About

Effect Index exists to serve as a dedicated resource for formalised documentation of the vast number of distinct subjective states which may occur under the influence of hallucinogens. It strives to showcase the world's first truly comprehensive subjective effect index which is capable of describing the wide variety of potential hallucinogenic experiences. This is done so in an easily readable format that contains not just descriptions but also informed analysis with image and video replications.

This site was initially founded as a side project on June 30th 2017 by Josie Kins, the creator of PsychonautWiki, DisregardEverythingISay, and the subjective effect index. It provides a dedicated platform for content that has been in constant development for the past six years within other projects. This was done in the hopes of further spreading the site's documentation so that eventually it may serve as a universal terminology set which gives people the language to fully discuss and describe experiences that were previously considered ineffable.

Effect Index hopes to pioneer this concept of formalised subjective effect documentation because demystifying the experience has a huge potential to allow hallucinogen usage to become culturally acceptable, better understood, and more easily studied.
