Intoxication due to multiple specified psychoactive substances

Description

Intoxication due to multiple specified psychoactive substances is a clinically significant transient condition that develops during or shortly after the consumption of multiple specified substances or medications that is characterised by disturbances in consciousness, cognition, perception, affect, behaviour, or coordination. These disturbances are caused by the known pharmacological effects of the multiple specified psychoactive substances and their intensity is closely related to the amount of the substances consumed. They are time-limited and abate as the multiple specified substances are cleared from the body.
