Anon who works with it on a daily basis, it won't knock a person out, it stinks to high hell (like paint thinner) and you need to breath it very heavily for a solid 2-3 minutes. I assume you just want to huff it to knock yourself out for fun. So instead I recommend you get "butyric acid" on eBay (10-100g should do) and then boil 1L water. *While* the water is in a rolling boil dump it in so it dissolves, then just let it cool and you have your kock out water. Just use a stove, and some ceramic or stainless steel pots, and you may want to keep your face away from the bag/keep it closed, do not smell it and possibly wear a mask until the water cools, you don't want to risk getting hit while working with boiling water. Lastly, if you notice a bad smell, that's just a decomposition product and goes away with more boiling. Butyric acid is kinda like GABA in the human body and will sedate instantly and get you very buzzed. Remember, butyric acid. You can also try pyridine. But no other butyrates are as potent on inhalation.
