The fact that you can alter your own consciousness to such wildly varying degrees by way of ingesting chemical substances suggests that it's a physical and electrochemical phenomenon, and nothing to do with a "soul" or suchlike, IMO.
If your consciousness truly was tied to a "soul", then surely some otherwise nice people wouldn't become absolute tools when drunk?
Your not altering your conciousness though, but altering your perception and how your brain reacts to stimuli.
