About three or so years ago I got a few batches which were very easy on the nose and didn't taste awful when vaped (especially as only a tiny quantity was required). I also had batches that were as you described, and with those I stuck to oral use.
Unfortunately there's rarely any way to know if a batch will be suitable for vaping or nasal use beforehand. Just the way it is with RCs - or street drugs for that matter.
Did you use it orally? How did you find it?
