This whole argument is the wrong way around.
You're an addict if you can't refrain from doing something. That doesn't mean that anyone that does something does so through addiction.
Someone who couldn't refrain from reading a newspaper or eating a Mars Bar for half an hour would be an addict and would fall within any reasonable definition of mental illness.
Well, exactly.
Someone who couldn't refrain from drinking for half an hour would be the same. However, this does not apply to someone who would like to have a drink on the tube.
