Can you provide any study reporting unconsciousness in under 15 seconds? The best results I've seen are 16 - 17 seconds or 17 - 20 seconds for unconsciousness and 12 - 14 seconds for the onset of symptoms from over-ventilation with nitrogen

Most of the time, you'll see unconsciousness listed around 16โ€“20 seconds, depending on factors like breathing rate, prior saturation, and variability. That said, there are a couple of studies that support symptom onset just under 15 seconds, especially with over-ventilation beforehand.

A few sources from my bookmarks:
  • The Copeland Report on Nitrogen Hypoxia (written for legal and clinical review) notes visual dimming at 8โ€“10 seconds, clouding of consciousness by 15โ€“16 seconds, and unconsciousness between 17โ€“20 seconds:
    https://dpic-cdn.org/production/legacy/Copeland Report_Nitrogen-Hypoxia.pdf
  • The U.S. Chemical Safety Board training materials also reference oxygen-deficient environments causing rapid collapse after 1โ€“2 breaths, especially in enclosed spaces with pure nitrogen:
    https://www.csb.gov/assets/1/20/nitrogen_asphyxiation_bulletin_training_presentation.pdf
  • "A Study of the Human Tolerance to Oxygen Deficiency in Relation to the Inhalation of Inert Gases" by E. M. Camporesi and D. B. Barker: This study explores human tolerance to oxygen deficiency when inhaling inert gases, noting that loss of consciousness can occur within 15 to 20 seconds under certain conditions.
  • "Sudden Loss of Consciousness Due to Oxygen Deficiency" by R. H. Clarke: This paper discusses cases of sudden unconsciousness resulting from oxygen-deficient environments.
  • "Inert Gas Asphyxiation: Time to Unconsciousness and Death" by J. D. Ernsting: This research examines the timeframes associated with loss of consciousness and death due to inert gas inhalation, indicating that unconsciousness typically occurs within 15 to 20 seconds.
But yah, you're probably more right than I was initially! Most of the documented cases put true unconsciousness more around 16โ€“20 seconds, especially in controlled conditions. I overshot a bit.

That said, there's enough variability in ventilation rates, individual oxygen reserves, and pre conditioning (like hyperventilation) that symptom onset can still show up a little earlier for some. So while sub 15 seconds for full LOC isn't typical, I still think it's possible, just not something to bet precision on.

Appreciate the correction though! Accuracy matters. ๐Ÿ’ƒ

How about jumping from at least 7 stories up, with landing on back of head?

Probably be fentanyl/opiod overdose or N.

Then gas and SN

Excluding scenarios like Titan submersible, or being into Ground Zero of a Nuke, the Top3, The Holy Grail is as following (Yes, most methods are painful, but believe me, those ARE painless!!)
  • Nembutal, or barbiturates in general,
  • Inert gas / Exit bag
  • Opioid overdose (ideally with other CNS depressants like Benzodiazepines, GABAergics etc)
Closely followed is (I guess, because it may hurt but for a split second) massive but super short trauma to the head, like: intraoral shotgun blast, guillottine, or landing from 50+ onto concrete head first.

I know some people might disagree with me but death is pain. No matter what you choose. You will feel pain.
dying "peacefully" in your sleep is not true.

I think from what was written before are those barbiturates, then gas and SN, problem with tho later is you can end as vegetable so you must have backup plans

Solid clarification. The brain does keep running background systems even in altered states, and you're right: pain signals can still activate motor responses or trigger fight/flight reflexes before full unconsciousness. That's why some methods that seem peaceful can backfire if they're too slow or allow for prolonged discomfortโ€”because you might not consciously register it, but your body does, and that can be enough to jolt you back.

Short duration pain? Probably won't matter. But anything extended? That's where the risk of waking, panic, or reflexive survival kicks in.

Appreciate you adding thisโ€”more people need to understand that "not feeling it" isn't always the same as "not reacting to it."

That whole "one touch and you're dead" thing? It's mostly media fearmongering. You're not going to die from touching fentanyl unless you're exposed to a large amount in aerosol or powder form and inhale it directly. Skin contact alone, especially brief, isn't enough to cause an overdose. Even emergency responders have walked that back after the initial panic headlines.

As for using fentanyl as a method: it can be lethal, but it's not reliable unless you know exactly what you're doing. There's a high risk of survival with brain damage if dosing isn't precise. Plus, it's often mixed with other substances unless it's pharmaceutical-grade, which makes it even harder to calculate.

It's not the clean, instant fade people imagine. Respiratory depression takes time, and many people vomit, seize, or panic before losing consciousness. Some survive with permanent damage. Some die horribly.

So yeahโ€”possible, but not as peaceful or foolproof as it's often made out to be.
Can you give advice per fentanyl protocol?

I think that a cave where one is surrounded with tnt, can cause a painless death as the whole user is rapidly destroyed, and if the cave room collapses, there is no easy retrieval of the user

Russia supposedly "lost" a handful of suitcase nukes around the time the Soviet Union collapsed, and there's a handful of deserted islands that were used for nuclear testing in the South Pacific. Just sayin'

Taking the title literally without any context nuke. Got to imagine the peeson walking in Japan who got "vaporized" probably wins the award for ever. Just walking along living your best life. Brain doesn't register anything. No fear nothing. You dont even know how you died. You dont even know that weapon even exists. I can't even imagine the WTF moment they'd have with God.
