Figures from the Health Research Board show the number of people seeking treatment for using the drug has jumped 594 percent - from 173 cases in 2017 to 1,201 last year.
Sinn Fein councillor, Daithi Doolan, from the South Inner City Drug and Alcohol Partnership, says it's affecting individuals and families - with whole communities held to ransom by dealers.
He's calling for increased funding to support local community projects working with drug-rehab schemes.
