Yes, cyanide kills you in more ways than Wonder bread makes you stronger (More than 12). It was this reason it was once thought to be a humane form of execution. Too bad, you would also need to find some way to keep it out of the general environment wherever you deployed it for executions. The neighbors might suffer health issues.
Then there was Love Canal. Anyone here remember that one? Because an industrial firm dumped something like 20,000 tons of trichloroethane at a local landfill where it leached into the water table, a whole community started getting Hodgkin's lymphomas and acute lymphocytic leukemias.
This incident is near and dear to me because although I didn't live there, the same chemical was used at our factory to machine parts and clean printed circuit boards. I suspected it was highly toxic as it had dissolved all but the stone from the leaky faucet stuck in the side of a 55 gallon drum of it stored behind the facility. We carried small quantities of it inside to work with, but did not store it in approved containers. Neither did we have adequate ventilation in some of those areas, nor even material safety data sheets to warn us about how dangerous a chemical this was. Needless to say, as the years went on, there was a lot of attrition at our plant from breathing the vapors, getting it spilled on bare skin, & etc. I think I got a speck of it in an open can of soda, and guess what? That's right, I got a malignant Hodgkin's lymph node on the side of my neck about 6 months later. It cost me a spleen (removed for radiotherapy), a thyroid gland (destroyed by the radiation), and oh, by the way, anything resembling a normal life until I somehow with some difficulty survived to the ripe old age I enjoy today.
The moral is: Don't be stupid: take all prudent precautions when dealing with solvents or dangerous chemicals. It could cost you your life, literally.
