It is a mental disorder characterized by the presence of psychotic symptoms, such as delusions and hallucinations, which are caused by the use of psychoactive substances.
The main cause is the abuse of drugs such as cocaine, methamphetamine, cannabis and hallucinogens.
Symptoms include hearing, seeing, feeling, smelling, tasting things that do not exist (hallucinations), believing things that are not true (delusions), disorganized thinking and behavior, and lack of motivation and emotion.
Diagnosis is based on the presence of symptoms caused by psychoactive substance use, ruling out other psychiatric disorders such as schizophrenia.
Treatment includes substance detoxification, psychotherapy and anxiolytic or antipsychotic medications.
