Really haven't read the past 10 comments, but I want to contribute.
Nasal spraying works wonders for a chemical I tried a year and half ago
I used either 100-150mg of 25c-nbome, and mixed it in with water using an Afrin push-to-spray plastic bottle, which let me remove the spray mechanism with my nail. Don't remember how much water I used, or that I even cared. But one spray got me 2-4 blotter hits easy. All my friends, girls too, loved the idea of having a psychedelic spray. Nobody was quite sure what it even was, and I had practically nothing to say about it, but it did it's magic, and never ran out after countless summer parties, and beach trips. There was still a good fraction of it before I lost it, so it just goes to show you how well you can ration nasally active chems through this procedure.
I wouldn't advise dumping the powder/liquid K into pure nasal spray solution, as I have no idea what reaction on the chemical it would have, so please use clean water when attempting this method.
One major complaint I had with 25c-NBOME, is my nasal passages, and some parts of the lungs felt tremendous pain in form of a burning sensation for at least a couple hours after inhaling. pain was peaking at around 10 minutes, that lasted for an hour of discomfort, tapering off in the hours to come. but It was a big letdown, as the peak of the drug coincided with the pain of my nasal passages.
I would warn anyone willing to go this route, but I don't know if there is reported pain on this chem, you'd have to find for yourself.
Remember 25c-NBOME is a phenethylamine, and a derivative of 2c-e, which has been noted to sting like a mother fucker when snorted. So Ketamine could be different.
Worth a try though. Don't listen to people claiming it wont work, because they're speaking out of their ass. If the chem is snortable then you bet your ass it;s gonna work wonders when used as a spray, there's literally No reason for it not to work unless it does pass your esophagus into your stomach.
Which is why you ABSOLUTELY
Have to make sure to get a Full Mist Spray bottle, as if you just pour the liquid down your nostril with a pipette or the like, its just going to slide down your throat.
Full Mist Spray will linger in your nasal passages until it gets fully absorbed into your skin. Can't wait to try this myself.
