That is not the only effect of scopolamine. It's a very potent deliriant. In Colombia it has been used by attackers (referred to as "devil's breath", blown into the face) to cause amnesia and a very docile state (a victim might be walked to an ATM, forced to empty their accounts, and not remember a thing. Or worse). It can cause some extreme types of hallucinations.

From your comment:

> referred to as "devil's breath", blown into the face

I've read similar reports in email chains in the 2000. Like the guy that touched a piece of paper and a few seconds later collapsed. I think that some local newspaper even published it, without evidence.

From the NYT article:

> She carried it from a restaurant counter to their table. He had two spoonfuls, Mr. Valdez, 31, said. “And that’s the last thing I remember.”

> He drank a pink soda, he said in a video, and later awoke to find his wallet and phone gone.

> One 42-year-old man from New York recalled being drugged by a Tinder date who served him a rum and coke that he said knocked him out for 24 hours.

These case makes more sense. There are a few recent similar cases here, and many buildings have security cameras on the front door, so they get a nice video of the escaping thieves.

temp0826•4w ago
Yah I think there's a lot of urban legend around the stuff. I know a few people who have used it (well, Brugmansia plants that contain it anyways) as part of their apprenticeships (Amazonian plant medicine, in conjunction with ayahuasca) in a more controlled manner and even then they have some wild stories about it (waking up naked in the jungle, covered in scratches with no memory etc). It lasts a looong time.

WillAdams•4w ago
How was it determined that these are arrowheads, as opposed to atlatl darts?

The oldest known/discovered/documented bows only go back to ~7,000 BC (Holmegaard bows from Northern Europe).

chrneu•4w ago
Can't directly answer your questions, but generally each region/time period has their own style of arrowheads, so my assumption here would be that this region tends to create arrowheads in this style. The paper mentions this is a pretty old site/artifacts, so I'd wager they found other "arrowheads".

Arrowhead might also be being used generically here to mean sharpened stone tip on a projectile or thrown weapon.

I'm no expert in this area, but it may just be that we aren't sure if these are arrowheads or just sharpened stones that were put on something. Someone correct me if I'm being ignorant. The article really makes it seem like a lot is unknown here, since we're dealing with 60,000 years.

Twiin•4w ago
There are a number of ways they're able to tell the difference between arrowheads and sharpened stones put on a stick, including high-resolution CT to look at the stress microcracks of the arrowhead. Bow-fired arrows and thrown spearheads have different launch stress profiles as well as impact profiles. There are a lot of overlapping types of analysis that happen to establish what technology did or did not exist in a given area at a given time.
narag•4w ago
You can throw the arrow with just a piece of rope rolled around your hand and using the same grip as in the atlatl. Romans called those slingshot arrows tragulae.
icyfox•4w ago
At the risk of being overly pedantic, topologists would typically classify this as venom.

Venom is inert if digested; it's only a problem if it gets in your blood stream. So arrows that were laced with venom and thereby contaminated meat were actually perfectly safe to eat.

Poison is different. If ingested, inhaled, or absorbed it will kill you.

VanshPatel99•4w ago
TIL. I always thought that "If it bite you -> you die = venom" and "If you eat, bite, touch -> you die = poison". But your differentiation makes more sense
zahlman•4w ago
That explains the words "venomous" and "poisonous" used of creatures.

It's different for the actual substances. Although it relates: a venomous creature that bites you will release its venom into your bloodstream.

anonym29•4w ago
>a venomous creature that bites you will release its venom into your bloodstream

unless it's a bee, wasp, hornet, scorpion, stingray, jellyfish, man-of-war, platypus, lionfish, stonefish, sea urchin, or catfish, which all have venom instead of poison, but the delivery mechanism of said venom isn't biting

zahlman•3w ago
I said "bite" echoing the comment I was replying to. Obviously the same applies, mutatis mutandis, to stinging etc.
hearsathought•3w ago
If a venomous snake bites you, you die. If you bite a venomous snake, you live. If a poisonous snake bites you, you will. If you bite a poisonous snake, you die.

Or Hamlet's mother died by drinking poisoned wine. Hamlet died by being stabbed with an envenomed sword.

hyrix•4w ago
These chemicals are derived from plants where even pedants would classify them as poisons.

