More than 30 Jersey police officers have been carrying out early-morning raids, targeting those involved in serious crime include drugs and domestic abuse.
Two arrests were made, with devices seized.
Evidence during one search also identified evidence of other offending.
Detective Inspector Paul Ryan, who leads the drugs squad, said:
"The purpose is to protect the public, safeguard vulnerable victims, and make the island safer.
"All those (offending) have very different impacts for the victims, and of course we've got considerations for the suspects as well.
"Drugs cause a lot of harm to our community. Criminals are making a lot of money out of drug-dealing in Jersey, and we want to take the dealers out and the suppliers out at the same time so we can protect vulnerable victims in Jersey."
The warrants were all based on intelligence received. Jersey Police receive around 7,000 reports of information a year.
Detective Inspector Callum O'Connor, in charge of the Force Intelligence Bureau, said:
"My joint team - which is Customs, police staff and police officers - develop those information reports into actionable intelligence.

"We then disseminate that or task that internally, so to Paul and his team, but we also share that with key partners - Customs, Children's services, Health and also nationally and, when required, internationally as well.
"It can take days, it can take weeks, it can take months, but sometimes we receive that really exceptionally high-grade intelligence and, when it comes to looking after the most vulnerable in society, we will take immediate action."
