A dangerous new drug gripping the capital has forced the Capuchin Day Centre for the homeless to increase its security cover.
Brother Kevin Crowley (79) and his team hand out breakfast, dinner and food parcels to hundreds of people who are homeless or in hardship and come for help at the centre in Bow Street in Dublin 7.
But he has noticed the effects of a new drug which he said is making its users "crazy".
"In recent times the drug situation has got very bad and there seems to be a new drug out at the moment which is driving everybody crazy," Br Crowley explained.
"As a matter of fact we had to employ extra security in recent times," he added.
The drug that Br Kevin referred to is believed to be synthetic substance called TVP or MDPV - a psychoactive stimulant that leaves users hyper and paranoid.
"Addicts are taking it after being told by their suppliers that it is a different drug - crystal meth," Tony Duffin of the Ana Liffey Drug Project told the Herald.
"Because it is both a stimulant and hallucinogenic it can be very dangerous for users."
Mark Kennedy of Merchants Quay drugs project said users can get very agitated and paranoid on the drug very quickly.
"This newer drug can heighten mental difficulties and exaggerate them," he said.
Apart from the mental effects, the dangers of overdose and blood-borne viruses such as HIV are massive.
A member of Br Kevin's team told the Herald that the drug is having a "major effect" on behaviour of some of the people coming to the Daycare Centre for help.
