Three people have been arrested in a series of drugs raids in the Holyhead and Valley areas.
Police carried out four searches as part of a 'day of action', prompted by an investigation by neighbourhood officers.
A haul of suspected cocaine and cannabis was seized during the raids on Thursday.
The three suspects, questioned in connection with drug supply, have since been released under investigation while enquries continue.
PC Andrew Jones from North Wales Police said: "These results come after community concerns about the supply of cocaine and ketamine in the area."
"People who bring drugs into our communities do not care about the pain and misery they cause, only the profit they can make from exploiting vulnerable people."
"We thank members of the public for their continued support and information that helps us to take drugs off the streets of Anglesey."
"We encourage residents to continue to come forward with any concerns around drug supply in their community and we will fully investigate information received."
