I think so because there is the dependence on a glorious hereafter and if you are dead you wouldn't get to know if it were true or not so it seems a bit like having money in the bank when you die without a will.

Yes. Just like crack rock and other drugs, religion can be addictive and make you feel good. However, long term use of religion and/or crack rock is not good for you. Lol

It's more like bath salts or Crystal meth it gets hold it becomes everything and it makes you do a bunch of crazy shit

Its true - people will search for truth until they think they've found it. Belief in God and an eternal reward gives them peace.
