Substances/Content

A psychoactive drug, psychopharmaceutical, or psychotropic is a chemical substance that crosses the blood–brain barrier and acts primarily upon the central nervous system where it affects brain function, resulting in alterations in perception, mood, consciousness, cognition, and behavior. These substances may be used recreationally, to purposefully alter one's consciousness, or as entheogens, for ritual, spiritual, or shamanic purposes, as a tool for studying or augmenting the mind. Many psychoactive drugs have therapeutic utility, e.g., as anesthetics, analgesics, or for the treatment of psychiatric disorders.

This portal attempts to categorize and provide relevant, accurate and unbiased information regarding psychoactive substances. It focuses not just on detailing the chemistry, pharmacology, toxicity and harm potential but also sets out to describe and document in an extremely high level of detail the subjective effects which may occur under their influence. This is done by following a standardized system of organization with descriptions and terminologies that can be found within the subjective effects index.
