Method Nitrous oxide as a method?

[Intoxicated]

Wrong thread??? I was just playing COD mobile though. But yeah what's the thread you meant to reply to? lol

I think, in that context, its intended meaning is "cause of death", not "Call of Duty" )

Oooohhhhh. Lmao. Second brain fart.

 

[OzymandiAsh]

Any thoughts on combining nitrous oxide with an opioid OD (codeine in my case) and maybe some alcohol? I will likely do the OD either alongside or just before going with nitrous, if only because I want to know how it feels. I will be taking some meto beforehand.

Answered my second question by testing the cylinder by directly taking the nitrous into my mouth from the slightly opened valve and nozzle.

No noted negative effects. I can immediately see why people like it. I guess socially it could be conducive to a good laugh in some ways, but personally I just feel a bit of dissociation, detachment from my body and relief, mainly.
It does make me feel a bit faint even at lower amounts, so I can see this working and can see myself going unconscious at higher amounts.
Feels light, and like release.

No serious negative effects on my skin, lips and mouth, but I turned the discharge nozzle only slightly to release a small amount of gas at a small pressure, then turned it back and closed it when I was done. I do not recommend doing this if you are an idiot who cannot keep the pressure down, because more pressure can easily fuck up your skin, teeth, lungs and so on. But at a small amount of pressure, it's not extremely cold, and has a slightly metallic or icy taste reminiscent of whipped cream cans and dental appointments where they spray that high pressured air (or nitrous idk which) all around your mouth.

Hell yeah. Might have to buy another cylinder just so I can waste one getting high and pushing the boundary before I CTB (hopefully within a couple months time).

I'm really surprised you didn't find it unbearably cold when u tried gas directly in the mouth.I thought this would have caused frostbite,at least localised.
I'm looking at filling the bag while wearing it(to minimize air contamination as opposed to fill and wear)and this is what is stopping me(extreme cold).
I'm just trying to be completely sure that it's tolerable(or not) before choosing this.

That was said in a different context. When the bag is properly sealed, you can eventually use up the residual oxygen to the point when its concentration will no longer be sufficient for maintaining life. In particular, breathing a gas mixture containing less than 6% O₂ at normal atmospheric pressure is fatal in a few minutes - see

Oxygen Deficiency Hazards and Asphyxiation

ehs.lbl.gov

25 - 30% air corresponds to ~5.2 - 6.3% O₂ (assuming that air contains 20.9% O₂) with ~19.8 - 23.7% N₂ & other gases.

The wonderful story about the survivor implies that the concentration of oxygen was sufficient for maintaining life in that case. In order to keep someone alive and sedated with N₂O, a constant supply of O₂ and N₂O is required (after administration of N₂O is stopped, its sedative effect wears off in a matter of minutes). A possibility of passing out for days from a reasonable amount of nitrous that could be used for a real CTB attempt seems rather unlikely.

For closed system,wouldn't adding an elastic cord to the bag(like exit b) be a good idea to reduce air contamination?-
When bringing the bag down to neck,the elastic ensures it hugs your head while coming down.
I'm guessing the gas filled bag would still need to be clenched shut/sealed after filling(before wearing) as the elastic won't seal the bag opening without head but once it stretches around the head it should.
I would still insert bag sideways.and zip tie.
This gives u an extra hand zip tie as u don't need to hold the bag sealed while u zip tie.

Do u think this is unnecessary or good value added step?

My teeth are sensitive so if it was cold I would know about it. Nah it wasn't that cold, so as Intoxicated suggested earlier in his signature sexy sarcastic style, you don't need to worry about frostbite unless you are in a very cold environment or whatever. Or unless (as I said earlier) you are dumb and cannot keep the pressure of the release somewhat controlled and low, because at very high pressures it can get cold. But other than that you can disregard the frostbite warning given by AI chatbots, lol, I've never heard of anyone getting frostbite from using nitrous. It didn't make the rest of my body feel cold either.