The genus name Boophone is from the Greek bous = ox, and phontes= killer of, a clear warning that eating the plant can be fatal to livestock.

icyfox•4w ago
Fair point about the source, but the classification usually follows the mode of delivery, not the organism of origin.

Many plant-derived compounds function as venoms once introduced into the bloodstream (arrow coatings, darts, etc.), even if they’re also toxic when ingested. Curare is one example of a plant-based compound - lethal in blood, but largely harmless if eaten.

So while Boophone is absolutely a poison in the ecological sense, using it on arrows still fits the venom/toxin distinction better than a purely ingested poison. Otherwise why would people hunt with this if they got sick the second they ate the meat?

jeltz•4w ago
Is it really? We call it poison darts when hunters use poison from the poison dart frog to hunt.
cluckindan•4w ago
Huh, so telephone is killer of distance and Persephone is killer of… Persians? Grain? Vegetation?
stared•4w ago
You're mixing up phōnē (voice) and phonos (slaughter), but the truth about Persephone is actually more metal.

Her name predates Greek contacts with Persians, so the timeline doesn't fit. Instead, it comes from perthein (to destroy) + phonos, making her the "Bringer of Destruction". With a caveat that the etymology of her name is uncertain: https://en.wikipedia.org/wiki/Persephone#Name

I do like "killer of distance" for telephone, though. :)

thaumasiotes•4w ago
> Instead, it comes from perthein (to destroy) + phonos, making her the "Bringer of Destruction". With a caveat that the etymology of her name is uncertain:

But... of all the theories listed there, perthein isn't among them.

And if the roots are "destroy" and "death", what would make her the "bringer" of destruction?

skrebbel•4w ago
We Dutch solve this problem by having a single word for "poison", "venom and "toxin"¹. Everybody still knows what you mean and nobody gets to be pedantic.

¹ and "badly compressed looping animation"

gambiting•4w ago
Same in Polish. You'd just call both of these "trucizna".
mbel•4w ago
Not really, we have both „jad” (venom) and „trucizna” (poison).
gtech1•4w ago
How does this happen ? The poster above you isn't really Polish ? How can someone that claims to know Polish not know there's two different words ?
gambiting•4w ago
Obviously I know "jad" but I don't see any issue with calling venom "trucizna". Natural languages aren't C++ and you don't get compiler errors when you speak - to me, there is no issue calling both venoms and poison trucizna. Polish dictionary doesn't seem to contradict it either:

https://sjp.pwn.pl/slowniki/trucizna.html

The point is, both are correct(afaik) while in English venom and poison are definitely two different things.

mbel•4w ago
Nobody would say „trujący wąż” (poisonous snake) or „jadowity grzyb” (venomous mushroom). The distinction is similar to English. There are exceptions and contexts where it can be used interchangeably but arguably the same is true for English.
gambiting•4w ago
>>Nobody would say „trujący wąż”

No? That's how I've always said it. "Ta żmija jest trująca" - don't see any issue here. Jadowity grzyb I'll agree.

gtech1•4w ago
This is fascinating, assuming you are both natives of Poland. Is there as much language variance in Poland as in, say, Italy ?
gambiting•3w ago
No idea how much variance there is in Italy so not sure how to answer that question.
gtech1•3w ago
Italy, the core remnant of the Roman Empire, has unmatched language diversity, often varies even from town to town. It's a colorful mosaic of micro cultures and customs where people from one region using different words for venom/poison is completely normal, in their local dialect. Everyone speaks standard Italian though.

You've never visited Italy ? They're not that far away and I'm sure you'll love it.

thaumasiotes•4w ago
> The point is, both are correct(afaik) while in English venom and poison are definitely two different things.

No, the situation in English matches your description exactly: all of these things are called poison. The word venom is almost never used in natural speech.

Furthermore, if you ask English speakers what the difference between poison and venom is, by far the two most common responses will be "there isn't one" and "I don't know". icyfox is just looking to be annoying.

