Signs and symptoms
The symptoms of stimulant psychosis may vary slightly depending on the drug ingested but generally include the symptoms of organic psychosis including hallucinations, delusions, thought disorder, and, in extreme cases, catatonia.

These additional symptoms may include aggression, arrhythmia, dilated pupils, diarrhea, hypertension, hyperthermia, nausea, rapid breathing, restlessness, seizures, sleep deprivation, tremor, and vomiting""
