Try and take away a tween's cell phone and see what happens. The results won't be pretty.
That's the idea behind the Colorado group, Parents Against Underage Smartphones.
They want to ban selling phones to kids under 13. If the measure passes, it'd be the first in the nation.
Right now, Colorado officials have cleared the way for a proposed ballot measure.
It's up to the group to get about 300,000 voter signatures for the measure to make the 2018 ballot.

UNITED STATES - DECEMBER 09: The Motorola company was founded by Paul V Galvin as the Galvin Manufacturing Corporation, in Chicago, Illinois, in 1928. In the 1930s the company began promoting portable car radios under the brand name ï¿½Motorolaï¿½ (a word suggesting sound in motion), and the company name was changed to Motorola Inc in 1947. By the end of the 1980s, Motorola had become the biggest worldwide supplier of cellular telephones. When it was launched in 1996, the pocket-sized StarTAC, at just 93g (3.1 ounces), was the worldï¿½s smallest phone and the first to operate continuously with dual detachable batteries. This example was manufactured by Motorola Inc in the United States. (Photo by SSPL/Getty Images)
UNITED KINGDOM - JUNE 20: Taking mobile phones apart by hand and sorting the pieces for recycling is expensive. This phone was designed by Joseph Chiodo, a researcher at Brunel University in Surrey, to 'recycle' itself. It is made from special metals and plastics which have 'memories' of their original shape. When heated up, they lose their current form and revert to the shape they remember: different parts are triggered to change shape at different temperatures. The phone then ï¿½popsï¿½ apart, ready for recycling. Pieces can be picked out for reuse and the parts containing toxins can be separated. (Photo by SSPL/Getty Images)

The initiative would cause retailers to ask who would be the primary user of the phone and file monthly reports to make sure kids under 13 are not texting away.
They'd get a warning for the first strike but could be fined anywhere from $500 to $20,000 if they do it again, according to a local Fox-TV station in Denver.
The founder of the group is a doctor and says he thought of the measure after seeing his own kids go through psychological changes after locking themselves in their rooms to look at a screen all day.
Opponents say it's government overreach and should really be a family matter.
The American Academy of Pediatrics recommends limiting screen time to no more than an hour a day until the child is six years old.
Then, parents can set consistent time limits. Who is a six-year-old even calling anyway?!