A classic rubber band will do.

That plan may require holding breath for the period of filling the bag and for the period of sealing it. If it's OK for you, then it could work.

This sounds like a good idea in any case tbh, a good breath hold just before inhaling the gas would make the first couple of inhales massive, then its lights out.

Not necessarily talking about hyperventilation, just a breath hold. Although I'm unsure what would work better, holding breath until bag is sealed around head, then exhaling and inhaling in bag, or, holding breath, exhaling as much 'air'/CO2 as possible just before sealing bag over head, then deep inhaling after bag is sealed. Probably the second I guess.

Ai is extremely unreliable for things like this I've found.I don't utilize it for these things usually.
Filling with gas while wearing is what I think would have the least air contamination. Questions on cold were stopping me entertaining this way,If it's tolerable then that's great.

AI was the only thing that warned me about frostbite so I assumed others here who were concerned about it might have gotten their concern from the same place. Nevermind.

Yes, in fact if you can fill the bag with nitrous while it is still flat, that's even less air. Like when you buy a roll of black bin bags, and take one while it is still flat, seal the opening around the forehead, and fill it up at the seal, before bringing it down to cover the rest of the head. Like an inflated balloon hat. Then I will exhale the air from my lungs, bring the seal (rubber band and bag opening) down to my neck, and take a huge inhale. That's an idea I've borrowed from someone here, should mean even less air getting in.

Putting the bag over the head by lowering it is probably not the best approach, since N₂O (especially when it's cold after evaporation of its liquid form) is denser than air and tends to flow downward at a direct contact with air (while the air will rise, displacing nitrous oxide above it). If the head is tilted so that the bag can be lifted towards the neck or at least moved horizontally, this should reduce the amount of air entered inside. As long as the percent of air doesn't exceed 25 - 30%, it shouldn't cause complications.

It was found that anaesthesia can be obtained with mixtures of nitrous oxide and air, provided the latter does not exceed 30 per cent. With 33⅓ per cent Hewitt failed to induce complete unconsciousness. With small percentages of air the symptoms were practically identical with those produced by the pure gas. The greater the proportion of air, the longer was the inhalation period before symptoms of anaesthesia appeared. Thus with 3 per cent and 5 per cent of air the average inhalation period was 69 secs.; with 30 per cent of air it was 148 secs.

It is an interesting fact that there was more anoxaemic convulsion with 3 and 5 per cent of air than with pure nitrous oxide, the explanation being that, in the absence of all oxygen, obstructive stertor comes about so quickly as to cut short the intake of the anaesthetic gas before the blood has become sufficiently altered to induce any marked convulsive seizure. With higher percentages of air the anoxaemic muscular phenomena progressively lessened, disappearing altogether with 30 per cent of air. With moderate percentages of air the clonic movements were but feebly marked.

The time to LOC is less than the time needed to produce anesthesia (basically a comatose state) mentioned above. In case of inhaling pure nitrous oxide through a mask,

The time which elapses between the commencement of the inhalation and loss of full consciousness is extremely short, about twenty to thirty seconds on the average.

This man succeeded with a relatively small bag (filled with helium)

Asphyxial Suicide by Inhalation of Helium Inside a Plastic Bag | 10.1097/paf.0b013e31815b4c69_Science Hub

tesble.com

By using a large bag (with a large amount of the gas) you extend the limit on the absolute amount of air that can enter inside and form a permissible proportion to N₂O, without critical impact on the effectiveness of asphyxiation.


As I said above, nitrous oxide is denser than air, and this feature should be taken into account when choosing the orientation of the bag and its relative position to the head.

That being said, I am still trying to wrap my head around this (so to speak), so I might incorporate some kind of tilting or whatever. I'm having trouble picturing it though. Ideally I'd like to asphyxiate while lying down in bed, so that's something I'll have to figure out. Possibly I could seal the bag horizontally around my face (rubber band stretching between just under the chin and somewhere near the middle of my scalp), inflate, and bring it down to cover the whole head (rubber band either just above or below the ears, and still under the chin).

