That's why I love ketamine, because of the euphoria.
But it's euphoria of a different level to say traditional drugs such as opiates and stimulants. In other word's it's not so much a bodily or emotional euphoria, but it's source originates in the higher mind and imagination. Much like psychedelics, hence the very reason I believe why it's classed as a psychedelic. As it dissolves much of lower heavier ego, such as fear and awareness of bodily functions to make way for a very deep and immersed spiritual experience. Words soon fail to capture and express such a euphoria, it really is "out of this world."
