Alabama is seeking to become the first state to execute a prisoner by making him breathe pure nitrogen.

The Alabama attorney general’s office on Friday asked the state Supreme Court to set an execution date for death row inmate Kenneth Eugene Smith, 58. The court filing indicated Alabama plans to put him to death by nitrogen hypoxia, an execution method that is authorized in three states but has never been used.

Nitrogen hypoxia is caused by forcing the inmate to breathe only nitrogen, depriving them of oxygen and causing them to die. Nitrogen makes up 78% of the air inhaled by humans and is harmless when inhaled with oxygen. While proponents of the new method have theorized it would be painless, opponents have likened it to human experimentation.

          Years ago when I was in a bad place in life I attempted suicide using a tank of nitrogen and an oven bag. Thankfully I was stupid as hell and didn’t tie the bag properly or something. So when I passed out the bag managed to come off somehow. Still not entirely sure how it happened but either way I’m thankful it did and I managed to survive for better days.

          Anyways, Im telling you this to let you know I can very much confirm that breathing nitrogen is painless and was no different than regular breathing.

          Your body only starts the alarm bells when it can’t exchange out the co2 in your lungs. It can’t really tell the difference between pure nitrogen and some other gases coming in vs the optimal mixture we need to breath. So the alarms never really go off. There’s more to the science behind it, but it’s kind of a glaring flaw evolution left in our bodys survival system that can be taken advantage of including for use in anesthetic.

              Yeah sort of. At first I started feeling very drunk, but not like normal drunk. I can’t really think of good analogy other than it was like half way in between drunk and a small amount of anesthetic maybe?

              It was this slow dip into unconscious, it wasn’t like sleeping where I’m vaguely aware of the passage of time. But it wasn’t the instant knock out of anesthetic or normal unconscious either. It was like lowering myself into a pool if that make sense. Wasn’t a bad feeling, just kind of different. Had an awful migraine that lasted a couple of days afterwards though.

              Thanks I’m extremely happy everday with my failure! Lol

            Helium (as a suicide method) has been around a while. My best friend used it to kill himself 13 years ago. Maybe it’s making a comeback.

          I’ve been in a high altitude simulation chamber to experience hypoxia after rapid decompression. 💯 didn’t give a fuck, was a bit giddy, and if left there long enough with dwindling oxygen would have for sure died. No problem taking a breath.

          So in effect, yes tried it.

              haha I can’t remember if we were doing cards like that or not. I remember having to answer questions writing them down on a form. Between the handwriting and the answers themselves it was hilarious; and of course educational. It was for certification to do high altitude jumps. you can bet your ass I made sure I was on oxygen per regs every time. No forgetting to pull the cord for me thank you very much.

            I was beginning to wonder if breathing pure nitrogen was some kind of party trick or rite of passage for science geeks.

          I have, sort of. I’ve worked HazMat most of my life. One of the jobs I had years ago involved neutralizing a large pit of acid. It was just a huge pit in the ground with a roof over it. From the outside, it just looked like someone had pulled the roof off of a house and set on the ground. There were only two openings, one at either end, so it was completely enclosed. The method here was to send the two youngest (and therefore invincible) guys into the pit with acid suits and full faced respirators, with buckets of soda ash, we walk around in it and stirred it up while we sprinkled the ash around. Safety standards back then were not what they are today. Anyway, the people in charge realized that there would be a reaction with gases betting released, hence the respirators, but no one considered the possibility that the gases might be heavier than oxygen. Which they were. We didn’t know what kind of acid it was but this was an old fertilizer plant, so probably nitric. Which means the gas was most likely nitrogen. Whatever the case, we got into trouble when we realized that we were both getting rather lightheaded. We tried to leave, but the only way out was up a ladder and by the time we got to it the other guy, we’ll call him Rick, could only get about half way up before he just couldn’t move anymore, which left me leaning on the ladder at the bottom, completely unable to help, as I was in the same state. Luckily, our foreman was a lunatic and he jumped in and pulled us out. You are absolutely not supposed to do that because you are just as likely to end up in the same trouble as the guys you’re trying to save.

          The experience with the gas was not unpleasant. I should have been terrified, but was mostly just mildly concerned. The only real effects I remember feeling are the lightheadedness and being really sleepy.

      Nitrogen hypoxia is a risk wherever liquid nitrogen is used. If too much boils too fast, it will displace the oxygen in the room. People in the room won’t even realize what happened until they pass out and die shortly thereafter.

      There are reports of people rushing in to rescue those who passed out, and suddenly passing out themselves and needing to be rescued as well. That’s how insidious it is. And that’s why MRI scanners (which use liquid nitrogen) have oxygen sensors in the room. You can’t trust your own body to tell you that all the oxygen is gone.

        MRI machines are cooled by liquid helium. Nitrogen is not cold enough. I’d imagine as a noble gas it has a similar effect though.

          They are cooled by liquid helium, but also have a liquid nitrogen outer dewar as well with a vacuum insulator in between. The N2 takes the brunt of the ambient heat so you don’t have to top off the (much more expensive) helium as often.

      Can you please share more of your experience? What was the occasion and the set-up? What was it like?

      I’m willing to bet what you inhaled was carbon dioxide – that gives an instant feeling of suffocation. Which ironically makes it one of the safer asphyxiant gasses, as it’s heavier than air and you can detect it’s presence instantly. Inert (“noble”) gasses like helium, argon, and nitrogen don’t have that effect.

      CO2 is also cheap, readily available, non-toxic, and doesn’t cause physical damage. This makes CO2 asphyxiation somewhat popular for “stunning” or killing in places like slaughterhouses, labs working with smaller animals, or “feeder” animals for reptiles.
