Kids love sweets, so it's not unusual for them to see a brownie or a cookie and grab it. But some kids are unknowingly eating sweets laced with marijuana. Dr. George Wang treats kids at the emergency room at Children’s Hospital Colorado. He's also with the University of Colorado School of Medicine. A couple of years ago, he began seeing kids who were having trouble breathing and walking. Diagnosis: they had marijuana in their systems. So, Wang and his colleagues did a study to see how often it was happening. The results are in the latest edition of the pediatric journal of the American Medical Association. Dr. Wang spoke with Ryan Warner.
