To ask the Secretary of State for Health if he will commission research into opioid substitution therapy. 
The National Treatment Agency for Substance Misuse (NTA) is aware that there is well-developed research evidence into the use of opioid substitution therapy—particularly into the effectiveness of oral methadone maintenance treatment. An important part of the NTA role is to support high quality evidence based practice. It is recognised that some findings from the evidence base are not fully implemented and the NTA has built a variety of mechanisms to support the implementation of key research findings into to practice, including briefings, training, commissioning guidance and increasingly performance management systems. The NTA is also working with the Department of Health to develop dissemination of the findings of its current drug treatment research programme. The NTA has recently published a briefing on the advice of its expert group on prescribing, which includes a brief review of the evidence base for opioid treatment.Copies have been placed in the Library.The NTA will commission new research in line with the outcome of its current priority setting exercise that is awaiting approval by the NTA Board in March. Research bodies will be invited to submit tenders in line with these priorities.
