why anyone would willingly ingest that stuff is beyond me.... i've tasted my fair share of bong water... none willingly of course.... it actually still sits atop of my most disgusting things list.... even after working on a 20 something year old car that had set up for 3+ years.... why is that relevant? well anyone who's undertook a similar task can assure you, there are some pretty disgusting tasting things underneath... a car that old and set up is just caked with crap, every turn of a bolt sends miniture clouds of the shit out.... it's not an uncommmon occurance for it to find it's way in your mouth.
