Supportive and Specialized Care

Taking psychedelics can result in overwhelming and uncomfortable experiences, more likely with high doses, amongst first-time users, and without adequate preparation or setting. Psychedelic harm reduction includes a variety of methods to help prevent and transform difficult experiences while in a non-ordinary state of consciousness.
