I've found that the 'chasing' method certainly is the most effective without much practice; tear off a small piece, start with perhaps .05g on the edge of a piece of foil, and hold it almost vertically, with a rolled up piece of foil as a 'pipe', heat, and follw as it bubbles' down the foil.
Another good method it hot knifing, but rather than (with cannabis) violently pressing the knives together, just touch them ever so slightly, over, and over; as to catch all of the vapour - don't waste any of that sweet sweet O
If it really is O of course!
