High-functioning autism linked to prenatal smoking in study

Smoking while pregnant could increase a child's risk of high-functioning autism, according to a new study in the Journal of Environmental Health Perspectives.

The study found the risk was slight and there was no association between maternal smoking and more severe forms of autism.

Experts say their findings suggests that, although autism spectrum disorders share many of the same symptoms, subtypes of the disorder likely have many different genetic and environmental causes that vary from person to person.
