Introduction: Diagnostic certainty is difficult in the early stages of psychotic disorders, and it becomes more complicated if at the same time alcohol or drugs get consumed. There is a bilateral association between substance use and psychotic symptoms. Thus, this study was aimed to evaluate the lifespan diagnosis in patients with substance-induced psychosis admitted to psychiatric wards of Imam Hussein Hospital in Tehran 2015.Method: Through an accessible sampling method, this cross-sectional study was conducted on 90 patients diagnosed with substance-induced psychosis in the psychiatric wards of Imam Hussein Hospital in Tehran. The data were analyzed through frequency descriptive statistics and charts, and by logistic regression using SPSS23 software. Results: In patients with substance-induced psychosis, the results showed that bipolar disorder with psychotic symptoms was the most common disorder (48.9%), followed by schizoaffective (36.7%) disorder, schizophrenia (22.2%), personality disorders (16.6%) (Antisocial, 5.5%; borderline (BPD), 11.1%), adult attention-deficit/hyperactivity disorder (ADHD) (3.3%), obsessive-compulsive disorder (OCD) (4.4%), and post-traumatic stress disorder (PTSD) (1.1%). Logistic regression results showed that the patients' age and family history of psychotic disorders could significantly predict the transition to the spectrum of primary psychotic disorders.Conclusion: In psychotic patients or those with primary psychosis, the simultaneous consumption of several substances may indicate a further aggravation of the disease and accelerate the transition of their diagnosis. The transition of the diagnosis of substance-induced psychosis into primary schizophrenia should be considered in the treatment and administration of the drugs