I was only speaking on my experience of course and the models I tried.
What you described about bag etc,have u actually tried this?. If I did this(bag,rubber band) I fear I might fumble it up,especially during anxiety of the moment.That's another reason I was thinking of adding elastic.

 

[Jello Biafra]

Any thoughts on combining nitrous oxide with an opioid OD (codeine in my case) and maybe some alcohol? I will likely do the OD either alongside or just before going with nitrous, if only because I want to know how it feels. I will be taking some meto beforehand.

Hey bud,

Had a bit of a break but I'm still here.

What was actually occupying most of my time was I was kinda pursuing the same idea that you mention here. However, instead of opioids, I secured some benzo research chemicals which are legal. Specifically, I'm getting some bromazolam and xylazine, which is a horse tranquilizer. It is not scheduled in the US and is known as "tranq" here. Specifically, it has been in the news a lot from drug dealers using it to cut their Fentanyl and heroin, causing a massive amount of ODs.

I plan to combine both, 1 gram of bromazolam, with xylazine, and some Bacardi rum. I got the bromazolam as a powder, so I'll take some shots of rum after I take the benzo and xylazine, then lower my "kitchen trash bag", filled with N2O, over my head. I will be laying down in bed. People always act concerned that this might cause me to choke on my vomit (like Jimi Hendrix) but I won't be conscious so I don't really care.

By combining these things, I don't need to rely on getting anything perfect. I'm sure the N2O by itself would do the job, or the benzo and alcohol with a plastic bag would as well, but I'm kinda a worry wart and cannot entertain any possibility of having a failed attempt.

I originally installed Tor and was trying to do the whole dark web thing to get ghb, as I had read it was the closest thing to mimicking barbiturates - I was going to combine that with alcohol + plastic bag of N2O, but getting crypto and all that was a pain. Instead, I found easy "research chemicals" sites on clear net and went that route. Supposed to take delivery in just a few days, and according to some websites he's a trusted research chemicals dealer. I'm basically out of time as I have IRL things I neglected that are now bearing down on me.

Hey friend,

First, I know you've been concerned about the fact that the compressed N2O comes out cold - honestly, as long as you aren't inhaling directly from the cylinder or cracker, it's nothing to be concerned about. If you are worried about anxiety, you might want to try and get some benzo research chemicals if you can. If that's not possible a little bit of alcohol will calm your nerves. If that's not doable then a couple hits of N2O itself is an anxiolytic. Just take a few hits from a balloon. Don't hold them in forever so you don't pass out, but it could help calm you down.

I'm using a rubber band as I've mentioned to you before. once it's down to my neck I will probably wrap the seal with plastic wrap a few times as it's flexible and will hold nicely. Tape I don't really trust, as you have to expect there will be mild convulsions - this is a given with hypoxia, although I'm not sure if the research chemical benzos I will be taking will minimize this somewhat. They aren't tongue biting "seizures" and only last for 8-10 seconds from what I've read, but nonetheless they could be enough to cause tape to become dislodged- especially if you live in a warm environment which I do.

Yeah the dark web is really a headache, all the PGP and crypto stuff. You have to be a SuperGeek to use it lol. I'm surprised you found research chemicals on the internet, probably more difficult to get in the UK though sadly.

Even when I was inhaling directly from the cylinder, it wasn't really cold. It's only cold if you release the gas at high pressures and quickly.

Won't a rubber band by itself do the job? I managed to find some just the right size that it will fit the bag tightly around my neck, but not so tightly that I can't get the nozzle inside to inflate the bag.

I got some 23"x0.47" wide zip ties.this was the widest I could find. These also (specifically made) have no sharp edges anywhere that can cut a bag for instance.

