"Behavior problems in children have increased from 7 to 18 percent over the last 20 years for reasons that are poorly understood. Exposure to environmental tobacco smoke is increasingly recognized as a risk factor for child behavior problems."
That's odd, the percentage of adult smokers went down from 30.1 to 20.9 from 1987 to 2006.
Blaming an increase in behavior problems over that time period on smoking doesn't make any sense.

While the percentage of adult smokers went down, the availability of junk TV aimed at kids went up, as did the hours children spent in day care. We won't even mention the number of marriages that ended in divorce.
But no, obviously the increase in behavior problems is due to tobacco.
