PHARMACEUTICAL DRUG

A psychoactive drug or psychotropic drug is a chemical substance that changes nervous system function and results in alterations in perception, mood, consciousness, cognition, or behavior.

Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis.

These substances may be used:

• medically
• recreationally
• to purposefully improve performance or alter one's consciousness

• for research.

Some categories of psychoactive drugs, can have therapeutic value, as medications used to treat neuropsychiatric disorders, such as antidepressants, anxiolytics, antipsychotics, and stimulant medications. Some psychoactive substances may be used in the detoxification and rehabilitation programs for persons dependent on or addicted to other psychoactive drugs
