I'm not a medical expert but clearly something is wrong here. I believe the reason for the increase in these prescriptions is a combination of not enough parental attention, the need to control naturally energetic children, and a drug industry that is only too ready to provide a solution. I'm sure these drugs have there place, but the numbers are so starkly wacky that this screams inappropriate prescribing.
Kids have lots of energy, but what they need is exercise, attention, and avenues for self-expression. Their excess energy that could be "controlled" in much healthier, more creative ways.
I find it ironic and sad that the arts are being erased from many public school curricula and you even hear reports of schools eliminating outside activity in the playground because of crime and liability issues. So, we silence the music, silence the recess bells of play, and provide a pill that fogs the mind... it's beyond sad, this really makes me angry.
I am not a futurist, but I am a social observer so I'm going to make a prediction based on my observations. The chickens will someday come home to roost. These drugged children will grow up and will become anti-doctor, and anti-prescription drugs, and in a very angry and active way.
