Yes, they would, and after giving more thought to the matter I decided something would be "poison" only if it is harmful in any dose, no matter how small. That would make weed killer poison, but not alcohol or barbiturates (both of which kill if you ingest enough). The trouble with that definition is that I believe you CAN give people weed killer in small enough doses that it doesn't kill them. So, I give up because it's making my head hurt.
And three guys (think they were Thai?) who gassed themselves in their cars. The first guy (check shirt) has the over-healthy pinkness of carbon monoxide and think he may have messed his jeans, the other two have thoroughly pissed and soiled themselves.
Hardly need to point out that this guy emptied himself massively into his green boxers as he was dying
This guy seems to have totally crapped the front of his shorts, so I'm guessing he was convulsing face down when his bowels emptied
And this guy also shat in the back of his briefs
And take a closer look at this guy - he's died with a hard-on and every detail is visible through his black CKs (so I'm guessing they're soaked with piss though you can't really see it)
And three French-African guys - apparently the go-to poison for suicide there is a rat poison called Sniper, so these guys Snipered themselves. It's not a pleasant way to go apparently, and the second guy clearly emptied liquid shit into his shorts during his final convulsions.
