Abstract title: DIMS, 30 years of experience with consultation

The Dutch drug checking service Drugs Information and Monitoring System (DIMS) has been running for 30 years. Over the years the basics of the system have remained pretty much the same, but of course there are some changes. One of them is the approach to the consultation with the visitors. Research, discussions and insights from employees changed the subjects and the approach of the consultation. How did it evolve over the years and what did it evolve into? Another change is the number of visitors, which has increased dramatically over the last few years. Which leads to friction between helping as many people as possible and informing the visitors to the best of our abilities.
