⚠️ Community Notice 9th December 2025

A green 'punisher' press pill with a score mark on the rear was brought to CanTEST for testing, expected to contain M**A.
The sample was found to have a mass of 420mg, containing 38% M**A (equiv. to 160mg M**A free base).

A common dose of M**A is between 80-120mg. This means the amount of M**A in this pill is significantly more than the amount a person may usually expect to take.

The amount of M**A in every pill or capsule may vary a lot, even if they appear similar or are from the same batch, supplier or source.

Know the signs of serotonin toxicity, test it before you take it, start low and go slow.

Think someone's overdosed? Call 000 for an ambulance immediately.

⚠️ Isotocyanozene detections - a warning

CanTEST have seen three samples in Sept-Oct 2025 which contain the novel nitazene isotocyanozene (5-cyano-isotodesnitazene).

The samples presented to CanTEST all had a similar appearance (an off-white or slightly yellow powder inside a clear capsule). Two were presented as expected benzos, one as an expected opioid.

There's no readily available data on isotocyanozene globally. Info on this substance is extremely limited. If you're considering using it, or suspect you may have it, please not that there's no evidence-based information on safer use strategies for isotocyanozene.

Naloxone can reverse an opioid overdose, and nitazenes are responsive to naloxone but several doses may be required.

Naloxone's available for free, Australia-wide. Visit the link in our bio to find a location near you that's participating in the Take Home Naloxone program, or pop into CanTEST to pick some up.

Suspect someone may be overdosing? Always call 000 immediately for an ambulance (even if you have and use naloxone).

When you visit CanTEST, you're asked to place any phones or recording devices in a locker.
Don't put yourself and others at risk.

⚠️ Community Notice 17th October 2025

A baggie filled with white (unknown) powder was found to contain 5-hydroxytyptophan (5-HTP).

5-HTP is converted in the body into serotonin. The effects are generally quite subtle, and it's sometimes used recreationally after M**A with the aim of improving mood and reducing comedown effects.

However, there are serious contraindication risks that can cause serotonin toxicity and even death, such as mental health meds and other drugs like MAOI (which might be in chunga, mixed with DMT), SSRI/SNRI, TCA, atypical antidepressants with serotonin action, triptans, tramadol, tapentadol, lithium, serotonergic opioids, DXM, St John's Wort and other drugs like M**A.

Test your stuff, don't mix it, never use alone and know the signs of an overdose.

⚠️ Community Notice 30th September 2025

A broken white bar pill ('Xanax' press), expected to contain alprazolam and two brown capsules, expected to contain unknown benzos, were all found to contain 4'-Cl-deschloroalprazolam.

The white bar pill (Xanax press) also contained flubromazepam, clobromazolam and ethylbromazolam.

4'-Cl-deschloroalprazolam is a new benzo that's been found for the first time at CanTEST in these samples - both by itself and in combination with other benzos. There's very little info available about this substance, but it's structurally similar to alprazolam and was first detected in 2021 in both Aus and the USA.

In the counterfeit Xanax, it was the first time that this combo of benzos has been detected together at CanTEST. This particular combo includes a mixture of long and short acting benzos. In addition, flubromazepam can have an onset delay of up to 4hrs, which increases the risk of harm. Anecdotal reports from community members include long periods (up to 3 days) of blackout and memory loss.

Remember, Xanax bars aren't available in Australia, and Alprazolam in other forms is not readily available from Aus pharmacies. This means that you can expect most if not all 'Xanax' bars to be counterfeit, containing novel benzos or other substances.

❗ Community Notice 23rd September 2025

A capsule filled with white powder expected to contain an unknown opioid was found to contain the highly potent synthetic opioids metonitazene and protonitazene.

While both metonitazene and protonitazene have each been detected separately at CanTEST, this is the first detection of a combination of nitazenes in a single sample by a drug checking service in Australia.

Both metonitazene and protonitazene are known to be 50-200 times stronger than morphine. Even tiny amounts can cause overdose. It's difficult for health services to provide safer use advice due to the limited evidence that either of these substances can or should be used safely. Being informed, carrying naloxone, and staying with others can reduce potential harm.

❗ Community Notice 22nd September 2025

A capsule filled with white powder expected to contain an unknown opioid was found to contain the novel nitazene isotocyanozene.
While nitazenes have been detected in several parts of Australia, including at CanTEST in Canberra, this is the first detection of isotocyanozene at a service in Australia.

There is no readily available data on isotocyanozene globally.

The potency is unknown, however nitazenes are known to be 100s or even 1000s of times more potent than he**in or morphine.

Information on this substance is extremely limited. If considering using, please note that there is no evidence-based information on safer use strategies for isotocyanozene. Being informed, carrying naloxone and staying with others can reduce potential harm.
