There being a God is the ultimate excuse to avoid personal responsibility for one's actions in life. And one of the consequences is as you say wee; better to remain ingnorant, yet secure, than aware and free. It's almost like we're all living in golden cages, beautifully made and looking, and so we stay there. We have the key, but refuse to leave the cage. It's secure, and to leave would be to go naked with nobody to look after you.
However secure the cage feels, there is no freedom in a cage. And those that never leave the cage have wasted their one stab at life.
Taking certain drugs demands that the user open the cage, throw the key away and throw the cage away, and simply live outside. People can do the same thing without drugs, but it just takes much longer.
