Shortly after you posted this article, I noticed a news item about a hotel in Berkeley that had to be evacuated and hazmat called in because someone committed suicide by chemical and I was thinking, "Did someone read this article and get the idea to...?" Seemed crazy, but copycats often do crazy things.

Turns out, it was a different chemical (sodium azide). The woman was in her 80's. Probably no connection to this story at all.

But back to the story. Scary to think that you can't detect it until it has already poisoned you and your body is shutting down.
