arsenic, also known as inheritance powder

Spent a lot of the day coding various sorts of "accidental poisoning" disorders. This would be cases where someone has accidentally taken a poisonous substance, I hastily note, rather than any sort of deliberate poisoning, or self-inflicted poisoning, which have quite different external cause codes.

I couldn't help recognising some of the substances from previous crime fiction reading. But I decided not to go on about this to my coworkers at too much length. It might have ... worried them.
