Smoking During Pregnancy=Psychotic Children?

Many studies have shown that smoking throughout your pregnancy can be harmful to the baby, but this study shows that smoking may cause your child to develope psychotic symptoms in their teenage years. Four British Universities interviewed 6,356 12 year old kids in search for these psychotic symptoms. 19% of the kid's who showed "some" symptoms had mothers who smoked during the pregnancy. 11% (734 of the total group) had definite symptoms of psychosis, and had a mother who smoked often throughout her pregnancy. Alcohol also has the same affect on the child. The reason for the link is not completely known but they suspect that exposure to tobacco (and alcohol) in the womb has great affect on the child's brain function like impulsivity, attention, or cognition.
