Here's the daily "why you should not smoke" tidbit:

Women who smoke in pregnancy may raise the risk of their child displaying anti-social behaviour, researchers say.

There was a "small but significant" link between maternal smoking and both unruly behaviour and attention deficit hyperactivity disorder, they said.

The average symptom scores for both increased with the number of cigarettes the mother had smoked while pregnant, the study of 1,896 twins found.

The Institute of Psychiatry work is in the British Journal of Psychiatry.
