So, I have been doing a little research all over trying to figure out the positives and negatives of each inert gas and how to convert the cannister to a medical gas mask or the bag method, can anyone give me a reason why people have started moving away from inert gases such as helium and nitrogen? what are the risks of doing it this way?

Perhaps it's a question of convenience, a lot of people don't have the time or place to set it up without raising eyebrows.

Probably the technical aspect ( and in some case $$$ )

Personally I think inert gas like Nitrogen in combo with scuba mask comes as close as possible to N as it can.

There is always a risk of failure in every method. The inert gas method has many advantages, its reliable and painless. But it requires technical ability, equipment purchasing like gas tank and regulator+flow meter and assembling the exit bag. Most people that are considering CTB dont have the time, money and energy to learn how to set up a proper inert gas system. Varying on location it should cost several hundred dollars.

Could you explain some of the risks of failing? The only prominent one I could find was brain dmg from the hypoxia other than that it seemed more surefire if you had the time and knowledge it set up right .

Do it wrong and you could end up as a vegetable, disabled, brain damage ect. All can be avoided if someone does it right but the risks will always be there, even if theyre very slim. Theres lots of research required for the method, its also expensive and very hard to get pure helium now- as for the other gasses (atleast where i am) one would have to go in store and come up with a story about how they need a tank of nitrogen for industrial purposes, i would definitely make a fool out of myself which is why i decided to just get nitrous instead. Cheap and i just ordered online- alot of people dont know about that one. I think gasses are intimidating to people because of the risk of failure and the amount of extensive research needed. However if you do it right you get a 100% peaceful exit, i would much rather this method in comparison to SN, but with SN the reliability is pretty much 100%- which is why people tend to stick with it.

that's a fair point, I haven't considered SN, I'm relatively new so I'm assuming that's sodium nitrate? is that difficult to obtain like helium?

sodium nitrite, it depends what country youre from- im too worried to order it because theres been many posts about getting welfare checks and getting sent to hospital after ordering it. The site is also a bit hard to find. 100% helium will be hard to get, there are other inert gasses that are easier to get.

I was thinking of using Nitrogen gas as a primary just because I could disguise it as using it for cooking. Are there any "non suspicious" reasons you would have SN? I'm not exactly knowledgeable on chemical compounds but I am relatively for gases

Someone could probably say theyre using it for meat or cheese curing? I would check the laws in your country first though, its banned in some countrys and you could get in legal trouble. i also recommend putting "sn" and "your country" into the search bar here, see if theres any reports of getting welfare checks or trouble getting it.

That's a fair point, it doesn't seem to be banned nor reports I guess where I live it's an extremely uncommon method which is why I wasn't familiar with it, I'll have a look into it a bit more but do you have any advice for searching for the topic or have any threads/info to share?

Nobody is moving away from Inert Gases, there is no risk with Nitrogen and the EEBD Hood, as long as your connections are secure--

Agree.
There are so many industrial accidents involving inert gases that we dont hear about them. And that is just open exposure....not involving a hood, mask, etc.
There are ways of doing an inert setup that is efficient. Almost all the supplies can be obtained from Amaz.

Failing can lead as said to all kinds of brain damage. The reasons for failing is not having enough gas, having lower gas flow then required, having to much flow that can blow the exit bag off the head, gas tank not pure enough and contains oxygen, convolutions after you loose consciousness that may cause the pipe or exit bag to come off the head, and of course the notorious survival instinct known as SI that needs determination to get over but its lower in this method than in others.
For me it was very easy to get the gas tank, I just contacted a welding shop and asked for a Nitrogen tank, I wasn't asked a single question. I picked it up from the shop and later called to ask how pure it was and they said it was 99.99% Nitrogen. I think its much easier and cheaper to get than pure Helium.
I acquired knowledge during few months, the equipment took few weeks to get, I've constructed 3 different exit bags, and I'm very confident in my system.
I plan to do it in my car at night at the forest near where I live.

one of those accidents happened a few weeks before the first launch of the space shuttle in 1981, killing two people on the launchpad and causing brain damages to a third:

Here is a hypothetical hood setup using a an industrial safety hood.
This industrial hood is used for this exact situation...except it uses breathable air....

These respiratory hoods use air compressors to give an air supply under pressure to the user.
The air compressors used with these hoods have an output of about 2-12 psi and up to 20 cfm.

This setup is the same for ctb purposes...since the gas from the cylinder is also pressurized.
Actually the cylinder is at a high pressure than any air compressor could be...they are usually at 2200 psi....hence the reasons for a regulator to drop & control the output pressure/flow.

The best al around resource is the PPH (Peaceful Pill Hand book) that has all the details from a medical and technical point of view, page 129:
https://gofile.io/d/W0Zwnc
Exit bag diagram: (scroll down to the mechanism section)
https://en.wikipedia.org/wiki/Suicide_bag

Also some good posts by SanSui members include detailed photos of their systems:
https://sanctioned-suicide.net/threads/leaving-in-an-hour-goodbye.187099/
https://sanctioned-suicide.net/thre...ng-together-a-nitrogen-exit-bag-setup.187337/

My own system with out the exit bag:

What I bought (I'm not from the US so I converted to USD):
For gas flow:
Nitrogen tank containing 600 Liters ($140)
Regulator + Flow meter that connects to the tanks threading ($55)
Pipe for Nitrogen flow from flow meter to exit bag (2 meters) ($5)

For Exit Bag
35x50 cm Oven bags for assembling the Exit bag ($1)
Porous tape for taping the edge of the bag ($1)
Elastic underwear rubber band ($1)

For calculating the volume of the Nitrogen compressed in the tank you need to know the volume of the tank and the pressure. You can read the pressure from the regulator/flow meter. The recommended flow rate by the PPH is 15 Lt/min for 30 minutes. That requires 450 Liters of Nitrogen.

Thank you so much. I am planning to combine hanging and inert gas method. I naturally worry a lot. So, i like to know if there is a risk of explosion of the pressurized cylinder (i know inert gas is non-flammable, but worried about pressurized cylinder ) if i open the valve fast or if the cylinder falls.

The cylinder it self is very durable. The main concern is the valve at its head. If the cylinder falls and is hit at the valve it can tear of and release gas at once which is kind of an explosion. The gas by itself is non flammable. If you choose an exit bag I cant see how it can be combined with hanging.

i mean using gas mask and not a big hood. When i loose consciousness, the rope will do the rest. I am worried about the discomfort / pain of the rope pressing on my throat. I know that inert gas alone will do the job, but in extremely rare cases, the person may tear the hood or the gas may leak. I want to make sure that the attempt is 100 percent successful.

Have you seen the n20 (whipped cream bulbs) method?? Its much simpler and can be done with balloons or a mask, you can get the little whippets off amaz or eba.. I have tested and it works very efficiently to go unconscious, it gives me feelings of euphoria and pure peace. I personally am using it with drowning for no other reason then i think itll be less traumatizing but it would work fine with hanging too.

heres a few of my posts that may help, if you read all the comments aswell youll get a pretty good idea of how it all works :-)

most likely drowning, only because it will be less traumatizing to my family. Hanging can be gruesome.

Thanks for this visual. I've seen a bunch of your posts and I find them very helpful. I just ordered this hood with the adapter, I'm not sure if that was my SI saying I needed something more, but anyway it's on the way. Hoping my vinyl tubing fits on the adapter, I couldn't find its diameter. I'm just biding time anyway as I'm waiting for my lawyer appt which is sooooo far away (feels like). Anyway thanks again.
