Effects/Content

The subjective effect index is designed to serve as a comprehensive catalog and reference for the range of subjective effects that are reported to occur under the influence of psychoactive substances and other psychonautic techniques.

The effects listed here are accompanied by individual descriptions that detail how it feels to experience them. They are written in a formal and standardized writing style based on phenomenological observation that seeks to avoid the use of flowery metaphors or analogy, instead striving to use language that is as simple and understandable as possible. This is done in the hope that they will eventually serve as a universal terminology set that enables people to better communicate and share experiences that are by nature difficult to convey.

The effects are separated into over 200 components which are organized into categories based on which sense they affect and their features. Many of these are further broken down into leveling systems, subcomponents, and style variations that can occur across different substances. Detailed replications in the form of image and video examples have been included wherever possible to supplement the text descriptions.

The content within this index is based on the collective experiences of our contributors.