Ya, I think the rubber band would most likely be enough. I've certainly read case reports of accidental N2O deaths that didn't even have a sealed environment. For example, I just read a news report of 3 guys in a pickup truck who simply opened a N2O cylinder with the windows up. All 3 of them died. It didn't state how big the cylinder was, but they didn't bother sealing the vents or anything like that. I could understand if maybe 1 person died, but the fact that all 3 of them did should speak to how lethal N2O can be if someone is breathing it in continously. The cab of a pickup truck is not huge, but it certainly would hold a significant volume of air. Opening a N2O cylinder in there is pretty demonstrative of the effects, especially when they weren't trying to ctb - they were just trying to get high.

As I've mentioned before, I've done my fair share of drugs in the past, and being partial to all things opiates, the actual "euphoria" from something like N2O seems non-existent to me, likewise alcohol or anything benzo related, so I don't really understand the recreational aspect of N2O, but it certainly seems to provide a pathway to the very lethal hypoxia.

My trouble with the dark net markets was more related to the horrible connection speed, and from what I was reading the fact that a lot of times those marketplaces are taken over by phishing sites that are replicating a market and tricking someone in to believing they are ordering from the legit site.

Obviously we are in different countries and have different sets of rules/websites - in the US there's been a ton of ODs lately because dealers are supplementing the lack of fent supply and cutting it with xylazine. Here at least, xylazine is not a scheduled drug, but as I mentioned it's typically used as a horse/cattle tranquilizer - so it's pretty powerful. Not sure how it's regulated in your country.

If you are considering an opioid od, as long as you don't already have a tolerance, combining that with alcohol and a plastic bag for insurance would be a pretty peaceful way to go, imo.

WHAAAAT?! With the windows up! Holy crap. RIP to the three, but honestly this makes me happy because I know this won't fail easily.

Same here, but opioids I don't have much experience with. Always been curious about heroin and the like though. So with the codeine I mostly just want to know what a strong dose of morphine feels like, even though the 1500mg I have is supposed to be in the lethal range, but apparently it probably won't kill me even with alcohol and meto according to some folks here.
I can understand the recreational aspect of N2O, but it is quite mild.

I looked up xylazine and it's been a Class C drug since last year.

There are some tricky things about combining a plastic bag with an OD, mostly the timing, you would have to time the plastic bag perfectly just before you lost consciousness and you would have to have the coordination to seal it, which is somewhat unlikely.

Ya, timing is a thing, for sure. Tbh, I don't even believe I need the N2O if I'm using benzo + tranq + alcohol + plastic bag.

Obviously the bag has to be secured before I lose consciousness, so a little grocery bag would not work as the co2 buildup would cause problems before I'm able to slip in to sufficient unconsciousness.

I plan to easily mitigate that by using a larger plastic bag. I believe Chris Docker talks about this in his "Last 5 Acts" book, or whatever it's called. By using a larger trash bag, it will be an hour or so before it fills with a level of co2 concentration that would cause hypercapnia - this is assuming I have no N2O in the bag and it's just plain air. 60-90 minutes before hypercapnia is sufficient time to slip in to a coma-like state where I won't be awakened by the co2 alarm reflex. Adding N2O to the bag is probably overkill, but N2O itself mitigates the hypercapnic response, so I like to think of it as insurance. I'm fairly confident that it's not even needed but I already have it and might as well use it.

Can I ask why you prefer the OD and bag method? It seemed like you invested a lot of time into researching the N2O and that it was by far your most preferred method, what changed?

Also, I know it sounds easy in theory but just a heads up that there might be some complications in practice. For example if you throw up, or if the bag keeps sticking to your face as you inhale/exhale. Those are not the way you want to spend your final hour or moments, so it might be worth doing some test runs at least.

You'd need a very large bag to keep the concentration of CO₂ at comfortable levels for 60 minutes.

