I’m old enough to remember getting popcorn at the movie with REAL butter, not that synthetic crap they have today.
Sometimes these studies are not "true", i.e., it takes 1000 times the exposure to cause anything "substantial" to happen.
So the question should be....If he worked someplace else, would his condition have gotten worse. It's a yes or no...There is no maybe.
Wouldn't wish it on anyone...but...
If it can be proven that the popcorn did this and the guy is really needing a lung transplant, I don’t think I have a problem with this. Big “ifs” though.
I know this case. The guy had popcorn at work every day. He would open each bag hot out of the microwave and breathe in the fumes. They couldn’t diagnose the turd for quite a while until he admitted to smelling the popcorn for YEARS! 30 M! Ridiculous!
Juries like this cause increased prices. The jury cannot prove the chemical contributed in any way to his demise. He took a job at the plant after he already knew of his lung condition.
