Psychedelic Science Review (PSR) was founded in 2018 by a small group of scientists committed to improving the quality of and access to scientific information about psychedelics. Concerned about the dearth of accessible and reliable scientific information about psychedelics, widespread misinformation, and poor analysis and conclusions drawn from otherwise high-quality research, our team set out on a mission to address these concerns. In 2019, we launched PsychedelicReview.com, a website free for all to access. At PsychedelicReview.com, we discuss scientific research and knowledge about psychedelics, from chemistry to psychology. Our science writers break down complex topics, offering context and connecting important concepts in the literature to familiar examples. PsychedelicReview.com also offers background information about psychedelic compounds, an ever-changing history of events surrounding psychedelics, and the organizations and people involved in progressing this resurgent field. Psychedelic Science Review provides an exclusively scientific perspective on psychedelics. We are not proponents or opponents of political or social change, nor do we offer moral commentary. While there is a place for those voices, our goal is to offer factual information on the basis of scientific relevance.
