Hi CharlieRN Thankyou for your observations. As we do not have a precedent, in the UK, for nurse prescribing in the substance abuse field I do need the views of you folks that are already engaged in it. The experience in the UK is that by far the majority of dependent opiate users have a recreational aetilogy, iatrogenic users are the exception. The "English" model is recommending early engagement, intervention and replacement therapy based around the "risk reduction" model... an ethical minefield. The replacement therapy commonly used in the UK is Methadone, and very occassionally Diamorphine Hydrochloride. The increasing numbers of presenting opiate users and saturation of health service resources, including the increasing shortage of specialist medical staff, has brought about the discussion in nurse prescribing. The reality is that nurse prescribing will happen, my review aims to bring this about safely to the benefit of the patients and to my nursing colleagues. In your experience, do you see any distinct advantages or disadvantages to yourself or to your clients for nurses to prescribe within the substance abuse field? Thanks again for replying Alan
