They tell you this for various reasons such as if you get rid of the poison in the stomach, they won't be able to test for what it is, some drugs cause you to relax, so you can actually suffocate in the process of puking because your body doesn't have the strenght and in the modern times, if you live in the first world countries, the ambulance can come faster and so it safer. This is not the truth for about half of the world we live in. Not everyone has this privilege. Some people live in poor countries and some live very very far from cities with hospitals in them. And ambulance will definitely not come for someone living in historical fantasy world.... There are also cases even in modern world where this first aid works such as in cases of taking too many vitamins or painkillers. If the help is immediate and you know what you are doing, there won't be enough time for the drugs to be absorbed in the first place. I was saved like this btw. The ambulance would come too late and I would die.
To simplify, you are correct in the optimal circumstances in the modern world because the ambulance can arrive fast enough.
However half of the world doesn't live in optimal circumstances. Some people have to provide this first aid treatment to save lifes. My life was saved like this.
If you don't understand what people are saying, you can try using ai to translate and explain it for you. It works well.
They’re basically saying that it’s a privileged way to think. You have to live in a good country with good healthcare for you NOT to throw up the poison. In poorer countries or countries with worse healthcare, they HAVE to throw it up to survive because there is no ambulance and paramedic coming to save them.
Also vvvkkkvvv, it’s not JUST to detect the poison type or to prevent suffocation, it’s to prevent you from burning your throat and oesophagus when it comes back up. I threw up a lot as a kid, both from eating stuff that didn’t sit right with me and from eating disorder behaviours and now I have GERDs. It hurts, makes my life uncomfortable and means that certain medications are more dangerous than others. For example, things that provoke my stomach acid harm me whereas things that neutralise my stomach acid, helps. Most doctors don’t test what the poison was, they just look at the symptoms it causes and then treat based on that. That’s what they did for me when I stepped on a sea creature and got poisoned by it. Not all poison is ingested so unless they have the bottle on hand, they won’t swab your mouth for the poison. It takes too long and the labs are usually backed up. As for poorer countries, I grew up in one. That’s where my sea creature toxin story comes from. Big cities will have ambulances but small towns won’t. The healthcare can be very different depending on how big the town/city you live in is even if you’re living in richer country. I’m living in England right now and some places are actually quite inaccessible for ambulances to easily get to. Just to put into context that yes, certain countries are more privileged than others but within the country, some towns are more privileged than others too.
I never knew I had it because no one told me but I have another throat condition so I just do what I’ve always done for that condition and it apparently helps with the gerds too! It’s quite a fortunate turn of an unfortunate event. I guess two negatives really do make a positive lmaoo thanks for your concern tho!

Tbh punching someone in the stomach is such a retarded way of making someone puke out poison. The writer has no idea how to do first aid...
For those that don't know, you want to make the person that ingested pills or whatever else gag by pushing fingers into their throat or some other object, preferably clean one. (This doesn't work for having chunks stuck in throat or lungs obviously)
