Your friends were so stupid on ketamine that they needed a babysitter.

Let me just point out a few things. You could have said "in that case, all drugs make you stupid" which would have been totally valid. You could have said "at the dosage necessary to incapacitate someone, of course they would be stupid", which of course is valid.

The whole point of my very first comment was to poke at people who love ketamine, and also those who read studies about ketamine and proceed to spread it like gospel.

There isn't a recreational drug that exists that makes anyone temporarily smarter. They all make us temporarily more stupid. For some reason drug users get real uppity when you point that out, especially about their drug of choice. That's not to say that something can't be taken from the experience that helps someone, or that might inherently make them smarter or self aware. I was just simply stating that when on that drug, you are more stupid. I think that's a lesson that a lot of drug users should be more aware of.

I've seen a lot of dumb shit happen because someone was mislead about a drugs effects. Hell, I have some K in a stash right now, but let's not misguide people into thinking they will just be coherent floating brains. They may also be floppy dumb messes that may need babysitting for 45 minutes. Will they be just as smart afterward? Probably. But for those 45 minutes they are going to be stupid.

Good on you for being a trip sitter. You're good people. People deserve to try drugs in a safe manner and that's what leads to good experiences. Those good experiences are what those stupid people deserve.
