Police in Pembrokeshire have arrested eight people over the last week in connection with several drug-related offences.
The arrests have also involved the seizure of significant quantities of drugs.
"These arrests and seizures emphasise the commitment of officers within Pembrokeshire division to crack down on the suppliers of drugs," said a police spokesman.
"We would also wish to emphasise the harm that taking drugs can do, not only to individuals, but to families and communities alike, and we all have a duty to prevent these drugs becoming widely available in our county."
Anyone who may have information on anyone who is taking, producing or supplying controlled drugs should contact their local police station or contact Crimestoppers on 0800 555 111
