Method Nitrous oxide gas (whipped cream charger) method

[kitchenwindow197]

Does anyone know much about this method?
Its much easier and cheaper to get than nitrogen or 100% helium, im thinking that i could use it with either drowning or hanging-

Drowning
What im most worried about with drowning is that ill be found before im dead washed up or something (also the beaches are very crowded here so i would have to do it at night), would it work in a bathtub? I would breathe in the N20 to lose consciousness and then simply pass out and hopefully die? Foolproof?

Hanging
With the hanging i feel that its more reliable but it will be more traumatizing for my family, ive done heaps of research on hanging and know exactly what to do but im mostly worried about the impact on whoever finds me... I wonder if putting a note under the door as a warning to call the police could fix this problem??

Exit bag
Ive also thought about using it exit bag style but does the gas have to be flowing? Or would i be okay to simply use a large trash bag and duct tape it around my neck?- ive read case reports of people who died that didnt have flowing gas but how much less reliable is this? Dont want to be a vegetable

I think drowning is best. No setup required, not visible to passerby once you're submerged even if there happen to be some at night/in the early morning, impossible to survive unless you are found or you somehow wake up due to increased cerebral blood flow from the compensatory response (unlikely given severe hypoxia as O2 levels will plummet), which becomes progressively less likely as submersion time increases - meaning ostensibly low risk of brain damage from it, so you could just attempt again.

It's probably too tricky to do in a bathtub. How would you ensure that your neck was weighed down at just the right time, for instance?

Vacation rental with private indoor pool would be ideal (as long as there are no hidden cameras), but it's almost impossible to find.

Ocean will increase chances of washing up on the shore.

All in all, IMO, the best option is probably a lake or river. Don't do it too deep because the chance of waking up will be higher due to pressure increase. And don't do it in cold water because you can be resuscitated for longer.

Okay thank you! Im trying to think of somewhere to do it but i live in a sort of popular area so it will be hard to find a hotel at short notice, also dont want to traumatize any members of the public. I can think of a few canals that go into the ocean, maybe thats my best bet. Funnily enough im worried about a possible shark attack while im in the process of going unconscious- Ive seen so many sharks at night in the canals. I also know of a lake i could use but again, i really dont want any children/families to see my body floating around.

I could tie a weight to my neck and kneel on my knees in the bathtub so when i go unconscious theres no chance of me rolling over or anything.. Do you think that could work? Otherwise i might go with the lake option and hope there are no late night fishermen or something

Depends what kind of sharks I guess

You want somewhere with minimal foot traffic. Maybe you could drive out a ways?

I don't know how you would guarantee that you didn't hit your head once you fell unconscious, especially with a weight tied around your neck. You'd have to time it just right by submerging your head once you felt dizzy. There might be a way around this (maybe an air pillow, though I don't see how this could work unless the rope attached to the weight was rigged such that it would become shorter once the pillow deflated. Too complicated) that I simply haven't thought of, though. Anyway, seems risky.

theyre bull sharks so its probably too risky.
The annoying thing where i live is that pretty much anywhere with water is going to be filled with people, even when driving out an hour-ish. Ill go look around for some spots that people dont go to at night and hope i get lucky.
I was thinking of booking a remote place to "camp" that has a creek or lake, that way i can make sure i will be alone at night- i think it might be my best option

Dear Kitchenwindow107,
I'm presently pondering your question on the Exit Bag. I'm setting up all my ducks in a row for this method. I have the regulator and flow control combination. This morning I opened an account with BOC gases and discovered the price of a D size bottle is $197au from the depot plus rent. A D size cylinder holds 1.7 cubic metres of N2. From this I suppose a low flow rate from a fully purged oven bag with and elastic band to seal around the neck and delivery tube would only need a maintenance flow to maintain gas purity. Oh, I have also gone down to the Post Office this morning and loaded a $500au MasterCard gift card to make the N2 transaction with BOC Gases. My next test is to get the elastic and bag /tubing apparatus then, waste a bottle of gas and time record running a couple of CFM/min into the bag to keep it inflated. Once all that is tested, I'll get a gas refill when I'm ready to go. I'm awaiting heart valve surgery and that goes ok, suicide is delayed but prepared. I like to be prepared and that is 'suicided delayed' thus, I'm in full control of my destiny. As an aside, I tried every which way to post equipment pictures and no-matter which format used (under 2mgapixel) the SanctionedSuicide site would not allow me to post.

feel free to message me, id like to talk to someone who is planning something similar :)

Today's whip cream containers also have oxygen in them so they won't work.
You can get large canisters of 100% nitrous at a welding supply shop. Its also used in performance cars so an auto shop would have canisters.
As far as lethality, I'm not sure. I've gotten high on it years ago & it didn't seem like it would be deadly to me.

