Hydrogen sulfide is a potent gas more deadly than carbon monoxide gas where death occurs more quickly.
Strong Acid + Calcium Polysulfides solution -> Hydrogen sulfide (H2S)* If in a bathroom or a car,enough with each 2 litters (about half gallon).* You can use sulfuric acid of a car battery as strong acid, and you can use a pesticide lime sulfur as calcium polysulfides.It reaches a fatal concentration over 1000ppm quickly, Please mix in a vessel, such as buckets. If done properly consciousness should be lost in under two seconds and the entire process will be painless. Mix in a small **airtight** location for best results. Leave warning signs around the area for first responders.Acid Sources:
**The Works(R) Toilet Bowl Cleaner (15-25 percent HCl)**Lysol(R) Ready to Use Disinfectant (4-8 percent citric and hydroxyacetic acid) Lysol(R) Toilet Bowl Cleaner (9.5 percent HCl) Sno Bol(R) Toilet Cleaner (15 percent HCl) Blu-Lite(R) Germicidal Acid Bowl Cleaner (20.5 percent phosphoric acid) Kaboom(R) Shower, Tub, and Tile Cleaner (5-7 percent urea-monohydrochloric acid) Tile, stone cleaners (1-30 percent HCl) Sulfur Sources:
**Pesticides (5-30 percent calcium polysulfides)**Artist oil paints (0-15 percent zinc sulfide) Dandruff shampoos (1.0 percent selenium sulfide) Spackling paste (1-2 percent zinc sulfide) Some latex paints (6.6 percent zinc sulfide) Garden fungicides (5-90 percent sulfur)
Does mixing toilet bowl cleaner and shampoo give hydrogen sulfide?

Does anyone know the chemicals A person needs to buy in order to commit suicide this way?

As everyone else has said, this method is a very bad idea.

It's also worth considering the innocent victims often caught up in its wake...

You can probably get hydrochloric acid from something like home depot as a cleaner for that white stuff in washing mashines, my Sulfude source was lime sulfur, widely accessible in the us, can be ordered as lime dip everywhere else in the world

Why would you want to inhale hydrogen sulphide gas? Thats what this shit method is, bath salts and toilet cleaner pretty much. At low levels hydrogen sulphide gas causes irritation of the eyes, nose, and throat. At moderate levels symptoms include coughing, dizziness, headaches, nausea, and vomiting, difficulty breathing and finally at higher levels shock, convulsions, coma & death. Not the prettiest way to CTB. You would be in immense discomfort & pain before passing out, is that how you want your last moments to be?

I have no idea why your talking about hydrochloric acid, as this chemical is not used in this method. Hydrochloric acid is extremely corrosive, you do not want to be inhaling or ingesting such a corrosive chemical. Stay away from this.

What @Lime doesnt mention in his post, which is a web conversation copied &pasted in from a report on Detergent suicides put out by the Massachusetts Sheriffs office is that 25% of people that die by this method are first responders to the scene. 25%...thats a lot of innocent victims in this.

Hydrogen Sulfide is formed by mixing two household detergents (thus the name detergent suicide). One of these is an Acid source, be it HCL or sulfuric acid, doesnt really matter. The other one is the Sulfur -2 source, not just plain sulfur in a powder form. This oxidation state of sulfur is found in various detergents like fungicide's etc. and also Lime Sulfur/ Lime Dip which is used to treat a form of pesticide on pets. Effectiveness of the H2S reaction is highly increased my using Hydrochloric acid, which is more concentrated than the 5-8% HCL you'll find in household cleaners

Please do some research before posting these statements. No offense. At lower concentrations (sub 500ppm) your stated symptoms are correct, but once the ppm gets above 700 (if you wait a few minutes before entering the room it'll be between 1000 and 2500 depending on your mixture) one, at max two breaths are enough to NOT pass out, but literally kill you. Its a matter of going in and inhaling. Be aware, it smells like wet farts like hell tho

