look online for "freebase" style smoking devices, guides on how to make one. DMT is most efficiently smoked out of meth or crack type pieces. take as many hits as you possibly can in one go and hold them in for as long as you can. i dont think i really "broke through" until my third time or so. its best done with a specialized hitter out of a bong IMO. keep in mind tolerance sets in pretty fast, so trying hit after hit to get higher is not a very efficient way to make use of your stash.
