Salvia D, or Sally D
also, kif/keef can be a couple things. A Kif Box is little weed grinder basically and it just breaks the pot up to roll its easier. some people call the ground up stuff the kif.
After the box has been used a lot theres a very nice residue left from all the crumblys in it that can be scraped out and is pretty much pure THC/other canabinoids
Edit. Salvia is the most wacked out shit, if you get the chance to try it sometime do it. It only lasts 5 minutes (literally). If you dont like it the first time id recommend taking a second go at it as people generally have a hard time "breaking Through" in that S.D. seems to have reverse tolerance in the more you smoke it, the less it takes to reach the plataeu of "enlightenment".
oh and NOT A PARTY DRUG youll regret every second if its in a loud brightly lit place