No offence taken, but I am an MD & also hold a PhD (Pharmacology). So research is something that Im particularly proficient at & something ive spent a lifetime doing, so I think I am more than able to give an informed & qualified opinion on the toxicological effects of exposure to Hydrogen Sulphide. If you follow any reputable Medical Journal it will reinforce what I already previously stated, that at low to high levels of exposure (Im talking about 500ppm-1000ppm) there are an array of possible symptoms, some of which I have already described but include headache, fatigue,nausea,intense anxiety,mental disturbances,pulmonary edema,&respiratory arrest.
Research shows that 800ppm is considered the lethal concentration for 50% of humans following 5 minutes' exposure (LC50), so from this you can already see that there is significant variability in the population of those that have been exposed to H2S. The symptoms I alerted to earlier are just some of the symptoms experienced following low-high range H2S exposure. For some people, many of the symptoms ascribed to them occured at low level contamination while others only experienced symptoms at higher concentrations. Deaths have been reported in people exposed to concentrations of H2S below 400ppm, however people have also recovered from exposure to concentrations exceeding 800ppm. Hydrogen Sulphide is called a "knockdown" drug because at certain concentrations (which differ person to person), the person becomes rapidly unconscious or immediately collapses within a few breathes, breathing may stop and death in a few minutes. Interestingly on termination of exposure recovery can occur quite quickly, even after exposure to high concentrations of Hydrogen Sulphide, again thus the "knockdown" effect.

I destroyed my life using this method. My car, everything. Huge hospital bills. Don't do it. I couldn't taste anything for weeks either.
I'm sorry to hear this- thanks for sharing your results, and hopefully things can get better.

i drank just a tiny bit as an attempt a year ago, and i felt a slight headache. I think it would be very painful and not even lethal if you drink detergent.

Yes, the idea is to combine chemicals and inhale them- but there is still not a good way, very high risk of damage and not ctb.

Thank you. So you'd seal the car and do prep work with warning signs inside and around, then quickly mix the chemicals inside a bucket in the car, shut the door, wait outside for the hydrogen sulfide gas to increase to 800-1000 PPM, and renter the car while holding your breath until taking a final few breaths.

I think I saw a video from the San Diego firefighter or hazmat department that showed it can reach 1000 PPM or kill within 9 minutes when only using 32 oz, but that's not fast enough. Use 96 oz and it takes 6 minutes.

The violent chemical reaction they showed means using more than 96-128 oz (128 oz is a gallon) of both chemicals would highly increase chemical burns as the liquids react. I wanted to use 256 oz, but after research I see that's too much.

96 oz seems optimal. Just mix the chemicals from the passengers side then shut the door. Problem solved. All done at night in a remote place.

I'm in research mode. Good information is scattered across the web even from 15 years ago. If someone finds this thread, I wanted to note they don't have to sit in their car in pain while waiting for the chemicals to achieve +700 PPM for a faster death.

Well, being that you're kinda new here, don't be surprised if your suggestions, recommendations, etc don't end up carrying much clout with other users. And, if you really wanted to provide some guidance to others who might find this, or other, related threads you might also mention that H2S is ANYTHING OTHER THAN a peaceful method. In fact it is a quite HELL-ISH method. There's nothing comfortable about dying that way. If you want to put facts out there for people to consider, put ALL THE FACTS out there, so that they can make a TRULY INFORMED decision.

I'm not an expert or clout chaser. I'm sharing what I've found as I'm researching. I'm also not providing guidance. Anyone considering suicide must research as much as they can and not take anyone's word as gospel.

Until I read that person's comment, I assumed I had to sit in the car until lethal levels were reached. That person likely saved me from needless suffering if I sat inside my car waiting.

I'm trying to reduce experiencing pain. Leave me alone.

That's really rich. First, there isn't anyone picking on you. You come in here like a bull in a china shop, new member, first day, and don't even bother to interact with anyone in current threads. Immediately, you head right to old postings and, somehow, find five-year-old postings about N2S, without even having the benefit of a search function to find them, mind you, and then post in them like your word is gospel. It's actually kind of uncanny how you even knew there were threads on N2S, being that you are (supposedly) a new account just started today - I'd really like to know how you even knew there were threads on H2S and where to find them. But, I digress. Your post had lots of facts, numbers, this, that, and the other. That's all well and good. But, then someone reacts to what you wrote and gives you a mild "suggestion", but that only begets nothing but a defensive posture from you, along with chastising that you're being picked-on. And now you seem to indicate that you want to absolve yourself of any responsibility for what you write ("Anyone considering suicide must research as much as they can and not take anyone's word as gospel"). In an ideal world that would be great, but it really doesn't always work that way. Many are unable to do in-depth research themselves and take what they read as gospel. Maybe everyone, including myself, is a little on edge right now because of the current goings on, but, as of right now, I got to say that you make it really easy to be suspicious.
