Bydd Llywodraeth Cymru yn penderfynu sut yn union i ddyrannu'r £4m ar ôl cael cyngor gan banel annibynnol. Mae'n bosibl y gallai gynnwys ehangu'r canolfannau triniaeth yn y gymuned sydd eisoes yn bodoli, hyfforddiant ychwanegol ar gyfer staff meddygol i drin mwy o amrywiaeth o gleifion a gweithgareddau eraill i gynnal gwasanaethau cynaliadwy.
Decisions about exactly how the £4m will be allocated will be taken by the Welsh Government following advice from an independent panel and could potentially include the expansion of existing community based treatment centres, additional training for medical staff to treat a greater range of patients and other activities to support sustainable services.
