I'm struggling to find SN so want to look into other potential methods and educate myself in case I never manage to get any. Nitrous oxide, I can get this easily on the clearnet you can get it in 2000g canisters and it comes with a pressure release nozzle. I've used it recreationally so maybe I would need more than someone who's never used it. I've seen a lot more in the news that people are actually dying from this I'm not sure if that's just because of long-term use, but I'm more hopeful that would work. Helium and Nitrogen I've also looked at and a lot of the canisters now are being mixed with oxygen. Making it unlikely that I'd actually die from it I'd probably just get severe brain damage then just being a vegetative state unable to try again. I'm not sure if they would be mixed with any oxygen. It just says for catering purposes. Would it be possible or would I need a medical grade?

Culinary N₂O is typically stored as a liquid under pressure (it occupies a significantly smaller space than pressurized gaseous N₂O would). Trying to add oxygen to liquid N₂O wouldn't make much sense (they simply wouldn't mix well). It's possible to create a mixture of gaseous N₂O and O₂ like medical Entonox/Nitronox, but it would occupy a bigger space and need a bigger cylinder/canister. Culinary N₂O canisters are commonly more compact than N₂/Ar/He cylinders of comparable capacity. 2000 g of N₂O contained in a 3.3 L canister expand to approximately 1000 liters of gas at the standard atmospheric pressure. 5 liters of N₂ at 200 bar (in 5 L nitrogen cylinder) would expand to nearly the same volume.

Food-grade N₂O should work well. To dispel all doubts, it's enough to hyperventilate with plain air for 10 - 20 seconds, then make a single very deep breath of N₂O and hold your breath for about 30 seconds. The effects will speak for themselves.

Ok thanks this all really useful information I've made note of it now. How long do you think it would take to become unconscious? I just know my survival instinct I could just rip the exit bag off. How long does it take for death to occur minutes - hours? I need to be sure that it will work.

That depends on how you breathe the gas. If you exhale maximum air before inhaling N₂O and then won't let significant amounts of oxygen to be mixed with nitrous and won't restrain your breathing, then loss of consciousness in under 30 seconds is very likely.

Possible effects of inhaling N₂O are well described in this book
https://i.sanctioned-suicide.net/im...t_-_Anaesthetics_and_their_administration.pdf (starting from p 243)
I just know my survival instinct I could just rip the exit bag off.
At least, you will feel happy ) So you win in either case.
How long does it take for death to occur minutes - hours? I need to be sure that it will work.
Likely in 10 - 30 minutes, unless you inhale nitrous with too much oxygen. N₂O is a simple asphyxiant that displaces oxygen from the lungs similarly to inert gases like nitrogen or helium, and the time to death from breathing oxygen-deficient gas mixture would be nearly the same in either case.

If one does this, they should, IMO, use a combination of tight rubber bands, electrical tape, and potentially a Velcro stretch-strap as well in order to prevent movements one makes while unconscious from disrupting the seal.

Plus, I would use two plastic bags to further reduce the risk of oxygen permeability (research indicates that some plastic bags are more oxygen permeable than others).

Further, some bags are sturdier than others, and you want to use one that isn't going to tear or be easily punctured.

Also, note that the bag in this case needs to be a lot tighter than the exit bag because there is no constant flow system to flush out ambient oxygen. It should, ideally, be virtually airtight, and it would be wise to perform tests beforehand regarding this.

This is my backup method, FWIW.

Wouldn't it be better to take repeated shallow breaths instead, rather than taking a single deep breath and holding it, because of diffusion hypoxia and the fact that hypoventilation exacerbates it?

I supposed that the OP is going to use a ventilated setup with some N₂O regulator. Purchasing 2000 g of nitrous for CTB with a sealed bag seems like overkill )

A single deep breath is supposed to give some impression about how N₂O can work when you still have a small amount of residual air inside the lungs, without elimination of oxygen that comes from the bloodstream to the lungs. If nitrous feels strong even under such imperfect conditions, this is a good sign. Checking the full strength of breathing pure gas continuously may be done in other test.

As for diffusion hypoxia, this phenomenon does not occur until you displace nitrous from the lungs with air.

You may be right, but they didn't specify what method they wanted to use.

The reason I brought up diffusion hypoxia is because of the fact that hypoventilation is known to exacerbate it. So, the question I have is would it be best to breathe in a shallow manner rather than taking a single deep breath and holding it in?
