Kiwi recreational drug users are being warned about a potentially deadly substance that has been found in DMT (Dimethyltryptamine).
DMT is a short-acting psychedelic drug that is found in many plants and animals, according to The Level.
It often comes in the form of a crystalline powder that is yellow, white, or off-white and has an effect similar to LSD.
Drug information organisation High Alert has issued a warning about the drug, saying some DMT in yellow powder form has been found to contain synthetic cannabinoid MDMB-4en-PINACA, which has been linked to a hospitalisation in Auckland.
It can cause serious harm and has caused deaths in New Zealand.
"High Alert has become aware of a new instance of this misrepresentation after a sample of yellow powder presumed to be DMT was submitted to a New Zealand Needle Exchange Programme (DISC) drug-checking clinic in Christchurch," the group said.
"This powder was found to contain MDMB-4en-PINACA. It remains unknown how widely this substance is circulating, but note that it has now been identified in the Auckland and Christchurch regions."
High Alert is urging Kiwis to be cautious with yellow powders and get them checked at drug-checking sites.
