What are diagnostic criteria for acute intoxication?

G1. There must be clear evidence of recent use of a psychoactive substance (or substances) at sufficiently high dose levels to be consistent with intoxication. G2. There must be symptoms or signs of intoxication compatible with the known actions of the particular substance (or substances), and of sufficient severity to produce disturbances in the level of consciousness, cognition, perception, affect, or behavior that are of clinical importance. G3. The symptoms or signs present cannot be accounted for by a medical disorder unrelated to substance use, and are not better accounted for by another mental or behavioral disorder.
