As part of the last Drug and Alcohol Strategy, a review into the feasibility of such a facility was carried out.
There was an 'initial indication' of a clinical need but cost implications and a lack of funding has held back any progress.
Drug and Alcohol Strategy coordinator Andrea Nightingale, pictured, said although there were no immediate plans to introduce an on-island centre, the Home Department was now looking at introducing a day programme for those returning from off-island rehabilitation, and other addicts.
That would act as a stepping stone towards an on-island facility, she said.
'What we are looking to do is a day programme that all drug and alcohol users can access.
'That would be our first step to then looking at residential rehabilitation.'
