Mental disorder characterised by the presence of psychotic symptomatology, such as delirium and hallucinations, caused by the consumption of psychoactive substances.
Its main cause is drug abuse such as cocaine, methamphetamines, weed and hallucinatory drugs.
Symptoms include seeing, hearing, feeling, smelling, tasting things that don't exist (hallucinations), believe in things that aren't real (delusion), disorganised thought and behaviour, and a lack of emotion and motivation.
The diagnosis is done based on the presence of psychoactive drug consumption symptoms, and ruling out other psychiatric disorders such as schizophrenia.
Treatment includes a substance detox, psychotherapy and anxiolytics or anti-psychotic medication.