(Another popular option will probably be "it's called venom when you're talking about snakes", which explains roughly 100% of use of venom in natural speech.)

usrnm•4w ago
And in Russian we use "jad" ("яд" in cyrillic) for both. Although there is the word "отрава", which can be used for poisons and "яд" is closer to "venom" the difference is almost non-existant and both are often used interchangeably.
XCSme•4w ago
Is the word "stamppot" ?
usrnm•4w ago
Just "food". Any kind of Dutch food fits the description.

tharkun__•4w ago
Remove Ver, add t and you got German: Gift

Vergiftet would be past tense.

Funny that in English gift is a word but entirely different meaning.

Languages are fun, especially in Europe where they're all different but all so related but everyone does not want to admit it.

animal531•4w ago
It's probably the same, for example in Afrikaans its just gif. Vergif is the verb action of doing it, and vergiftig the same past tense of it having happened previously.

And Basque, Maltese, Turkish and Georgian.

Magyar (Hungarian) and Finnish are both Uralic languages along with Estonian and the Sámi languages, but none of these are related to the Indo-European languages common in the other parts of Europe.

And while most of Europe’s extant languages are in the Indo-European language family, there’s still a fair number of differences between Albanian, Germanic, Hellenic, Celtic, Romantic and Slavic languages.

tharkun__•3w ago
Oh for sure there are many differences, that comes with them being different languages, countries, ethnicity. You can do this on many levels.

The point was essentially what you're showing here: People focusing on all the differences instead of shared history, languages influencing each other and how we're all not that different in the end.

If you want to, even within what are nowadays countries and what outsiders would say is "one language" and "one ethnicity", you can start focusing on differences and make people dislike each other.

SllX•3w ago
That’s fair. I tunneled in through a linguistic lens.
thaumasiotes•4w ago
> Funny that in English gift is a word but entirely different meaning.

In English it maintains its original Germanic meaning derived from the verb give.

The sense of "poison" in German comes from a euphemistic use of "gift". (Literally 'something given' but actually used to calque Greek "dosis", which also literally meant 'something given', but was used to mean 'dose [of medicine]'.)

https://en.wiktionary.org/wiki/Gift#Etymology

Summing up, the reason gift is a word in English with an entirely different meaning from what it has in German is that everyone in Germany forgot what gift meant.

(The reason it's gift and not something more like yift is the Danelaw.)

tharkun__•4w ago
This is one of the reasons I like HN: Random knowledge transfer like this. Appreciated!

Also: in German Dosis is the word for dose.

    Die Dosis macht das Gift
(the dose makes the poison)
bruce343434•4w ago
In NL, just 'gif' is sufficient
pjmlp•4w ago
Same in Portuguese, veneno.

Although there are plenty of other opportunities for pedantry, especially when we take regionalisms, and other Portuguese speaking countries into account.

Retric•4w ago
In practice the difference is mostly semantics.

Venom is still almost always poisonous when eaten and poison is harmful when injected. 2-3% as dangerous when eaten vs injected only helps so much.

readthenotes1•3w ago
"mostly semantics"

Semantics: 1 (linguistics) the study of meanings

I am not sure what could be more important.

But perhaps you "word choice"?

Retric•3w ago
What things are more important than the study of meanings in a linguistic context?

Well semantics only covers an infinitesimal fraction of all meaning. Consider if I inject arsenic into a snakes venom sac is it now a venom? Nothing about your answer changes anything about what’s going on, yet you could still debate the question.

So when you say “what could be more important” I can only say that just about everything is more important.

I am not a native speaker but I believe you are wrong. It is called poison dart for example. So injected toxins can be both called poisons and venoms.
mrleinad•4w ago
In Spanish it's commonly "dardo venenoso" (venomous dart), no "dardo ponzoñoso" (poisonous dart). So it's probably incorrectly used in English.

shevy-java•4w ago
Man has a rather unkind history.

The even worse thing is that in 2026 this hasn't quite improved significantly. What is the main poison used today? I guess that may depend on the definition, probably particles being taken in by the lung in general. But specific poison it may be antifreeze? Or perhaps that is just more famous. Food poisoning probably is among the highest, but it would not be deliberate usually, so it should be counted in another category.

jayzalowitz•4w ago

It was almost certainly used for agriculture. Observation of hunter-gatherer bands in modern times, and archeology have little in the way of skirmishes or warfare prior to the agricultural revolution 10,000 years ago.
