More interesting info on chloral hydrate ...
It is a byproduct of water chlorination and is quite caustic.
If you INJECT it you run the very high probability of an ABSCESS forming. It is NOT injected when administered properly..it is either oral or in a suppository.
One wonders if ANS's upset tummy was protesting drugs orally (vomiting as reported) and someone (????) got the bright idea to draw chloral hydrate up into one of the syringes and giving her a shot instead of shoving capsules up the backside.
As noted, chloral hydrate does not get along with human skin or tissue and it probably burned like fire and immediately started going the wrong way with the result being an abscess.
If so, ANS would be reluctant to go to the hospital and fess up she was shooting up sleep meds improperly or let it get out she had a big pussy abscess on her bum.