A typical adult produces approximately 200 mL/min of CO2 at a resting (basal) rate, which is slightly less than the basal O2 consumption of 250 mL/min.

Carbon Dioxide: Storage, Transport, and CO2 Dissociation Curve - OpenAnesthesia

www.openanesthesia.org

5% is a significantly uncomfortable concentration of CO₂ - see

https://www.fsis.usda.gov/sites/default/files/media_file/2020-08/Carbon-Dioxide.pdf

https://www.epa.gov/sites/default/files/2015-06/documents/co2appendixb.pdf

After 30 minutes of breathing out CO₂ at the rate of 0.2 L/min (200 mL/min), you will have 6 liters of CO₂ expelled in total, and keeping its average concentration below 5% will need a container larger than 120 liters (0.2 L/min * 30 min * 100% / 5%). After 60 minutes, the required container volume would exceed 240 liters (if sufficiently deep unconsciousness is not produced yet).

Considering that CO₂ is not necessarily evenly distributed inside the bag (the concentration of CO₂ near the nose may be noticeably higher than that far from it) and some discomfort from excess of carbon dioxide appears at concentrations of 1.5 - 3%, for a really comfortable experience a larger bag than mentioned above for the corresponding periods may be needed. "Five Last Acts - The Exit Path" mentions 240 L, and this volume looks like a bare minimum needed to carry out CTB comfortably this way.

One can also use O2 and CO2 scrubbers.

Different breaths can produce different results. Deep exhales eliminate more oxygen from the lungs than shallow exhales would do. Deep inhales dilute the residual oxygen in the lungs more than shallow inhales would do. Also hyperventilation with air before inhaling an asphyxiant gas replaces some amount of carbon dioxide in the lungs with oxygen. Losing consciousness after hyperventilation with air followed by a single deep inhalation of an asphyxiant is likely harder than after the same single deep inhalation of the asphyxiant without prior hyperventilation.


Initially it should be nearly full. If you CTB at home, removing approximately 1/5 should give enough room for further thermal gas expansion. 25% expansion (from x0.8 to x1.0) corresponds to heating from -25 °C to +37 °C, provided that the mass of the gas is not changed, which is not the case when you breathe N₂O, because it's partially dissolved in blood plasma, so the expansion is at least partially negated by loss of the gas.

If the bag is large and inflated, that seems potentially doing a somewhat opposite to allowing maximally free breathing through the mouth. Restricted breathing is undesirable because of the hypoxic ventilatory response. The idea with mask is worth considering if experiments with the bag (filled with plain air) confirm that sticking to face really takes place.

I don't know if u read this but on one of the ctb reports u linked it said something like this man was found with several inches of the garbage bag down his throat(or bag was several inches down the throat) .
Which means he sucked it in and it was most likely a very thin and flexible bag.
Still makes me think a solution is needed?

His bag was very small and not inflated in a way that would make a good gap between the mouth and the bag. With a well inflated bag the gap should be big enough to prevent contacts with the mouth, unless you somehow flip face down.

I'll probably do the opioid OD before rather than during N2O attempt, idk. I guess I'm curious to know how it feels. Haven't made my mind up about that yet.

Yeah the dark web is really a headache, all the PGP and crypto stuff. You have to be a SuperGeek to use it lol. I'm surprised you found research chemicals on the internet, probably more difficult to get in the UK though sadly.



Even when I was inhaling directly from the cylinder, it wasn't really cold. It's only cold if you release the gas at high pressures and quickly.

Won't a rubber band by itself do the job? I managed to find some just the right size that it will fit the bag tightly around my neck, but not so tightly that I can't get the nozzle inside to inflate the bag.

Sorry

Makes sense.
I mentioned earlier I was exploring pumping gas into the bag while it's already on head..
Is it better to fill from the top or bottom?
If filling at TOP,regulator hose will feed in through small hole I'll make at top of bag.I will reinforce this with cable tie and/or tape.
After filling is complete I guess I will have to just turn off the regulator and leave the hose(still connected to cylinder) in the bag.would that be an issue?
At BOTTOM hose will go underneath zip tie holding bag to neck.after filling I can remove this and tighten zip tie.

