Maine might force cellphones to have cancer warning

Cellphones have yet to be confirmed as to whether their use is able to cause cancer, but a Maine legislator might just have it that the state becomes the first in the country to carry warnings that they are able to cause brain cancer, even though there is no concrete evidence just yet that such a thing happens. Selected countries do require cellphones to carry such warnings, although there are no US states at the moment that require them to do so at the moment. Even if such a risk were to be proven true, would that make you talk less on your handset, or would it see a push in Bluetooth headset sales?
