The States of Consciousness Research Team at Johns Hopkins University is conducting a research study on psychedelic experiences that alter beliefs about death and dying. The study is open to anyone who has had such an experience involving the use of a classic psychedelic such as LSD, psilocybin, mescaline, or DMT. To participate in the study, complete the online Psychedelic Death and Dying Survey. The survey is anonymous and takes about 30 minutes to complete.
