Dr. Des Crowley:

We have the data. We have the prevalence studies and so we know how many people are using. We know the population profile. We also have the HRB data on people presenting for treatment and what they are presenting for. There is a framework against which we can match. We also have good evidence on evidence-based treatments for each of the different types of addictions. There is a great deal of information that can be put into a framework in terms of delivery of services.
