Drug campaigners say there's a big increase in crack cocaine use in West Dublin.
Children as young as thirteen are selling the drug and are being bought bicycles so that they can deliver the drug to areas like Tallaght, Jobstown and Fettercairn.
Community workers have raised concerns about the increased use of crack cocaine in the area.
Liam Collins from the Fettercairn Drug Rehab Project says "there are kids ... as young as thirteen in our community going around selling it, recruited by the top men, transport being supplied ... bicycles bought for the kidsto go around and deliver crack cocaine".
"Those people are not realising that they're creating mayhem for the families of those kids".
The rise of crack cocaine use in the locality is being put down to a number of things including newer supply and better management by dealers.
