB/GBL), or alcohol.

If you intend to take eutylone, be aware that it is a very new substance with little confirmed information available, and therefore approach with extreme caution. Take only a fraction of the expected dose and wait at least an hour before taking more.

Always make sure a trusted person knows what you are doing.

If you experience dizziness, nausea, racing heart, or numbness in the extremities, seek medical help and be honest about what you have taken.

Suspected high-dose MDMA pills tested by KnowYourStuffNZ 2018/2019 season

KnowYourStuffNZ has found pills containing potentially dangerous high doses of MDMA during the 2018/2019 festival season. These pills were found at events throughout New Zealand.

They should be approached with caution. Users are advised that the only way to guarantee safety is to not take them. For those who do choose to take them, our recommendation is to only take a third of a pill at most, and wait at least an hour before considering taking any more.

These pills have been tested to contain MDMA and a variety of fillers. No other psychoactives have been detected in these, despite anecdotal reports that they also contain ketamine.

A common dose of MDMA is around 80-120 milligrams, depending upon a user’s body weight. Some of the pills that KnowYourStuffNZ have tested this summer contained up to four doses in one pill.

Taking too much MDMA can result in a very unpleasant experience, health risks, and sometimes even death. If you or someone you know has taken one of these pills and experiences dizziness and vomiting, a sharp rise in body temperature, muscle cramping, heart palpitations, seizures, or unconsciousness, seek medical attention immediately.

Please note that the amount of MDMA present is an estimate only as our technology cannot directly measure dosage or purity. The spectrometer can provide a rough percentage of MDMA content in a sample and we use this combined with the weight of the pill to reach these estimates. The estimated dosage should be treated as an indication only and we recommend always erring on the side of caution.

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.
