Multiple people have been hospitalised in Auckland in the past 24 hours after taking synthetic cannabinoids, prompting an urgent warning from health authorities.
Drug watchdog High Alert said the sudden spike in harm was "of serious concern" and reflects a wider trend of increased hospitalisations linked to synthetics across New Zealand in recent months. The harmful batch was believed to be circulating throughout Auckland and possibly other regions.
The substance responsible had not yet been identified. Further analysis was underway by PHF Science (formerly ESR), and updates will be posted on the High Alert website.
Synthetic cannabinoids — often called "synthetics" or "synnies" — are chemicals sprayed onto plant material and smoked. They could vary widely in strength, making it difficult to predict effects.
High Alert said even small doses could be dangerous and what was safe for one batch might be fatal in another.
Reported symptoms could include a fast and irregular heartbeat, sedation or drowsiness, slowed reaction times, difficulty breathing, nausea or vomiting, seizures, tremors, temporary paralysis, confusion or loss of touch with reality, paranoia, anxiety and panic attacks, and loss of consciousness.
Combining synthetics with alcohol or other drugs increased the risk of overdose.
Authorities urge anyone who collapses, stops breathing, or has a seizure after taking the substance to call 111 immediately.
