One major criticism of social and psychological explanations of smoking in schizophrenia is that most studies have failed to include personal perspectives of patients with schizophrenia. Studies including personal perspectives find that people with schizophrenia generally start smoking for the same reasons as the general population, including social pressures and cultural and socioeconomic factors. People with schizophrenia who are current smokers also cite similar reasons for smoking as people without schizophrenia, primarily relaxation, force of habit, and settling nerves.
