How is smoking related to schizophrenia? 

Tobacco smoking is very common among people with schizophrenia, who often show particularly heavy usage. This poses considerable health risks, may interfere with antipsychotic medications and may place a financial burden on the individual. Heavy cigarette use may contribute to the increased mortality and reduced life expectancy reported within the schizophrenia population.

What is the evidence for smoking?

Moderate to low quality evidence suggests people with schizophrenia have higher rates of smoking and lower rates of smoking cessation than the general population, including people with other mental disorders. People with first-episode psychosis, and people exhibiting risk for psychosis symptoms, also show higher rates of smoking. There is a medium-sized increased risk of psychotic disorders and an earlier age of psychosis onset in smokers compared to non-smokers.
