The various types of evidence that may be used in responding to drug problems differ in their strengths and weaknesses and in the information they can provide. Drug-related problems are multifaceted and require not only medical, but also socioeconomic and educational interventions. As a result, it is often necessary to integrate evidence from a range of disciplines and types of study, using both quantitative and qualitative research methods.
