 We have to emphasize that the NBS is a problem in which we have to address as professionals, but in doing that we need each other. We have to do it, we have to collaborate with each other. It's not only the clinical relevance of addressing NBS, but it's also the social context where we are performing that in. Thus we have to work in multi-dimensional perspective with clinicians, with social workers, with sexual health providers, but also in the first and in the specialized line. So I run a club drug clinic, a clinic specifically for people who use these new substances. And we set the clinic up because we had such demand actually from other parts of the health front line, from A&E departments, from sexual health clinics, from mental health services, saying that they had patients that didn't want to come to traditional drug services. And it's time for drug services now to widen their front doors, to open the doors and their services, so that these new users can access treatment. To do that they need to develop their clinical competence and the cultural competence to meet the needs of these new users.