What do u think?

IDK. Maybe whichever looks more simple for you.

Lol,I wasn't even aware I typed that.
Please disregard.
I'm on a lot of pain killers etc it's extremely difficult for me to concentrate.I do things I'm completely unaware of.
Its really a horror movie not having full control of yourself.

Before nitrous oxide, I was considering propane-butane and tetrafluoroethane (R134a), which I can obtain in relatively large cylinders, and I decided that I'd rather place a prefilled bag over the head anyway, since this seems simpler for me to do correctly.

When I checked, r134(-26C) is about 3 times less cold than n20(-88.5C)when released directly from cylinder.
N2 is the coldest of the 3 at -195C but I have not seen anyone complain about the cold even though this is the most popular one(ie.I personally haven't heard of any complaints,could always be wrong).
So,I do feel a lot better about N2O cold issue now.

You'd need a very large bag to keep the concentration of CO₂ at comfortable levels for 60 minutes.

A typical adult produces approximately 200 mL/min of CO2 at a resting (basal) rate, which is slightly less than the basal O2 consumption of 250 mL/min.

5% is a significantly uncomfortable concentration of CO₂ - see

Certainly, I have done some rough calculations based on my respiration rate, although I do not have any reliable way of measuring my individual volume of respiration, however, maybe I wasn't clear in my intentions.

I do not plan to only use bromazolam, xylazine, and alcohol along with plain air with a plastic bag. That plastic bag will be filled with nitrous oxide. My protocol will reliably insure that the amount of O2 in the bag will be at bare minimum levels, as not only will I fill a flat bag before lowering down over my head, but I will also purge the bag with additional nitrous before I actually seal the bag.

What I'm trying to say is that once hypoxia is introduced, I do not expect to carry on with normal respiration for anywhere close to what increasing concentrations of co2 would require to present a reflexive hypercapnic response. Furthermore, consciousness itself is the biggest o2 demand in the brain. Despite the fact that approximately 4 minutes of o2 is still being circulated within the blood, generally in a hypoxic or complete anoxic situation, first hearing, then eyesight, rapidly followed by consciousness itself are lost given the amount of oxygen required to maintain these systems - the diminishing o2 supply in the blood is normally used as an emergency response by the body to preserve brain cell death and the possibility to regain consciousness is basically zero at that point unless an oxygen source is restored.

So what I'm saying is that by using nitrous oxide, by the time co2 would even become a problem, I expect to be dead, or at the very least in a comatose state very near death, mostly due to the minimal o2 breathing environment which has been replaced with nitrous oxide in the first place. Even with a tiny grocery bag filled with nitrous oxide, or any other inert gas asphyxiant like helium or nitrogen, I remain skeptical that it is necessary to have a regulated flow as suggested with exit bags and pph protocols in order to "flush co2". Once consciousness has been lost, hypercapnia seems no more an issue than a surgery patient worried about the pain of surgery after being rendered unconscious. It's generally meaningless. Hypoxia is by no means a light sleep, and is more akin to a coma. I'm not suggesting you are saying that - only that the big bad co2 boogeyman seems to be widely misunderstood here by others. Attempting to just pass out with a bag over your head of plain air certainly could present problems depending on the substances being used to initiate unconsciousness, for example barbiturates in overdose eventually paralyze the breathing system - other substances that are gaba-a channel agonists like etomidate do the same. BZDs are gaba agonists but more effect the limbic system, although I suppose the possibility for re-arousal is highly dependent on the dosage taken, just like opioid agonists. I mean, an overdose of a highly potent opioid is not going to put anyone at risk of hypercapnia, regardless of co2 concentration. The co2 would just kill them.

One could also use hand warmers as O2 scrubbers.
