is there a difference in how long either of them take? i know sn takes about 30mins to an hour, but im not super educated on the cm method. i also know that sn can make you very uncomfortable and sick and potentially causes seizures, and both methods are a form of suffocation. i want to ctb in the least stressful way possible since im super prone to panic attacks. i feel like si would be a problem if i were to use the carbon monoxide method.
also off topic question, but does sn expire? im thinking about purchasing it but i dont want to be too scared and wait too long and let it expire.
also which charcoals do i use? car exhaust fumes??
edit: oops i just saw the cm megathread pop up so ill read about it. just wondering the similarities and differences between both methods

I'm not comfortable giving specific advice. I can only talk in generalities. Plus I am not overly/deeply educated about SN or CM. I can say that SN is difficult to obtain unless you know the elusive dsl Web site. I've searched every way I know how and I can't find it. Modern cars no longer produce enough CO2 to do any damage and haven't for a long time.

ik ppl are able to find DSL it just takes a lot of looking and kinda losing your mind before you can find it. apparently its a rly silly looking website. i havent tried to look for it myself yet, i kinda wanna be super sure of my method before i do. but thank you :)

No problem. Believe it or not I am not looking to CTB right now. I signed up for this site because I am concerned about long term career security (I don't want to get too specific) and I want to have a way out planned in the (hopefully unlikely) event I need to. It has to do with my anxiety. I came here and found a good community. I hope your life gets better. Sending you a virtual hug and positive thoughts. I had panic attacks a long time ago and they are horrible. I can relate.

im honestly kinda in the same boat! i have a bunch of stuff that causes my panic attacks, but im honestly not looking to ctb anytime soon hopefully, just trying to lay out my method if i choose to. anxiety always makes you wanna plan ahead just in case, i totally get it. sasu is such a great community <3

all depend on the concentrations of cm there is forum posts about effects based on concentration

I'm considering both methods, once they're ideal for enclosed environments and have high lethality rate, so here are the cons of each other I know:

SN:
. Difficult to obtain in certain places;
. Requires antiemetics and fasting.

Carbon Monoxide:
. Requires a CO meter up to 10.000ppm;
. Takes some time to produce the amount needed to ctb.

. Requires a CO meter up to 10.000ppm;
If carbon monoxide is produced in a nearly pure form by means of some decent lab method (f.e., via decomposition of citric acid by concentrated sulfuric acid) and inhaled after moderate dilution with air, CO meter is not needed, since the setup can offer a guaranteed highly lethal concentration (over 100k ppm).

If you're considering CO instead of SN, there are many other methods available. The reason people in this community prioritize SN is quite literally because there are no aftereffects. If CO fails, the consequences are devastating, and there is no turning back.

Aren't they basically the same process with the same aftereffects?

Yes how are the after effects different from CO

I think you got this wrong. There are multiple people here that got very close to death whit CO confirmed in the hospital that got no aftereffects and majority of them failed because they got found. Some retried the method after a while and passed. Same for SN.

This does not mean that you should ignore proper preparations if you try to attempt but I read a lot this forum in the last few months and I cannot confirm this post.

Honestly don't know, but the reason CO is not a good option is because of how risky it is. I wish I had SN.
The only real risk is if other people are around.

SN does not require antiemetics. It's only a recommendation to add to the protocol.
How much SN is required for it to work

The problem is that you need CO to be around long enough to make sure you don't wake up. If you fail this method you could get brain damage

Ahh I see, I mean there are people on here who attempted and survived with minimal damage but I'm not taking any chances, that's why I'm combining carbon monoxide poisoning with hydrogen cyanide poisoning. Hydrogen Cyanide is 35 times more lethal than carbon monoxide and when combined they have a synergistic effect that causes a near instant loss of consciousness and quick death.

How did you get hydrogen cyanide?
