⚠️ Community Notice 12th February 2026

A white powder sample expected to contain ketamine was found to contain both m**hamphetamine (42% free base purity) and ketamine (31% free base purity).

Ket's a dissociative anaesthetic, while m**h is a stimulant. If you were expecting to only consume ketamine, the presence of m**h and the combination of the two could lead to an unpredictable experience.

Since ketamine's effects tend to last 1-2 hours on average, and m**hamphetamine can last much longer (4-12+ hours), you may feel unexpectedly alert, restless, or unable to sleep. This could lead to redosing, thinking the ketamine has worn off - when in reality, m**hamphetamine is still active in your system.

While it's not unusual for CanTEST to see ketamine adulterated with small amounts of m**hamphetamine and other stimulants, the amount in this sample has the potential to cause greater harm.

Test it before you take it.

*Repost* because we're always getting questions about how we test drug purity at CanTEST as well as queries about what "high purity" really means.

There's always some uncertainty in purity determinations, because purities of street drugs can vary widely from sample to sample or pill to pill. They can be poorly mixed, inhomogeneous and cut or adulterated.

Our Chemical Analysts and Peer Educators put together this handy explainer to help bring a little clarity to drug purity results.

Test it before you take it, know the signs of overdose and never use alone. If you suspect someone has overdosed, call 000 for ambulance, use naloxone if you have it (it will only reverse an opioid overdose, but won't cause harm in the event of other types of overdose) and wait with the person until help arrives.

⚠️ 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).
