A recent research by health professionals at Finland shows that smoking during pregnancy increases a baby's (foetus') chances pf developing a kind of mental disorder termed schizophrenia.
The scientists who analysed data on 1,000 schizophrenia patients and matched their birth and health records with those of non-affected "control" individuals showed that a fifth of mothers of schizophrenia patients were found to have smoked heavily while pregnant, compared with 14.7% of mothers of controls.
Senior researcher Professor Alan Brown, from the University of Columbia in New York City, said: "To our knowledge, this is the first biomarker-based study to show a relationship between fetal nicotine exposure and schizophrenia."

Schizophrenia is a chronic and severe mental disorder that affects how a person thinks, feels, and behaves. People with schizophrenia may seem like they have lost touch with reality. Although schizophrenia is not as common as other mental disorders, the symptoms can be very disabling.
