One area in Tallaght in Dublin has 31 crack houses.
Tallaght Drugs and Alcohol Task Force has discovered the high number in Jobstown.
While there are up to 100 across all of Tallaght.
Crack cocaine usage has rapidly increased due to its price, potency, and addictive nature.
These locals describe what they experience:
Forced Sex And Prostitution
Addiction services say they're struggling to cope with problems linked to the highly addictive drug.
Larry O’Neill, CEO of South Dublin County Partnership, says dealers are going to extreme measures:
"These are not derelicts, these are homes."
"There can be children or families involved in those homes."
"They may not be directly involved but they'll be impacted by what's going on."
"We do actually have people who are walking out of recovery sessions and they're being followed."
He says people are putting drugs in their letterboxes or handbags.
Larry also says there's forced sex and prostitution to settle debts.
