Class A and B drugs were found at a Rodbourne address by police officers armed with a warrant.
A man is in custody following the execution of the warrant in Barnham Court, and a police spokesperson said high value goods, believed to be the proceeds of crime, were also recovered.
Officers acted this morning - July 31 - following increased patrols in the area and information from local people.
The spokesperson said: "A 50-year-old local man has been arrested on suspicion of being concerned in the supply of class A and B drugs and money laundering and is currently in custody in Gablecross police station for further questioning."
Acting Sergeant Nathan Martin said: “We are aware of the concerns expressed by local people in Rodbourne in relation to illegal drug use in the area in recent weeks, and in response to this we have been conducting a number of regular overt and covert patrols to provide both reassurance and tackle those intent on supplying drugs within our communities.
“We’ve had some good results on the back of this work combined with the information provided to us by residents, and today we were able to arrest a man following a warrant at an address which has been causing concerns for neighbours in recent weeks.
"We will be seeking a closure order for the address over the next few weeks.
“The supply of illegal drugs can be detrimental to those directly and indirectly involved and we are intent on tackling those who offend.
"I hope this result provides reassurance and encourages others to report any issues they may be experiencing in their neighbourhood."
Anybody suspecting drug activity in their neighbourhood can report those concerns on 101 or anonymously through Crimestoppers on 0800 555 111.