I dont mean actual whipped cream, im talking about whipped cream chargers that are 100% nitrous oxide haha!
The high on nitrous oxide is apparently amazingly euphoric, its the same stuff as laughing gas so it should be a great way to go

 

[Intoxicated]

That's very unlikely, because the presence of high amounts of O2 would significantly reduce the quality of whipped cream. The brand of the chargers I purchased claims 99.95% purity of their N2O and warns about possible hypoxia in case of inhaling the gas. A single deep inhale of nitrous from one 8g charger was enough for making me fainting, so it works for sure.

The high on nitrous oxide is apparently amazingly euphoric, its the same stuff as laughing gas so it should be a great way to go

I suspect that you'd have to inhale a lot of N2O to achieve somewhat intense euphoria. I never got "very high" on it, since I used only small doses, but its ability to lift the mood is great. N2O can work as rapidly acting antidepressant, so even if you change your mind about using it for CTB, you can find this gas useful (only rare use without provoking severe hypoxia can be safe, because nasty adverse side effects can be produced otherwise).

One more thing: I would use a weighted vest if I did this

Sealed bag should work fine if you ensure ≤25% air and ≥75% N2O (keeping in mind that the lungs initially contain some amount of air even after full exhale), the seal is good enough and the bug is not easy to tear. The critical proportion of air to N2O at which achieving a relatively fast loss of consciousness and insensitivity to stimuli is still possible is nearly 30% air vs 70% N2O (I wouldn't count on this, because some extra amount of oxygen is taken from the blood).

Something to note is that the can can freeze and burn you.

 

[SchrodingerIsDed]

I had an ex girlfriend who tried to ctb in the bathtub via drowning. It did not work. I don't think that would work very well. She survived plenty. I cannot fathom a drowning death.

The note with the warning could help, yeah, but people, especially family members, will want to verify. And it will spook them and they'll want to save you as fast as possible and make sure they do everything they can. They're not just gonna go, "Oh, okay, meh." They'll burst into the room and cut you down.

The gas has to be flowing, and you need the tank and a regulator on top which is pretty pricey. Couple hundred bucks. Also you need an open bag at the bottom, I thought, and the hose needs to go in at a very particular angle, because as you breath out, the CO2 needs to leave the bag, and be refilled by the nitrogen. Moving around could ruin the attempt. Seems complicated.

You only need the whippets and balloons- i have trialed it and after learning the proper technique i dont have trouble losing consciousness. Once you lose consciousness and slip under the water your brain is no longer being oxygenated and the chance of waking up underwater is incredibly slim- even if you did i doubt youd be able to process pain or whats going on before you fall unconscious again

Ooooooooo. That makes a lot of sense. I see what you're saying. Have there been success stories like the studies with sn? I reveal my ignorance, apologies.

Its not as known about as other methods but theres 2 case reports i found online about suicide with N20
1 guy inhaled the n20 and then used plastic wrap over his mouth and nose
A woman used n20 gas in a bathtub and taped a hammer to her head to keep her down
There was another case (unsure if suicide) where a man drowned in a spa after inhaling n20.

its sad that not many people know about it because it truly is a painless, cheap, and reliable method

It's likely that CO2 won't cause any serious troubles if you pass out from nitrous oxide. N2O is known to reduce sensitivity to hypercapnia even for conscious people. This is why there are high chances of completely sealed setups working well.

They have those big cans of n20 now that you don't need a balloon with don't they? Galaxy Gas.

It sounds good I just wonder how long do you stay unconscious with the n20?

