Vaporize it or your not going to notice to much of a differance, use hot knives of you don't got a vap. Pressed keif isn't hash by the way. You have to cook it for it to become hash, or so i belive. And trust me there is a great differance between pressed and hash. Never smoke it in a J either, it just seems so waistful. There is a video on-line on how to cook hash if you want to learn, I don't think it should be pressed though.

Good luck, Good high. . .
