Smokers may be at greater risk of depression and schizophrenia, study finds

Scientists found a link between smoking tobacco and mental illness.

(CNN)People who smoke tobacco may be at a higher risk of developing depression and schizophrenia, according to a new study.

A team of researchers led by scientists from the University of Bristol in the UK has added weight to growing evidence that smoking can have a negative effect on mental health.
