Back in high school, I used to get blocks of the stuff given to me all the time. This also was not pipe scrapings, but commercial stuff (origin unknown).
In my opinion, resin is strong and nasty stuff. Not long after I started getting into resin, it killed all the pleasure in my THC highs. Thereafter I started getting paranoia after even a tiny amount, not just on resin but weed as well. I started smoking a small amount of weed again recently (after about 10 years) and finally been able to get a mellow buzz again.
But I still have to watch it, it's still a fine line until Mr Paranoia comes knockin
