Drugs worth almost £1.5 million and cash totalling £44,000 have been seized during a police crackdown on street dealers.
A total of 357 suspects were arrested, 78 of whom were charged, during the three-month operation.
PSNI officers also carried out 1,823 searches and made 704 seizures.
Assistant Chief Constable Will Kerr said: “We’ve invested a considerable amount of time and effort into this campaign and it has delivered worthwhile outcomes.”
Herbal cannabis was the principal drug seized with an estimated £1.17 million worth taken off the streets between February and April, ACC Kerr said.
The senior officer added: “Although this operation has concluded, drugs will remain a policing priority.
“We will continue to disrupt and arrest those involved in the sale and supply of drugs, bring individuals before the courts and work with communities and partner agencies to reduce the threat of harmful and illegal activity.”
Justice Minister David Ford described drug dealers as a scourge on society.
He said: “I commend the PSNI for their continuing work to remove drugs from our streets and bring perpetrators to justice.
“However, there is no room for complacency, as the impact of illicit drug use on individuals, families and communities can be devastating.”
The policing operation was run in conjunction with a public information campaign highlighting the dangers of illegal drug abuse.
Crimestoppers reported a 23 per cent increase on the number of anonymous tip-offs received regarding drug dealers.
