IntroductionThe use of psychostimulants, such as amphetamines and cocaine in psychotic patients is 4 times more frequent than non-psychotic ones. It is believed that people with psychosis may use substances as a self-treatment for negative symptoms. However, early onset of substance use disorder can develop psychotic and/or negative symptoms, leading to confusion between primary or secondary psychosis.MethodSystematic review of the literature in English (PubMed) and patient's clinical record.

During this period, he has been treated successfully with aripiprazol depot once monthly. His evolution has been positive, it has disappeared psychotic symptoms and paranoia, and after discharge he has managed to remain abstinent to psychostimulants.ConclusionsAdequate characterization of patients with psychotic symptoms and substance abuse is essential to determine whether the psychotic disorder is associated with primary or induced TUS.
