The Report on the Situation of Mental Health and Psychoactive Substance Use compiles relevant data on substance use and mental health, with the purpose of providing interested persons and decision makers from the public, private and social sectors who join efforts to prevent and provide care in the area of mental health and addictions with reliable and objective information on the current landscape. The report is also a clear example of the exercise of democratising public information on mental health and addictions, which cannot and must not belong to just a few.
