Hello, Im new here. I think you get this very often and i hate to intrude but if anybody can provide some advice i would really appreciate it. In advance i'm going to say i did read the entire CO megathread but there is still some stuff i wasn't sure about. I'm going to dump bellow all the things i am not sure about/open to advice.
-Are disposable charcoal grills fine to use? From what i've read they contain around half a kilo of charcoal and they are easy to use. If the answer is no then this could be adapted but it could save me money and effort. Once again if the answer is no please suggest alternatives.
-I seemed to encounter most suggestions being either a tent or a car. I dont own a car and with a tent i worry some air could escape. My idea though is a small bathtub in my place that i would seal, most likely with some plastic sheeting/anything that will effectively airtighten it. For my purpose i would be using 3 disposable charcoal grills in around 1 square meter of room (inside bathtub). Is this possible or should i avoid this? If the answer is no, please suggest how to airtight a tent or other option.
-from what i've seen opinions are divided if its better to let the CO build up before entering or entering with the coal. I plan to enter with the charcoal, the only thing i worry about is if maybe the possible headaches or dizzyness could trigger SI? I could surely handle a headache or dizzyness but what if my body fights and tries to get out of the space?
-I live with my mom but i would obviously choose a time when nobody is home. I also live with two pets. My worry is, could the CO from the bathtub escape and poison somebody else? I would surely put a warning sign on the bathroom door, and open windows everywhere else. Is it realistic i might affect others or am i overthinking?
-thats about it. Any extra advice about this method?

I Thank in advance to any useful response.

-Disposable bbq's can work, but i think good quality briquettes or lumpwood charcoal are better options, and recommended in the megathread. I've bought 4kg Weber briquettes, as Zanexx succeeded with these, and i plan to follow the same timings, so using the same brand seemed best.

-I'm no expert, but the plastic sheeting/bath sounds dangerous to me. Zanexx used a Malawi 2 Regatta pop up tent. The most important factor is it being a single layer tent, and probably having waterproof rating 3000 hydrostatic head. Zanexx used canvas tape and plastic bags to cover the air vents inside the tent. I've bought Gorilla tape, as it said on the packaging that it can be used on tents. I tested it, and it does stick, but not extremely well, and i'm a bit worried if it's too damp or cold, it might not hold well enough. But, i'm planning to choose a day with good weather - low wind, dry, not freezing cold.

-Zanexx succeeded by entering the tent with the charcoal. But, importantly they had benzos to help sedate and overcome anxiety and panic. I haven't been able to get benzos, therefore, letting the CO build up first, and passing out much quicker, is probably the better option for me now.

Thanks for the info really detailed. And good luck fella
Just really surface questions but how long should the buildup be? And is it true that i should bring the charcoals inside as soon as possible (when there's no smoke obviously)

I bought two 2.3kg capacity chimney starters. I plan to put 2kg in each one. I think the instructions say to burn for 20-30 mins to get the briquettes started. I'm thinking of maybe buying another chimney starter, and 4kg more briquettes, then i can have almost 7kg charcoal. Someone here failed in a car with about 1.5kg i think, but another poster said they succeeded in their next attempt with 7.5kg charcoal. But, i think Zanexx had one chimney starter, and succeeded with maybe 2.5kg charcoal.

I think Zanexx said the smoke had gone, but there was still some flames when tipping the charcoal out of the chimney starter, into the bucket. They then waited 90 mins for the briquettes to cool down before taking them inside the tent. See this post, and the linked article - https://sanctioned-suicide.net/threads/leaving-tonight.3163/post-44368 - The poster Zanexx replied to suggests it's important not to rush taking the charcoal inside, and the linked article is about a lady who accidentally died, when a cool bbq was taken inside a tent 5 hours after being started. The man spent 2 weeks in intensive care, but survived.

So the longer you wait for the charcoal to cool the better CO emmision? Good info and thanks, i'll study zanexx's post a bit more.

