A '''psychoactive substance''' is a chemical substance—other than a nutrient or essential dietary ingredient—that alters brain function to produce temporary changes in sensation, perception, mood, consciousness, cognition, and behavior.

Psychoactive substances have been used by humans for a variety of purposes since recorded history. For example, they ~~can~~ be ~~taken recreationally~~ for their ~~pleasurable or [[euphoria|~~euphoric]] effects and novelty value, as [[entheogens]] for ritual or spiritual purposes, or as scientific research ~~tools~~ for studying the brain and mind. The latter two have particular relevance for practitioners of [[psychonautics]]. Many psychoactive substances have established therapeutic utility and are used in routine medical practice (e.g. [[dissociatives|anesthetics]], [[pain relief|analgesics]], [[anxiety suppression|anxiolytics]], [[antidepressants]], etc.).

Psychoactive substances have been used by humans for a variety of purposes since recorded history. For example, they may be used as medicine, as recreational substances for their euphoric effects and novelty value, as [[entheogens]] for ritual or spiritual purposes, or as scientific research probes for studying the brain and mind. The latter two have particular relevance for practitioners of [[psychonautics]].

The '''''Psychoactive Substance Index''''' ('''PSI''') is designed to catalog and provide relevant, accurate, and unbiased information for any and all mind-altering substances known to humankind, with special ~~attention given to~~ those ~~that may have utility~~ as mind-expanding tools. The individual articles detail not just the history, chemistry, pharmacology, toxicity, and legality of each substance, but also its subjective effects (i.e. phenomenology). This is ~~done~~ in accordance with a standardized system of definitions and terminologies ~~found~~ in the [[subjective effect index|'''''Subjective Effect Index''''']] ('''SEI''').
