Researchers at Harvard University have found an interesting new recipe to significantly handicap children throughout their lives – smoke around them regularly. The new research examined over 50,000 children and concluded that ones exposed to significant secondhand smoke were 50 percent more likely to have an attention deficit, learning disorder, or behavioral problem. Although the new study is correlational only and does not prove causation, other research suggests that nicotine plays a role at least in attention disorders. The researchers estimate that attention, learning, and behavior problems in over 250,000 U.S. children could be prevented each year by eliminating smoke exposure.
