A man and a woman have been arrested over the supply of synthetic cannabis after police seized 46 small bags of the drug at a Palmerston North address.
Senior Sergeant Steven Crawford says cash and items used for preparing and packaging the drug were also found during the execution of a search warrant on Wednesday.
"These substances are causing harm to our communities and it's important that we, as a community, work together to remove these products from our streets," he said.

"These drugs can be extremely dangerous and users can experience severe health issues."
The two were arrested at the property and will face various drug-related charges.
The woman, 45, is due to appear in Palmerston North District Court next Tuesday.
There were no details available concerning the man.
In July, as many as 10 deaths were linked to synthetic cannabis in Auckland.
The spate of cases led to Chief Coroner Judge Deborah Marshall issuing a public warning that the drug could cause seizures and many people had been hospitalised using it.