For 2kg+ briquettes from a chimney starter, waiting 90 minutes or so, like Zanexx did, seems a good guide. It allows the heat to go down and therefore, reduce the risk of the tent burning. Even after 5 hours, enough CO was still being emitted for the lady to die in the linked article. But waiting 5 hours would be risking the CO levels declining imo, and surviving like the man did. Waiting about 90 minutes after tipping out of the chimney starter into the steel buckets, is my plan.

There are a couple of cases here where people failed in cars. I think both times, they used possibly not enough charcoal, and also took it into the car quickly, whilst it was still very hot. The one case, he sustained organ damage. It is the big drawback with CO over SN. If it doesn't work, you can survive with serious organ damage.

A lot of people recommend buying a CO analyser capable of measuring up to 10,000 ppm. The plan is to get the CO up to 10,000ppm first, and enter the tent, and then pass out very quickly.

I feel like a 10 000 ppm meter is not really a necessity i mean think about it southeast asians die like this all the time and they dont bother measuring ppm levels. Even around 1000ppm is deadly enough to kill you in a few hours but of course 10k is the best.

Certainly you can use disposable charcoal grills. You'll def need more than one. I think tent is best. Don't understand idea about bathtub. How are you planning on being in tub along with several disposable grills? You let CO build-up and then enter. To avoid headaches, nausea, etc the level of CO needs to be really high, like 10000 ppm or more. That way you go unconscious almost right away after entering the space and starting to breathe the CO. Only way to know for certain whether you created an environment with a high CO level is to buy and use a CO analyzer to measure it. Don't do any CO in a house where others live and could get exposed to it, even if they're gone. They're going to come home eventually and it might harm them, even kill them.

Yeah got it tent it is then.

Whoa lets go site is back up. So i have the same tent as zanexx on the way which is cool. I have read that the disposable grills carry around 0.4 kg which SHOULD mean that 6 of them could be enough. Question i've been wondering is, how long should the buildup be ideally? And in total how much time do i need from start to finish with this method? Ive been thinking that 11 hours should be ok (need to plan having the house to myself)

I don't understand why CO isn't more popular. You would think it would be but it's not.

11 hours sounds like plenty of time to me. You have to set up the tent, tape up the air vents first. I'd guess that 0.4kg disposable bbq's burn quicker, and cool down more quickly. 2.5kg briquettes need about 30 mins in chimney starter, and 90 mins to cool down.

I'll be honest, i worry about you using disposable bbq's. I read that they don't always contain the best quality charcoal, and can contain additives, fillers, binders, and pre-applied lighting fluids. If you used 6, you'd be at 2.4kg, and Zanexx was successful with a similar amount. But Zanexx used Weber briquettes in a chimney starter.

I'm very anxious by nature, so i have 4kg briquettes, and i'm thinking of getting more and using 7.5kg. Someone in the megathread described surviving an attempt in their car, and the damage it did to their body. Sorry if i'm being annoying, but i really think you need to be very careful with this method.
Hi, if you've made up your mind about doing this, be very careful with this method. I just got out of the hospital after attempting with the CO method in my car and may have lasting internal organ damage.

I used high quality lump charcoal with a $450 CO meter from TPI, followed @befree's (RIP) method to the T, effectively creating an airtight seal in my car with gorilla tape, using 2 charcoal grills with sufficient coal based on the interior of the car, etc. I reached 7000+ ppm (yes I know it's not 10,000+ but this should still kill within hours at the most and I was in there for 6+ hours undisturbed) which it maintained until I passed out and presumably after. Getting in the car, it was extremely hot (but not smoky, since it was only CO being produced), and I'm still having flashbacks about the few minutes I was hyperventilating in there and dousing myself with cold water to stave off the heat.

6 hours later, I woke up effectively paralyzed (I must have had convulsions in the car and paralyzed a lot of my muscles) and with intense brain fog and wasn't even able to reach the keys in my ignition, only my phone which was laying a few inches from my fingers to call my mom with a voice command.

