My understanding is that each alone can burden the liver, but when combined is when they're dangerous. Apparently it has to do with the fact that the liver is already under stress from dealing with the alcohol and it doesn't take much acetomenphen to do the damage. It happened to a girl in the town we used to live in; it was all over the news there. She didn't die but sustained liver damage.

That's what I was trying to get said, but you were clearer.
