Can eating soap hurt you?

I think you want to move this question to health, but my answer is that the acid in your stomach chemically changes the soap into something else anyway. Soap is a base (alkaline) and acids would neutralize it. It's like when you mix vinegar and baking soda. So now you have another substance altogether. But you could conceivably inject soap into your veins by means of a needle. This would bypass the acids in your stomach. If this had any medical benefit, doctors would be doing it! Obviously they aren't. Maybe you shouldn't mention that docs don't hook people up to a soap IV, though, because the next thing  you know he will kill himself by shooting up with soap!

NO!.  his digestive system won't like that.  and it'll do zero for his blood system.  fortunately, the most likely result is that he'll get sick