What I don't understand is how you would seal it completely. Tape does not seem secure enough, nor does Velcro, so what could one use to provide an airtight seal that would hold up in the event of movement?

i would personally still use a balloon because of the risk of freezing your throat closed or the valve coming loose and the air over-inflating your lungs, but you could probably use a mask attached to it. Im pretty sure the unconsciousness lasts around a minute (give or take some) but i saw a post on reddit where someone was unconscious for 45 minutes

Isn't the Galaxy Gas designed specifically to use without a balloon though? It's not the regular canisters, it's built specifically to inhale.

im not sure i dont think its in my country, i wouldnt inhale straight from a tank regardless though. It will work as long as its pure n20

Well, by "completely sealed" I mean that the method implies the absence of a somewhat substantial exchange of gases between the inner volume of the bag and the outer atmosphere. Small leaks should not present an issue. Some people die from plastic bag suffocation even without trying to accomplish airtightness. For example, take a look at

https://i.sanctioned-suicide.net/images/2025/02/221416_Plastic_bag_suffocation.pdf

The column "Circumstances" in Table I of the document linked above frequently mentions "Bag untied" or "Bag unsecured".

Here's an example of fatal asphyxiation with nitrous oxide & plastic bag >> NSFW
Again, the bag appears to be not secured at all.

Chapter 19, "Self-Deliverance via the Plastic Bag" (pages 90 - 95) of the book "Final Exit: The Practicalities of Self-Deliverance and Assisted Suicide for the Dying" (1991) describes how plastic bag suffocation can be used in combination with fast-acting sleeping pills. The author doesn't seem to be very concerned about achieving strict airtightness.

Why wouldn't smaller leaks matter? If they occurred early on in the process and caused O2 levels inside of the space to rise above the 6% threshold, it seems like it could be an issue. We care about leaks for the exit bag, so why not this? It doesn't make any sense to me. However, even if death occurs because of CO2 levels, leaks still matter, as the rate of gas exchange could become too high for CO2 levels to remain lethal.

Sure, some people die without ensuring air tightness, but this does not establish that the method is reliable because we can't know how many failed with the same approach (although, it's worth noting that in fact many people have failed to CTB with a plastic bag). For instance, many people have died from overdosing on benzos and/or alcohol even though they are not reliably lethal in the majority of cases. Many people have died from exsanguination after cutting, even though it's widely acknowledged (here, at least) to be an unreliable method. Or take partial hanging - notoriously hard to get right because of anatomical variability (among other factors); it appears easy and reliable precisely because we see those who were able to do it successfully. It's just reverse survivorship bias at play.

I'm aware that authors like Humphry are not concerned about it, but, again, I don't know what this proves. They have IMO failed to substantiate the reliability of that method anyway (Boudewijn Chabot, for example, discusses this).

 

[Intoxicated]

Why wouldn't smaller leaks matter? If they occurred early on in the process and caused O2 levels inside of the space to rise above the 6% threshold, it seems like it could be an issue.

The more you inflate the bag with N2O, the bigger margin for error is. For instance, if you initially have 38 liters of pure N2O and 2 liters of residual air in the airways and the lungs, you need to replace 8 liters of N2O with air there in order to reach 75%/25% ratio between N2O and air. When you pull the bag over the head, N2O is partially displaced from the bag and streams of this gas should significantly reduce flows of air going into the bag. You have to do manipulations with the bag in a very negligent manner in order to allow >8 liters of air coming inside.

6% of O2 and below are commonly sufficiently low for producing unconsciousness and death quickly, but 6 - 8% are also known to be causing LOC and death, just after bigger time intervals. If you fall into unconsciousness when the concentration of O2 is below 6%, you likely won't wake up when it goes up to 8%.

With the total volume of 40 liters, 2% of extra O2 correspond to nearly 3.8 liters of fresh air. If you allow this amount entering the bag after it was sealed, this is not a small leak.

We care about leaks for the exit bag, so why not this?

I don't understand why someone would care about leaks in PPH-like exit bag which is supposed to be open by design.

Sure, some people die without ensuring air tightness, but this does not establish that the method is reliable because we can't know how many failed with the same approach (although, it's worth noting that in fact many people have failed to CTB with a plastic bag).

If strong airtightness were of big importance, I'd expect the ratio of successful attempts with unsecured bag to successful attempts with secured bag to be somewhat smaller than 7/11.

I think, the best way to prove that sufficiently good airtightness is feasible is to carry out a real experiment. A plastic bag is filled with a very small amount of air, put over the head and sealed with 3 - 5 circles of PVC electrical tape. After that, a gas with a low odor threshold (such as SO2 produced by burning several matches) is released nearby. If there is a substantial leak, we should be able to perceive the specific odor after 1 - 2 minutes of breathing inside the bag. If the gas smell is not perceived, the seal may be deemed airtight.
