closer to a cure for smokers?

It seems that damage to a certain area of the brain- near the ear, to be more precise- could remove instantly and entirely addiction to smoking...says scientists. So now brain injury is a possible solution to addiction...sounds freaky and scary to booth. Scientists, it seems, think this part of the brain has no real function! For now at least. And further add that its removal, for instance, doesn´t have any negative effects on say..appetite etc- I wonder why this part of the brain is only being considered for smoking adictions..wonder what would be the effect on other addictions as well......All the same, it still seems to be a crazy, drastic idea... imagine eliminating part of the brains of our already brainles society!
