Psychedelic Drugs: A Study of Drug-Induced Experiences Obtained by Illegal Drug Users in Relation to Stanislav Grof's Model of Altered States of Consciousness

Abstract

The purpose of this study was to provide information about experiences obtained by illegal drug users and evaluate if these are consistent with Stanislav Grof's expanded model of the human unconscious. Sixteen anonymous former drug users answered a questionnaire about use, experiences, circumstances, and influences of their life. All of them have had some experiences similar to Grof's descriptions. Transpersonal experiences were more reported by those who used to be “heavy” users. Such experiences were also more likely to be reported by those who described themselves as spiritual seekers and by those who made some form of ritual or mental preparation part of their experience. This study also provides general information about Grof's model and some about psychedelic research worldwide.
