1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners.
The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

Nitrogen asphyxiation should be effective and painless, but not if the person fights it. Which means it'll be hard to use as an execution method (unless you surprise them with it somehow)
You could give them a sedative. They pass out and can't hold their breath, then you administer nitrogen. You could probably even find an acceptable oral medication so you wouldn't require a doctor to administer it. I'm in no way saying this is acceptable, but it isn't that difficult.
Hell, regular suffocation isn't that bad if you stay calm and relaxed and accept it. It's all about the state of mind, and someone being murdered isn't exactly going to be meditative about it.
My understanding is that we can't detect oxygen deprivation, but we can detect CO² buildup which is the idea behind nitrogen asphyxiation. Wouldn't regular suffocation (like, something obstructing your airflow) be quite agonizing then in comparison due to CO² buildup?
Complete tangent, but I don't think superscript numbers are a good choice in chemical notation. You're trying to use them here to stand-in for subscript numbers, but superscript numbers have a meaning in chemistry as well. They denote ions.
So, I think CO2 is more accurate than CO², since it could be confused as carbon monoxide with some sort of ion of charge 2 (unclear of positive or negative).
I think Jerboa can do subscript
CO~2~
Yup, looks right for me. It's a single tilde on both sides of the 2.
There’s a unicode character for it, meaning every decently modern form of text input should support it: CO₂
That's a good point. My phone keyboard has the superscript so I used that without thinking too much
It's certainly not pleasant, but not outright painful. The bad part of it is you feel like you should be panicking and struggling and fighting to breathe. If you're rebreathing your air, so you're not prevented from inhaling, and you take long, slow, breaths and keep calm and relaxed, it's not nearly as unpleasant. I had a near suicide attempt where I gave it a try to see how bad it would actually be and it was scarily not as bad as I thought it would be. Granted I didn't take it to unconsciousness or I wouldn't be here to talk about it, but I got to the point my vision was getting fuzzy so I think it's far enough to draw this conclusion.
I want to warn anyone thinking of trying this: don't.
Obviously there's the don't commit suicide part, and that's the most important part. But also, as someone who has unfortunately spent time considering various methods, I can tell you: don't even consider doing it this way.
Genuinely sorry to be contradictive, but you absolutely would have been in a painful situation if you'd continued. The only explanation is that you didn't get to the point that your body 100% takes over from you and forces a desperate, painful, writhing attempt to get air.
You would die of increased CO2 concentration in your blood long before you actually ran out of oxygen. That increased CO2 would be very painful. Like, lizard brain stem absolutely taking over, full panicking levels of painful. Don't try it!
You DON'T GET the CO2 concentration in proper nitrogen suffocation. Most people that are in oxygen-free environments don't even realize that it's happened; they get lightheaded, short of breathe, then black out and die. Any gas that's heavier than air and isn't CO2 can cause that kind of suffocation in an enclosed space, which is why SCBA equipment gets used in a lot of industrial applications. For instance, welding in enclosed spaces? The argon or nitrogen can easily kill you before you realize you're in any danger.
If you, for instance, connected your CPAP mask to 50# nitrogen tank, and cracked it open, you'd be breathing in straight nitrogen, and exhaling CO2. There would be zero CO2 buildup. As a result, zero panic. The problem is when you try to displace oxygen, but not CO2; you need to be displacing both so that you're not rebreathing your own CO2.
Yes, this is true. Using an inert gas doesn't cause CO2 toxicity, but rebreathing atmospheric air does.
Surprise execution?! That sounds like fun
Thought experiment:
Put them in a small sealed room with airflow you control. Using a randomly generated number to pick the start time (within some maximum that's deemed appropriate), you then throttle up the nitrogen and throttle down the oxygen.
The time spent in the room would still be pretty terrifying so I doubt it'd be much better than the mask... Maybe the room is their cell and it's a randomly chosen day within an execution "week" where you make sure they're asleep first?
Probably best just to not kill people of course, but if you're gonna do it, do it the most humane way possible.
That would be colossal.
Only if they make it a live sporting event and I can buy a churro while watching. I guess I just want the Roman Colosseum back.
At this rate of dystopic advancement, it'll be sooner rather than later
Tbh I would love nothing more than for my friends to throw me a surprise euthanasia party. Reminiscing, having a good time, then they suffocate me or something.
