[Chemicals in tobacco may help trigger serious mental illnesses
such as schizophrenia, a study suggests.
New research shows that smoking can triple the
chances of developing psychosis.
Previously the fact that people with psychotic mental illnesses
are more likely to smoke has been put down to non-causal factors,
such as obtaining relief from distress or self-medication.
But now scientists believe something in tobacco might actually
be responsible, alongside genetic and environmental influences.]
