Three people were arrested on suspicion of drug offences after police raided a property in Hunstanton.
Officers seized a quantity of suspected Class A and B drugs after executing a search warrant at an address in the town on Thursday.
A sniffer dog was used to carry out a search of the premises.
One officer involved in the operation later tweeted: 'PD Toby located a quantity of Class A substances during a search warrant in Hunstanton this morning.
'Some great teamwork with @KingsLynnPolice Team 3 resulting in three arrests.'
The seizure is the latest in a string of drug busts in Hunstanton and neighbouring Heacham.
Last week officers seized Ketamine from a woman they arrested in the West Norfolk resort.
It came a day after a man was arrested for possession of cocaine.
When officers searched his property, they also found a quantity of cannabis.
