Gardai say hundreds of extra officers will crack down on street level dealers as part of a local anti-drugs strategy.
Operation Tara, which was rolled out in part last year, is focused on disrupting the business model of gangs.
Garda Commissioner Drew Harris says the hope is this will give communities more confidence in the police force:
"If we act locally, bring an individual who's recognised to Spain, an individual who's peddling drugs, bring them to justice, that adds actually I think to the confidence of a local community, that actually there's a law enforcement response to this and that they can have confidence in what we're doing."
