ok thank you guys for the answers! I have tried snorting freebase before and it burnt pretty bad (a very small amount that only gave me slight buzz for 2 mins).
However, I just recently snorted ~250mg fumarate (at 75% it was equal to 190mg freebase) and was amazed by multiple things. First, the fumarate does not burn almost at all. It sure was uncomfortable but it wasn't painful. Second, it was totally awesome first time experience but I know I didn't break through.
At the peak I was constantly feeling some emotion of utter pleasure and felt like blending with the room as if I was part of it. Also, looking into mirror was really cool, call me vain but I haven't seen myself being so beautiful before. So, unfortunately I need an even higher dose to get the spiritual experience I'm looking for. I have failed miserably at building the machine multiple times and ended up wasting 250mg freebase, that's the reason I decided to snort instead of attempting to vape.
