Umm. not really.
I don't think anyone would argue that people who go to Church everyday are under the same "spell" as drugs, and they sure as hell wont go through withdrawal for missing Church.
I think anytime you put your faith into something all the way without questioning the outcomes, to the point that its intefering in all areas of your life or causing you to harm other people, those sets of beliefs need to be questioned. So, in a sense, a violent fundamentalist might be closer to an "addict"... but someone who chooses to be part of a religion is no way more "blind" then someone who believes in capitalism or any other large scale social organizing.
Addiction is harmful, but someone who is super religious can still lead a healthy meaningful life.
