mind is put into an android? I can't remember the name of this book. It's a teen book about a society that scans people's minds into a chip and then inserts it into androids so the people won't die.

She escapes with a boy who introduces her to, I guess it would be like drugs, they stick metal into their android arms and they get a kick out of it. I can't remember what this book is called, does anyone know?
