My view is that a religion is any practice, behavior or action which leads an individual to a spiritual experience.
Therefore on tonights cencus form I have stated my religion to be 'entheogenist'. As this is the way that I most often experience a spiritual connection. Nature is also prominent however classical psychedelics are an integral part of the experience.
Do you think the term 'entheogenist' is too broad as could include cannabis or even alcohol?
Is your definition of religion different?
