I haven't tried MK-801 I just like to read about it, not sure I'd take it, although, nah if I found it I would take it haha. Seems to be in that tiletamine type class of drugs which give you the sort of state i like to the "the dumb" where you feel detached, synthetic, industrial and either strongly neutral or dysphoric and scatterbrained. Although its probably still novel even if it sucks!
What I was thinking with the drugs that I mentioned are things like how ibogaine was traditionally used for thousands of years in religious rights until a random junkie took it out of boredom and curiosity and discovered it's profound anti-addictive effects. Also considering it's very odd chemistry and its action on so many receptors, like 5HT3 and NMDA just seems like a very odd drug to exist.
Or PCP, I forget where I read this but I remember seeing that it was first synthed in the 1920's by a german company as a pesticide, before park davis picked it up. Then it was trialed as a human anesthetic because it could anesthitize without slowing heart rate or breathing at very small doses. Imagine being a volunteer in that trial in like 1958 or something! Then rejected because of "nightmares and psychotic reactions", sent to the veterinary clinics and then to the ghetto. Seems like an odd drug to be a gangster type of drug.
And then DiPT! How does it have such a specific effect!? What is it about the diisopropyl that has so much to do with sound and pitch?? It sounds so strange! Percussive sounds are unaffected, but all tonal sounds gain extra tinny alien octaves to them, the beatles sound like tiny robot aliens! This must have some application in investigating the mechanism of human hearing.
