Suggestions on dry ice?

[Life'sA6itch]

I think it could work. I could line a bathtub with a massive plastic bag, seal it while inside and wait.Takes some prep, it's not impulsive or as convenient as downing some pills etc. Some may prefer taking a relaxant of some type while others may find they don't need that. Case in point: https://www.cnn.com/2018/08/01/health/dry-ice-death/index.html

Seems it overtook these unsuspecting women in seconds to just a very few minutes.

IG, citric acid & baking soda would be commonly easier to obtain than dry ice. And, unlike dry ice, they can be easily stored for an indefinite time. So I'd rather prefer the acid + soda method in case of resorting to CTB via CO2 poisoning.

I'm curious, what is IG?

What if you just buy a gas bottle. CO2 is available everywhere. That said, nobody should use CO2.

That seems more complicated for me if it requires a regulator, etc. I'd prefer helium if I was looking for tanked gases. Really want immediate lights out & to never wake again.

IG = I guess

I haven't seen anything like that available outside of specialized shops in the place where I live, while citric acid and baking soda can be purchased in many offline supermarkets and shops selling common household chemicals.

It'd better use CO2 than NaNO2 or NaN3.

That seems more complicated for me if it requires a regulator, etc.

There is no need in a regulator for filling a plastic bag with CO2 from a tank. CO2 is a chemical asphyxiant that works differently than inert gases. It causes rapid unconsciousness at concentrations 30% or above, which are easy to achieve in a sealed plastic bag without maintaining constant gas flow in a manner of popular CTB methods involving inert gas asphyxiation.

Carbon Dioxide: A Simple Asphyxiant?

that is to say ? why ?

 

[Endofpain]

that is to say ? why ?

CO2 is responsible for our urge to breathe. The body reacts to a slow CO2 buildup with panic and rapid breathing.

yes, that's hypercapnic response ! but if a 100% co2 trigger loss of consciouness in less than 10 sec, it not so painfult than any other method !

citric acid plus baking soda? i never heard about this, can you elaborate please

The reaction is demonstrated in the video below

View attachment Citric acid + baking soda + water reaction.mp4

A known example of successful CTB via CO2 obtained with the reaction between baking soda and citric acid is described in this report

https://i.sanctioned-suicide.net/images/2025/03/222942_CO2_death_case_report.pdf

I'd rather prefill the plastic bag with CO2 before putting it over the head instead of carrying out the reaction inside the bag placed over the head.

I use this method to euthanize deformed or struggling chicks. Baking soda and vinegar

Vinegar is acetic acid, which is a volatile irritant. Inhaling a mixture of CO2 with fumes of acetic acid may be more unpleasant than inhaling CO2 alone. I'd advise to use non-volatile acids for producing CO2. For example, citric, oxalic, and sulfamic acids are water-soluble powders that do not form irritating fumes before or after dissolving them in water.

Wow I'm glad I haven't done this in a really long time. I didn't know that. Now I feel fucking awful

Everyone assured me this was the most humane way. Fucks sakes!

how fast do they "go out" from that? you just hold them above the mixture? so the point is to inhale it?

It's usually quick if I get the lid on tight. I put them in a medium sized Tupperware on a towel, and then have the baking soda in a little cup. I pour the vinegar into the cup and immediately close the lid. Usually within a minute they're gone.

and the exact same thing would happen to a human? obviously not inside a tubberware lol, but you know...

Theoretically I suppose so. You would need a very small enclosed, fully sealed space, and A LOT more than a cup of the concoction. I don't think I'd advise this as a method though, especially after the post above saying it's very painful done the way I have to my chicks.

There's too many variables here that it's just not a good idea, at all.

Plastic bags are well suited for this. They're good for H2S and CO poisoning as well. Perfect seal is not necessary, because cessation of breathing due to CO2 poisoning occurs in 1 - 1.5 minutes. After that, any gas exchange between the inner and the outer spaces of the bag wouldn't matter. If artificial ventilation is not carried out shortly after respiratory arrest, the chances of survival become very low.

and A LOT more than a cup of the concoction.

90 g of sodium bicarbonate and 200 g of citric acid should suffice for making 10 liters of CO2 in a reasonably low time. This is enough for CTB with a plastic bag.

There's too many variables here that it's just not a good idea, at all.

The only significant variable, besides determination and carrying out the method in an adequate way, is tolerance to suffocation for the period before LOC )) Once this hardest part is completed, the chances of successful CTB are probably better than from inert gas asphyxiation.

Of course, there are much better methods in terms of comfort, but this one belongs to a somewhat unique category, as it uses just common household chemicals and it's relatively simple in preparation, very deadly for the suicider and safe for the first responders at the same time.

I never even thought of a plastic bag! D'oh!

This is actually not a bad setup at all for someone who wants to go quick and doesn't have access to a lot of supplies. You should post a thread of this as a potential method!
