A number of people have been hospitalised in the Tipperary region after eating cannabis jellies.
Gardaí seized the jellies, as well as vape oil and cash, after searching a house in Clonmel on New Year's Eve.
They contain a substance known as synthetic cannabinoids, and can result in rapid heart rate, seizures, vomiting and hallucinations.
The HSE says there's a high level of risk associated with THC edibles currently being sold illegally in Ireland.
