I can relate to that I was dating this guy and I couldnt figure out how I was getting so drunk off 3 or 4 drinks (I'm a heavy Irish drinker). Come to find out he was giving me GHB in my cocktails. People need help, that's a good idea because in hindsight it made perfect since but at the time it was the last thing I was thinking. You live with someone and learn to trust them, I wish I had known red flags about the drug and more information sooner. Like if you end up in the ER it can be gone by the next morning, meanwhile the ER just thinks your heavily drunk. Thought it was lack of sleep, not eating enough, maybe me taking my medicine at night with the cocktails nope someone being an *sshole

Fun Fact:- Cynaide does not smell like bitter almonds Bitter almonds smell like dampened cynaide Because Bitter almonds contain cynaide

[@BlazeRhodon]

More precise amygdalin, which can be transformed by chemical reactions to hydrogen cyanide. Bitter almonds themself does not contain hydrogen cyanide and they are although not good, they aren't also poisonous (they are source to make a hydrogen cyanide, but not the only one). Once by accident I ate few of them but I did not get poisoned.

[@christopherleubner6633]

Cyanide smells a bit sweet, like amaretto liquor. First smelled it when I caught a big yellow and black centipede as a kid. They make cyanide as a defense mechanism apparently.

In pets at least, the treatment for ethylene glycol poisoning is IV ethanol. Yes, if your dog drinks antifreeze, the vet saves it by getting it drunk!

Yup. Same applies to humans when they are experiencing methanol poisoning.

[@royedmundson3833]

Dogs are twice as susceptible to ethylene glycol as humans, also to cyanide. Chocolate will kill dogs too.

[@ThaFuzzwood]

It works by keeping the enzymes that would oxidize the ethylene glycol to glycolic acid busy by converting the much more abundant ethanol to acetic acid. Or in case of methanol, the DNA-destroying formaldehyde.

She mentioned the beautiful flowers on all the bushes around, and she was planning to pick some leaves to see if they made a good tea. "No! Absolutely don't do that! Oleanders are very toxic." At first she thought I was joking, but someone else confirmed it to her. I spoke to the administrators who decided they should remind all residents of this fact in the next weekly newsletter.

A small hospital might have to wait weeks to get a result back, even though the test itself takes a few days.

They still do have to outsource some tests, because the internal lab won't be able to do every single test imaginable.

I had an old white lady neighbor whose dog mysteriously died. Vet found out that it was antifreeze poisoning. My mom kept a gallon of antifreeze sitting outside of our house. I had always been scared of the lady's dog because it was big and it always jumped on me. So she automatically assumed that I was the one who poisoned her dog. She got a new dog just like the old one. She secretly had cameras installed outside her house. The new dog died, from antifreeze poisoning just like the other one. She checked her cameras. Found out her own son, who live out of state came and poisoned her dog. He admitted to poisoning the first dog to. He said he did it because his family were coming for a visit and both of his daughters were scared of the dogs. He felt like the dogs got too aggressive around them.

I had neighbors that poisoned our dogs with antifreeze-soaked meat, growing up. I sell remember the poor puppers throwing up, drooling... I remember them mentioning the crystals forming in them at the vet. It was so horrible... we couldn't do anything to confirm he did it, even though we knew and he even bragged about it later, so no justice was served, either.

Thank you for this video it’s very informative. I came across it because I had a random moment of curiosity about ‘invisible’ poisons. Years ago I heard the term (and sorry for the misspelling)… but what about Sacomaglichol… it kills cells but then turns everything else into water. So essentially it just breaks the human body down to it’s essential components (Oxygen and Hydrogen). There for starving all of the systems. Sorry for my ignorance but this is something I heard about from ‘Bones’ which is by now a very dated TV series 😂

Very interesting tidbit of information concerning ethylene glycol poisoning: National Geographic and Forensic Files detailed a case where the culprit killed their victim with antifreeze-laced Gatorade. After reading about this case, a friend showed me the episode and I told him that I knew how it ended the moment I recognized the pattern of how the poisoner was poisoning the victim. I said, "I know exactly how this ends and exactly what the murderer used to kill his victim. I won't spoil it, but you'll find it interesting." Moral of the story? Murder by poison is often caused by people closest to the victim and poisoners are often very good liars, often pathologically so.

[@cynthiakeller5954]

My great grandfather poisoned and killed at least 5 of his wives, he had 9. They were immigrants and all in their 20s, he was old. I don't think he killed any of his kids. He would abandon them with his dead wife's families. He was an herbalist in S Texas. My grandmother, other side of the family, sent me the recipe for oleander tea. I threw it out as soon as I saw it.

[@a.kitcat.b]

This is extremely fascinating, I always was interested in poisons!! Maybe not as a career, but maybe as just brain knowledge just in case I need to kill something.

[@psquared96]

I would have thought Ricin and Nutmeg would be on this list because Ricin is found in Castor Beans so it would be hard to determine whether a poisoning was caused by self inflicted accident or murder. And with nutmeg being a common spice used to add flavor to things, many people probably wouldn't think it would be used to kill someone.

Arsenic also occurs naturally in the soil in many areas of the world. There are problems with it in SE Asia and Bangladesh were it can get into the food supply, especially rice from growing in the soil

[@KnakuanaRka]

Also, fun fact about ethylene glycol: the best antidote for it is alcohol. At least according to Chubbyemu, it’s processed by the same enzymes as those that process ethylene glycol, and is preferred by them; as long as there’s alcohol in the body, the enzymes will mostly digest that, meaning the glycol is digested slowly enough that the body can handle the byproducts as they come.
