Maybe I’m squeamish, but I would not want to eat the meat of an animal killed by a poisoned arrow.
To this day, most human evolution occurs during tribal warfare. Poisoned arrows were certainly used on tribes of illegal immigrants trying to poach food benefits from other people's hunting grounds.
Its not really a poison so much as a drug.
From Wikipedia:
Buphedrone, also known as α-methylamino-butyrophenone (MABP), is a stimulant of the phenethylamine and cathinone chemical classes that was first synthesized in 1928. It is a synthetic analogue of cathinone, a stimulant naturally occurring in the khat plant. Like many other synthetic cathinones (e.g. mephedrone), it is also found in so called “legal highs” (sometimes also called “bath salts”), a class of designer drugs used to bypass legal restrictions.
Africans still chew on khat stems to get high.
Many toxins that affect the nervous system if injected into the circulatory system are harmless if ingested into the digestive system, and most are readily digested. OTOH, most digestible substances injected into one’s blood are no good. Inject a pint of milk into your blood and you likely won’t survive it.
Unless the meat was cooked well done.
