Anyone with an interest in the effects of organic chemical compounds on the human body and especially the psychological effects of psychoactive chemicals on the human brain and mind will find no finer repository of reliable and accurate information. Over the many years I have had cause to refer to the annals of Erowid I have seen this priceless source of information grow to encompass all that is relative in the chemical/human/psyche relationship and it's enlightening avenues have given me many new directions for research, experimentation and diagnosis.
Especially useful are the personal testimonies and experiences of users of any given compound. These user experiences have proved so usefull and insightfull over the years that scientific methodology in the practice of analytical psychology has been improved, redesigned and streamlined as a result of the wealth of freely accessable true and honest testimony built up by Erowid. It is a unique and valuable resource.
