The Multidisciplinary Association for Psychedelic Studies is an advocacy group which promotes the use of MDMA, hallucinogen/psychedelics and cannabis. Their views are usually scientifically informed and thus criticism of existing research can be of interest. Of significant utility to those without access to a research library, they maintain a database of the scientific literature, including full text PDFs in many cases.
