A planning application for the country's first drug injection centre will be made before the end of the month according to Merchants Quay Ireland.
MQI won the tender six months ago to operate the facility in a basement area of its premises on Merchant's Quay.
The organisation's outgoing CEO Tony Geoghegan said the application had been delayed by building design issues but the application will now be lodged before October.
Mr Geoghegan was speaking at the launch of MQI's annual report which showed that the organisation helped 10,417 people with addiction, homeless and mental health issues last year.
The MQI Night Cafe provided mats 19,368 times to nearly 2,000 rough sleepers.
There was also detox and rehab treatment for 107 individuals.
Mr Geoghegan who is stepping down after more than 30 years working in drug treatment, says he is "optimistic" that drug addiction in Dublin will be reduced.
He says he believes that the economic recovery and better treatment services including the drug injection room will help.
The numbers on methadone have increased from around 1,000 in the early 1990s to around 10,000 now.
But he says this is a societal problem being experienced by many countries.
He says the issue in Ireland had been exacerbated by the housing crisis.
