This year we are very pleased to extend an invitation to you from Glasgow, to join us for our fifteenth national conference. The theme for the conference focuses on the need for all practitioners and services to work together, influenced by evidence, values, experience and the voice of people with drug and alcohol problems. We will also consider the importance of the clinical voice in positively influencing drug policy. Over the course of the two days there will be plenty of opportunity for discussion, debate and knowledge-sharing with your peers, user advocates and leading professionals.
