Hey, I noticed over the last weeks that the same SN-related questions keep popping up, so I decided to research a little to answer most of these common questions and concerns.
This is also just so I can send the link to people and don't have to write a new response each time :D
How many people choose SN as a method:
From what I've dug up, sodium nitrite (SN) popped up as a suicide method around 2016-2018 when Exit International got more interested in it. Around 2018, online forums, especially SaSu, started megathreads on it, bringing it to attention globally. However, it's still niche but rising:
DO NOT TEST INGEST SN. Only consume the proper CTB dose if you are 100% sure you want to die!
sanctioned-suicide.net
How it works (med terms + simple breakdown):
Okay, SN is NaNO2, a salt that messes with your blood's oxygen game. In med speak, it oxidizes hemoglobin's iron from Fe2+ to Fe3+, forming methemoglobin, aka: Your blood turns into a brown goo and can't carry oxygen anymore. This triggers cellular hypoxia (cells starve for air even if you're breathing), leading to lactic acidosis, seizures, coma, and cardiac arrest if untreated.
Simply: Imagine your blood is a delivery truck for oxygen. SN jams the engine so oxygen can't get delivered. Your body panics, tissues suffocate, and everything slows until it stops. It's not like falling asleep; it's more like slowly drowning on dry land. (But you would most likely be asleep before the worst effects set in.)
Effects of SN with a timeline: (from both successful and unsuccessful reports)
This timeline was pieced together from autopsy data, survivor stories and SaSu threads, as well as my own SN test. It's messy because doses vary, but here's the average from 100+ cases:
How much is dangerous:
ld50 (dose killing 50% of folks) is ~71 mg/kg body weight, so for a 70kg person, ~5g is lethal half the time.
The average SN amount people ingested is usually 15-30g. Why is that? Anything over 1g can cause severe problems (methemoglobin >20% = danger zone). But for a reliable and somewhat painless end, it would make sense to ingest as much SN as possible in your bloodstream before vomiting it out. With high SN, your body rushes through all the stages of poisoning quickly and enters unconsciousness within about 20 minutes. Low doses kill, but it can be many hours of agony till you pass away.
The general formula is 250-350mg of SN per 1kg of body weight. To explain further:
There are a lot of reasons why SN works differently for everybody, but those two are the main ones:
If you have a high muscle percentage and/or are male, your body has more blood, which needs to be converted. Therefore, you need a higher dose, like 350mg/1kg.
If you are skinny and/or female, a lower dose will be sufficient, like 250mg/1kg.
Even then, everybody reacts differently to SN, and it is just an absolute wild card. It is very hard to figure out the right dosage to achieve the most peaceful CTB. Too much and the bad effects are stronger, too little and it will take longer for you to fall unconscious. Again: Don't try test ingesting SN to figure out your dosage. Just don't....
How people usually buy and ingest it:
Most get it online: industrial suppliers sell 99% pure as "nitrite salt" for $20-50 per 100g (eBay, chem sites, dark web). I won't supply you with links, but it is not hard to find a seller when using DuckDuckGo.
Be careful to buy Sodium Nitrite NaNO2 and not Sodium Nitrate NaNO3. NaNO3 is useless.
The go-to is SN dissolved in water (50-100ml), chugged fast. Fast on an empty stomach to speed up the absorption. Some recommend drinking with a straw to bypass your tongue and lessen the salty taste. There have been reports of people using delayed-release capsules and filling them with SN. This mitigates your body's ability to vomit the SN since it is only getting released past your stomach. There really isn't much data about it at the moment, but it seems to work.
Don't try to ingest SN rectally or via IV.
Rectally, it will burn your intestines and give you the worst diarrhea. IV, you will burn your arteries away. Both will be incredibly painful.