In the hospital all my vitals were fucked and they pumped me full of oxygen with a high flow mask for a few days with a rotating CNA watching me 24/7 (yes, even as I shit). My ejection fraction was 20% at one point with severe chest pain and troponin in the thousands (like a heart attack). I may have lasting scarring on my heart that will increase my risk for heart attacks and may have to go on dialysis for my kidneys because I fucked them up so much with this (I'm in my mid 20s). Of course I was then transferred to the psych ward which is a whole nother can of worms but let's just say nothing has effectively changed since the 50s. Overall, this was an extremely traumatic experience. I'm not one who ever befor experienced PTSD flashbacks daily but now I picture getting into that car and hyperventilating with the heat daily. This experience has supremely fucked me up both mentally and physically. I may also have brain damage which can manifest in memory loss and cognition delays weeks or months down the line (stay tuned!)

Just sharing my honest experience for your guy's perusal and consideration. Thanks for reading if you made it this far.
Thanks all who replied with your support and kind words :) Me and the doctors both don't really know what "saved" me, the only things I can think of are a possible genetic resistance and maybe the concentration dropping extremely low when I opened the door for a second to get in the car and the display being slow to catch up or something?. Or maybe the meter (TPI 707) wasn't accurate for some reason, although I did follow their guide and calibrated and purged it in clean air beforehand and everything. Unfortunately I wasn't able to see the display reading on the meter when I woke up about 6 hours after getting in since I'd knocked it away when I probably thrashed in my sleep.

No preexisting health conditions, and only other thing I can think of is it had rained a few days beforehand so the damp/cold weather may have been affecting the charcoal's burning time? I did take about 3 hits from a THC vape pen, a handful of 30mg weed gummies (perhaps a bit much :o ), and a bottle of pinot grigio about an hour beforehand to calm my nerves and help me ease into sleep, so maybe I went a little too crazy on that? One other poster asked about how long I was in the car before it reached 7000 ppm; sorry for not clarifying before but 7000 ppm was what I read immediately before I got in the car and opened the door; the numbers continued to hover around that afterwards though, sometimes dipping to the high 6000s but maintaining around that level at least while I was conscious to read them. I can recall being in the car for probably about ~2 minutes during this time and reading those numbers while dousing myself with water before I lost consciousness. The only physiological reactions I got during thos emoments were the hyperventilating and the feeling of the intense heat. But yeah like I said I guess the level could've dramatically fallen right after that somehow though? Really have no idea.

And yeah, based on the reaction I'm sure there was some lingering CO2 present but it wouldn't seem like there was a great amount by that time just based on observation. I waited a good 45mins-ish to an hour after lighting the coals and made sure they were only smouldering/no smoke was being visibly produced, and I would've expected to have a lot more effects like coughing or eye irritation when I got in the car if there was somehow a sizeable amount of CO2 still being released by the coals, right? I would be interested to see that concentration too though.

Ayways, I'm now in a 5 day a week Adult PHP program which is definitely...something lol, at least it's not the psych ward. I was kind of in a rut in terms of my schooling/career before this and am kind of taking this as a sign to drastically change my life path towards something else and just shoot and see what happens, I may as well I guess. Not religious or faithful at all, but all my CNAs during my hospital stay kept saying that I must have failed for a reason and I still have something left to do, so I guess we'll see about that haha. So not currently planning to imminently CTB, but the fleeting thoughts are definitely always there. Thanks for asking :)

I don't mean to alarm or scare anyone necessarily with my story, but I just wanted to put it out there as a data point for consideration, this very well may have just been a fluke or anomaly, it seemes to have worked as expected for very many others who went through similar steps with the method and may have reached similar concentrations, etc. As a part of my treatment plan, I think I'm going to deactivate my account for the time being at least; I hope the details I provided can somehow be of use. Thanks for taking the time to read my experience regardless :)
I thought i should just link these posts that i mentioned, from the megathread. Sorry if i'm being annoying, but i think it's good to have as much info about other members attempts with this method.
