ARe religions in general really the manifestations of an addiction problem.?

You see so many posts about feel the love, I feel the spirit etc with posters from any religion. It is known that these types of activities stimulate the limbic region of the brain (beta endorphins etc) giving the person a feeling of oneness etc. People experiment with drugs, alcohol, etc for precisely the same benefit. From this perspective aren't most religions really a gathering of like minded beta endorphin addicts?
