I applied to be in a similar trial last year. The doses of Ketamine were higher than the doses listed in the trial you linked and were given via IV at the hospital along with another drug that blocked the hallucinogenic activity so you'd get the benefit of the K without any of its dissociative effects. The tech I talked to was surprised that I wanted to keep talking after I found that out. He said that they get a poo poo ton of inquiries about it and the vast majority lose interest once they find out that they aren't going to be given a bag of drugs and turned loose in the street.

KozmoNaut posted:I love everyday radioactivity, so I have one of these tritium marker lights on my keychain: I have several hanging from the bookshelves along the wall next to my bed. I used to have a habit of running into the corners at night when I was bleary. Now the corners each have a tritium light, so I don't ram my skull into them at 2AM. Technically, this is illegal, as tritium is not supposed to be used for "trivial purposes" in the United States. Gun sights are one of the few approved uses. However, I consider avoiding brain damage due to being barely awake to be nontrivial.

Legend has it that Finnish military doctors did emergency G-E surgery with the patient spontaneously breathing under ketamine anesthesia. It's also becoming more common in emergency medicine as an analgesic, and particularly as a sedative for endotracheal intubation. First comes 1-2mg/kg ketamine, then an appropriate dose of a neuromuscular blocking agent ("paralytic") and voila, easiest intubations ever. Plus, at that dose of special K, the patient gets to benefit from the powerful dissociative effects as well as the amnestic effects. You won't even remember what happened that led to you being intubated. It's like a miracle drug! Except when it provokes psychotic episodes, but hey, can't win 'em all.

KillHour posted:Piranha solution is sulfuric acid and H2O2, not nitric acid. I've used it for REALLY stubborn drain clogs where the sulfuric alone couldn't handle it. Doesn't this kill sewage bacteria? Probably not a good idea because you want them alive to break down your poo poo.

Phobophilia posted:Doesn't this kill sewage bacteria? Probably not a good idea because you want them alive to break down your poo poo. Only in concentrated form. By the time it gets into the sewage treatment plant, it will be diluted to homeopathic levels. Additonally, HOOH slowly breaks down into water and O2 by itself. I wouldn't worry about this. There's worse things you can pour down the drain.

darthbob88 posted:How's it handle plastic pipes? I've got a stubborn clog that might require something stronger than lye, but if it melts the pipes that's obviously no good. A quick google tells me that while hydrogen peroxide itself doesn't harm plastic, piranha solution can. Be careful with that stuff. Other than lye, there's also simply acid-based drain cleaner, often sulfuric acid. You could try that. Or you could try the home remedy listed on quite a few websites: pour down baking soda followed by vinegar. The idea is that this causes a vigorous reaction creating a lot of CO2 which works the clog loose. I don't know how well that works in practice, though. Personally I had the most luck with mechanical ways of cleaning it. The good ol' plunger and if that doesn't work, a drain snake.

This stuff is what I typically use for shower drains that get hair and gunk stuck in them: http://www.homedepot.com/p/Instant-Power-67-6-oz-Hair-and-Grease-Drain-Opener-1970/100169339 To be clear, the reason I used piranha was because the clog I was trying to get out was some sort of crazy mold that had built up in my basement's slop sink drain after someone who shall not be named dumped a crock pot of old chili down it. It was me. I'm the idiot. I started by pouring about 2 cups of concentrated sulfuric acid down there (that I bought from Duda Energy via Amazon. Unfortunately, Amazon no longer carries the stuff so you have to go straight to the manufacturer's website). When that was obviously not doing anything to the furry bastard, I chased it by (SLOWLY) pouring 34% hydrogen peroxide (the only place I found to get that stuff is from those stupid homeopathic companies that want you to put a drop of it in a glass of water and drink it. loving stupid, but it beats the poo poo out of trying to make your own on the stove) on top. That pretty much immediately turned the whole thing into the world's grossest milkshake, which I could wash down just fine with cold water. This should go without saying, but

That stuff from homedepot is just a NaOH (~50%)/KOH (~3%) solution. It's probably cheaper to buy the pellets and just make your own solution, FYI.

Some meatheads in my high school chem class liked to drop pencils and pens down the drain of the lab sinks, which naturally then clogged up. So he just waltzed back to the chem closet and grabbed a jar of straight lye (NaOH) pellets and dumped a generous handful (not with his actual hands  ) down the (backed up) drain, completely dissolved the writing utensils. Sink ran real fast after that.

Caustic soda is good for fatty blockages, acid is good for proteinaceous ones (hair etc).

If its the stuff you buy at the store, he's drinking diluted 3-6% H202 and then adding more water to it, making it even more diluted. It's probably not a smart thing to be doing, but it probably won't hurt him.

I knew someone who had tritium night sights on a gun for coon hunting. He used to leave it under a lamp for a few hours so it would charge with light sorta like those glow in the dark stars you stick to your bedroom ceiling.

If it needs charging it's not tritium - that just glows all the time (when mixed with the right phosphor).
