Mobile phone ban for Children under 16yrs in Karnataka

Watched the debate on NDTV last night, it doesn't make sense to many giving health as a reason for children under 16yrs. There are so many other real health hazards like cigarettes, pan parag, pan and the worst liquors which causes more causality and problems to themselves and the public. Why didn't the Govt. think about this? Mobile isn't as dangerous to be banned, children use it mostly to be in touch with their friends and family. If radiations is the reason for the ban, why cant they think if head sets can be a better options than banning. They should stop selling liquor which in many states are adulterated as well.
Using mobile phones during or inside the class is unacceptable but this should not stop them from using after or in case of emergency.
We all studied without mobile phones, but those years were different. Ladies never or rarely ventured out after 5p.m. Now there are ladies night out also so you can see the change in freedom. Along with any kind of freedom, danger or security or sincerity also take twist. Had our parents had the money, time and Technology like now, we would have carried mobiles. So comparisons are a time pass. Infact it we, educated parents who are giving mobile phones to our Children mostly to stay in touch - that extra confidence of being close to your children.
My view is, banning mobile phones for children under 16yrs is not done with the reason quoted over the media (Health), maybe there is more to this. Liquors or Alcohol cause more damages in day to day life and in many cases results in fatality and brutality, why isn't this banned?
