Oh also, when you vape it, it's going to feel poisonous at first. It's got a bit of the DMT intimidation "oh what have I done" to it when you smoke it, as well. But yeah, when it first starts to come on the side effects can feel pretty nasty, which can make it hard to buckle down and keep smoking it. Vasoconstriction, flushing, prickling skin sensations, cramping, headache, nausea, and vomiting are all possible. Varies from person to person. Fortunately, they're not severe for me.
The side effects pass quickly, though. Usually 1-1.5min, then the comeup starts. I get the most stunning OEV visual display of any drug and CEVs equal DMT. But there's no content, no meaning, and no depth. It's just pleasant, empty confection.
I hear that when it's insufflated it can be a more meaningful experience, but I'm not interested. I bet that would burrrrrn.
