Just completed my deep (40m/120ft) diver certification. A significant amount of the course was focused on nitrogen narcosis, and how to handle/detect it. Apparently, some divers will start feeling the narcotic effect between 20-30m. Beyond 30m, a significant amount of divers can feel the effects. Beyond 40m is the realm of tech diving, with trimix (helium/nitrogen/oxygen) or even heliox (helium/oxygen). I know nothin…

"Except for helium, no other gas exists which does not have some form narcotic effect at higher pressures." I assume the narcotic effect of fluorine, chlorine and bromine are basically unstudied...

You may have confused narcotic with necrotic.

Yeah, physician (pathologist, specifcally) with a degree in physics here. I'm going through articles in other tabs right now just because I'm skeptical enough to consider crazy ideas (always good to build bulwarks), this is, at best hypothetical, but mainly the chain of causality in the above statements is a hot mess. I spend a lot of time looking at cell membranes. More than almost all of humanity. The naive Fluid M…

Yes, this is a contested theory, but it's not a crackpot theory. I'm well aware of the fluid mosaic model. It is not mutually exclusive with what I've described, in fact it's the base from which this theory is formed. And it is not my theory, but the theory first formulated by literally the guy that discovered the mechanism of action of myelinated action potentials (Ichiji Tasaki, who worked on it during his entire t…

A 10% increase in reaction time could be fairly significant in many sports. Could we start seeing football players, sprinters, or baseball players breathing from masks between plays?

You already see this. Google "NFL oxygen masks". I'm sort of surprised I haven't heard about it in the context of shorter physical sports: I'd wonder what effect it would have on an 100m/200m/400m time or shotput distance to oxygen saturate like free divers do.

It is not uncommon for drivers to take supplemental oxygen for the pike's peak hill climb event.

"We’re basically continuously narked, we’re just so used to it we don’t even know." Just because one direction on the gradient means that we respond in a way that looks like a narcotic does not mean that the other direction will respond in the opposite manner. I'm sure the nootropics folks would have discovered being super not high by now if it were as easy as breathing a mixture that doesn't have nitrogen in it.

as siblings commented, pure oxygen gets you high. a couple of breaths of pure oxygen will relieve pain and induce euphoria. I am not entirely clear on the definition of "narcotic" so i may be being redundant. My issue, though, is i can't find a way to safely generate oxygen for a decent price. I know electrolysis works, but these atomic sieves look safer. They're also difficult to acquire without a prescription, at l…

> a couple of breaths of pure oxygen will relieve pain and induce euphoria.

Nah.

I've breathed pure oxygen under water for 10 minutes at a time at a ppO2 of 1.6 and it doesn't really do much.

Yikes, I just checked, and Captain Morgan's is 35% Alcohol. I'm aware of Bacardi 151 (75.5% alcohol) which is like fire water to me. Can't imagine drinking something so concentrated regularly.

I suppose that's why 1 part of rum got mixed with 4 parts water and some limes.

The lime got added to prevent scurvy, which was a major problem prior to it's addition

I have experienced nitrogen narcosis before. It was like getting drunk very fast, including the room spinning. I hugged myself and ascended maybe 2-4m above the rest of the group and got back to normal pretty quickly after that and was able to continue to the dive.

What is the significance of hugging yourself in that situation?

You'd hope mind-hackers would've explored & confirmed/refuted/quantified the effect, but stuff like this often lies underexplored for decades, despite hints like this 1975 study – which actually shows the 'gradient' of clearer thinking continues in the other direction, no hand-wavy extrapolation required. It's what they found! In 1975! How long did it take for society to fully recognize, & remediate, the effects of e…

Maybe it remains underexplored because if you find a significant effect and popularize it, then the substance gets banned. The people interested in using stuff like this have an incentive to avoid scientific research on the subject.

Hell, even NAC almost got banned recently.

9% decrease in response time would be pretty significant for gamers. Look out for LED illuminated gamer branded helium tanks.... and if you think online gamer chat is annoying now, wait until you get called a noob in a super high pitched voice.

Neon is allegedly non-narcotic too. Being closer to air density, it can be part of a non-funny-voice version of gamergas.
