I'm not so sure anyone would be able to consume enough of it to actually get ill (long-term). Basically, after the first swig, most people's gag reflex would kick in high gear and they'd simply puke it up. But you never know.
You might have to pay to have their stomach pumped.
I remember many years ago, daring an acquaintance of mine to drink a "big gulp" sized cup of puddle water from the Burger King parking lot. Of course cars had been driving through it, etc. It was filthy. The guy must have been mentally ill, because he actually did it for a mere $60. He didn't die, but he did get violently ill a few hours later I recall. I felt terrible about it afterwards, but he was stupid enough to do it.
