What does HCN or H2S poisoning feels like?
I'm not reallty sure wheter this is the right place to post this, but here it goes:
I had carbon monoxide poisoning when BBQing in a closed space. Shame on me. I felt awful, extremely dizzy, confused, weak and I had to be taken to a
hospital. At least the food was good. Anyway, after that, I started wondering if HCN or H2S poisoning would feel the same way. Sooo....What does HCN
or H2S poisoning feels like?

I'd imagine that people with first-hand experience of cyanide poisoning are pretty uncommunicative . . .

IIRC, there is a detailed account of hydrogen sulfide posioning on the forum, including a self administered nitrite antidote. UTFSE.
U.T.F.S.E. and learn the joys of autodidacticism!

It should feel exactly the same in all three cases with the only variable being ppm toxicity & exposure concentration variation. They all form a
complex with the iron in mitochondrial cytochrome enzymes inhibiting cellular respiration.
But I have no first hand experience to confirm they feel the same.

I have been exposed to prussic acid, shit stinks to me. But its very noticeable feeling, dizziness slight confusion , slight intoxication
disorientation . That was after a distillation and was only about 20 ml of hcn, exposure was very brief as I would hold my breath during transfer of
the
acid to sodium hydroxide. Ive done this many, many times , one time I thought I was gonna
throw up and pass out so I went outside. I would say if someone were to think about doing this be really careful cause it can kill.

a couple times when i made CaCl2 from roasted egg shells and HCl, there was some H2S gas evolved along with the CO2 during the reaction. while
possibly not enough to be toxic, it was very smelly; but my sensitivity to the smell became reduced; and i noticed a qualitative difference on my skin
and hair, after exposure: a gritty feeling (elemental sulphur?).

I would assume it wouldn't "feel like" anything. Don't you go numb? I've experienced a strong and accidental wiff of nitrogen dioxide. It's
incredibly burny in the olfactory area. Like what I assume spraying a can of pepper spray into your nose would feel like.

H2S is toxic. Excessive exposure will paralyze the breathing muscles which of course can be fatal.
Hi, I am fond of doing researches on herbal extracts and related drugs. I am happy to discuss with you from scientific groups and would like to share
my topics and views on medical herbs.

Doesn't it actually inhibit the same enzyme required for cellular respiration as HCl?
By the way when I made benzamide 2 years ago I experienced very uncomfortable dizzy feeling like I was gonna pass out and I noticed a weak fruity
smell, maybe benzonitrile? I think I did heat benzamide too much and decomposed it somehow.

KCN i know a person who was attempted to be removed with, it was dumped in the persons coffee..
the person had symptoms as of having been under a tanning light for too long..
person went to hospital and they just kept the person there for 2 days because they found something quite interesting in that person's body..
cyanide..
http://www.cmaj.ca/content/180/2/251/F1.expansion.html
im not sure if this would also be symptoms with HCN? could be?
now were at poisoning.. a classmate once decided to take a deep whiff of a 25% NH4OH bottle, he hit the floor before he knew what happened.. lols
also, most of us know how nitric acid smells, but dont EVER breath it in through your mouth, keep mouth shut at all times.. it burns very hard in your
throat

Yesterday I accedentaly found out that nitric acid fumes can really unclog a stuffed nose.... unpleasently.
Once I had a jet of ammonia gas sprayed in my face I inhaled a lot it stung but I didn't come even slightly close to passing out, so why would it
happen to your classmate?

bismuthate there was a hooked on phonics commercial on t.v. a while back about a lady who didnt know how to read.the dumb but pretty lady opened a
bottle of household ammonia at the super market and took a good whipf and guess what happened?she woke up on the floor with liquid spilled all over
the floor.the manager asked why she sniffed on the bottle and she did not want to say because she could not read.i need the grammar version of hooked
on phonics but it wont keep me away from ammonia.i love ammonia! just Nitrogen and Hydrogen,go figure!

That would have to be some pretty concentrated ammonia. I have 10%, and it makes you feel as if your nose were on fire. Definitely not passing out,
though.

Phenol also works great. One time I had a cold and I took a deeper whiff of phenol from a bigger bottle. Phenol was almost pure and I have to say my
nose was clear in few hours.
Don't think it was a good idea though.

Some people inhale steam to unclog noses chemists inhale corrosive fumes.
(accidentaly)
H2SO4 will do a great job to get rid of a pesky clogged nose.
Warning may cause pain or permanent loss of smell do not talk to your doctor before using H2So4 tell your doctor if you are using any bases before
using H2SO4 for one time cold relief.

As to cyanide poisoning, it seems to act pretty fast...
There's a notorious case of an millionaire that killed himself with it, after being convicted of arson, right there on the courtroom. The whole thing
was recorded. The video can be found on the internet, if you search for Michael Marin (I won't post links here, I think it would be inadequate).
Surprisingly, from the video we can infer that cyanide gives a very painful, agonizing, death. From spy movies, etc. always seem to be so quick and
reliable. Except 007 Skyfall, where it not only kept the guy alive, but also screwed his jaw (this seems to be purely artistic-license-toxicology).
The man really wasn't smart to choose to kill himself with it. I for one would have gone for carbon monoxide. Or chloroform.

i have seen the michael marin video and his was not so quick a death unless it took him a while to swallow the poison. there was an old youtube silent
video that showed a man sprinkling cyanide onto meat and feeding it to two dogs. the dogs were tied up and although it did not show how long it took
to take affect, they seemed to be having convulsions.the dogs mouths were gaping as if choking but they were not clawing at their mouths as if an
obstruction was taking place.the video title had cyanide poison but i always thought strychnine was the convulsive agent that was banned as bane
because of the violent tremors.by the way i knew some old guys back in 1974 who are now dead but they actually added a tad of strychnine(old rat
poison) to their heroin.said to give a tracer effect.

Not so quick a death? In minutes, he was unconscious. Well, it's relative. Even nerve gas needs a few to take effect.
Also, note that he swallowed. Probably solid potassium cyanide for grain silo pest control. Took it's time to reach the gastric acid, enter the blood
stream, etc. Real suicide pills have the cyanide in liquid form, and are bitten to release it in the mouth. Also, I guess inhaling or IV'ing cyanide
would kill very, very quickly.
Cyanide seems to be one of the fastest-acting "swallowable" poisons anyway. I mean, there are faster toxic agents, but most are gases or require
unusable amounts. Arsenic and ricin, in all their infamy, take more than a day to do their job. As to the strychnine you mentioned:
"The usual fatal dose is 60–100 mg strychnine and is fatal after a period of 1–2 hours, though lethal doses vary depending on the individual." -
From Wikipedia
I mean, just think about it. You can't get faster than cyanide, with it's great solubility in the stomach juice, and cellular-metabolism-blocking
toxicology.
Or can you? Lovely subject, really.
