Oh, I imagine it would work all right. Probably a very fast route to intoxication. I would think it would burn like crazy.
Yeah - sounds like an easy way to over dose.
I recall some show where the family was stuck out somewhere and lost. Only bad water around, no way to purify it. The dad must have had some training - and they gave themselves “enemas” or whatever. The water was absorbed through the tissues and filtered that way. It kept them alive for quite awhile as I recall.