What other drugs and chemicals do people use with Sodium Nitrite?
To "ease" the process, people add:
What if I don't have Benzos?
Benzos won't help with your passing. They are just more of an experience enhancer, knocking you out quicker and helping with SI. Benzos in themselves aren't that harmful at all.
An alternative to benzos would be Melatonin, and/or some OTC Sleeping Pills.
With SI, create a comfortable and safe environment. Some people recommended dry runs where they just mix water with normal table salt, drink it, and lie down so they get used to the whole process, and it isn't as scary anymore. There are lots of calming teas, herbal meds, etc, that also help with anxiety. Technically, really strong smelling salts or ammonia can help rock you out of anxiety/panic attacks as well.
What if I don't have Meto (Anti-Nausea)?
It is generally unadvised to attempt without Metoclopramide (or similar meds like Domperidone) since you will have a very hard time absorbing enough SN into your bloodstream before you vomit everything out again. There are some OTC Anti-Nausea medications, but they are usually meant for car sickness or similar. They are not strong enough to fight against the SN-induced nausea.
How you can get saved after ingesting sodium nitrite and how it works:
If you regret your decision, an antidote exists! It is called Methylene Blue!!!
If you call Emergency Services, tell them on the phone to bring Methylene Blue with them. It is slowly getting more common for Ambulances to carry this antidote, but it is far from a standard, especially outside the USA & UK.
Methylene Blue reduces methemoglobin back to hemoglobin, restoring O2 flow. It kinda works like a reset button if given quickly.
Plus oxygen therapy, bicarb for acidosis, and activated charcoal if early. ER docs monitor methemoglobin levels.
Survival rate is ~80% if treated within 1h.
How much time do you have before nobody can help anymore?
Window's tight: 30-60 min post-ingest for best odds, after that, brain/heart damage sets in irreversibly. If methemoglobin >70% is left untreated, you're looking at 1-2 hours till death. If you call Emergency Services within the first 15min you have a near 100% save rate. Low doses give longer (up to 6h), but with high CTB doses, your time is very limited.
What will happen after my death, and how will the Police handle the situation?

How can I store my SN?
Keep it sealed tight in its original container. SN is hygroscopic, meaning it sucks up moisture like a sponge, so exposure to air or humidity can make it clump, degrade, or even react weirdly. Store in a cool, dry spot. Room temp's fine. Around 15-25 °C (59-77 °F), but no extremes like freezing or baking in heat.
Closed containers under normal conditions keep SN stable for many years.

How to handle SN?
Handling sodium nitrite starts with treating it like the hazardous beast it is:
Always wear gloves, goggles, and a mask cuz dust or spills can irritate skin, eyes, or lungs, and work in a super-ventilated spot to dodge any fumes. Even breathing in or touching small amounts of SN can lead to you having symptoms. Be very careful!

This timeline was pieced together from autopsy data, survivor stories and SaSu threads, as well as my own SN test. It's messy because doses vary, but here's the average from 100+ cases:
- 0 min: SN tastes like extremely strong seawater mixed with iron supplement powder, so a very salty, metallic and almost chemical taste. This taste will linger in your mouth for a long time and will irritate your throat and gums.
- 1-5 min: Stomach gets upset (nausea, cramps if no anti-vomit meds like meto, heartburn). Head spins a bit, like low blood sugar. Dizziness and confusion slowly set in. Some are starting to feel warm, like a mild fever
- 5-15 min: Skin slowly turns blue-gray (cyanosis), strong pounding and racing heart felt through most of your upper body and up to your head (tachycardia). Shortness of breath. Usually, at that point, anxiety spikes for most because you feel the hypoxia creeping in. "Air Hunger" can occur. Drop in oxygen levels often causes muffled hearing and tunnel vision.
- 15-30 min: Dizziness turns to fainting, seizures in ~20% of cases, muscle cramps, and strong vomiting start. Methemoglobin levels hit 50-70%, and organs start failing.
- 30-60 min: Coma for most successes, but survivors report burning pain, choking panic, or hallucinations. Skin turning chocolate-brown for many.
- 1-3 hours: Death from heart stop or brain swelling. Longer in low doses (up to 24h). Survivors report: permanent damage like brain fog or heart issues

What other drugs and chemicals do people use with Sodium Nitrite?
To "ease" the process, people add:
- Anti-nausea meds (metoclopramide)
- Benzos (xanax/Diazepam/Ativan) to calm you down and help you pass out quicker
- Antacids are used to boost absorption, but can lead to an increased seizure risk
- Weed to "relax" but often makes vomiting worse
- Pain Meds like Ibuprofen, Tylenol, or even Opioids like Oxycodone, Tramadol. Opioids increase the risk of vomiting, but can be treated with Antihistamines
What if I don't have Benzos?
Benzos won't help with your passing. They are just more of an experience enhancer, knocking you out quicker and helping with SI. Benzos in themselves aren't that harmful at all.
An alternative to benzos would be Melatonin, and/or some OTC Sleeping Pills.
