"The synthetic cannabinoids in circulation are very dangerous.
"People may collapse or 'drop', foam at the mouth, or experience temporary paralysis. The effects are often worse if taken at the same time as alcohol and other drugs, if a person is unwell, or experiencing mental distress."
The drug is usually described as a white, off-white or yellow-brown powder. It is usually sprayed onto dehydrated plant material and smoked. It often has a chemical smell and sprayed plant material may be sticky - it is noticeably different from cannabis. It can be vaped or consumed orally.
Appearance and effects can vary among synthetic cannabinoids.
If you have heard any reports of the drug, you can report it via the "Report unusual effects" page at https://highalert.org.nz, using the alert ID N21/0019. All submissions are anonymous.
