Concerns have been voiced over plans for injecting centres in the city.
A bill to allow such rooms is still being put together by the Drugs Minister Aodhan O'Riordan.
Members of Dublin City council's Central area policing committee were briefed on supervised injection centres.
They were shown how similar rooms work in Sydney and how that model could be incorporated here.
Former Lord Mayor Christy Burke says he's in two minds about them:
"Would a mobile bus unit, a properly kitted out one, decked out, maybe you run on a pilot scheme. Or if this was to be run on a pilot scheme, just to see how the figures come".
Local TD Maureen O'Sullivan understood why they were needed but was concern:
"I would hope that it doesn't detract from the optimum aim which is people to go into recovery".
Tony Duffin from the Ana Liffey drug project said they won't replace proper rehab but the problem is growing in the city:
"We think there's around 400 individuals in any given month that would be injecting in Dublin City Centre, but that is a conservative estimate, it could be much higher".
The heads of the bill to allow the centres was approved before Christmas and it's hoped it'll be passed by the Dail in the Summer.
