What sort of issues surround cell phones and kids?

Driving. There is no proven harm from cell phone use. The major health risk is probably teenagers who use cell phones while driving. Foolish for the obvious reason of increased risk of mva.
Agree but... Considerable speculation has been made regarding electromagnetic energy and radiation exposure so close to the brain. However a causal effect with brain tumors has been unsubstantiated. Best to use bluetooth technology any way!
