you can smoke it on foil (much like roxies) but it isn't that effective, and it doesn't work as well as say, heroin when you chase the dragon. I have done it a handful of times and the high has been barely discernible. there are better routes of administration, but either way:
ideal how to:
-get a piece of *untreated* aluminum foil with the dull side up (shiny side down). kitchen foil has lots of chemicals which you will burn and inhale. not good.
-fold the foil hot dog style, making a 'v'
-crush your pill and sprinkle into intersection of foil
-get a straw/pyrex stem/cardboard toilet paper roll you will use to direct the vapour into your lungs. using an additional piece of foil cna be good, as you can smoke the resin later.
-get fire. i usually like to use a tealight because i'm not an octopus and only have so many hands
hold the straw in your mouth, the foil in one hand, and heat the pill on the foil slowly and evenly. if it crackles/browns you are going too fast and will just burn your drugs. when you see vapor, inhale. repeat until finished.
foil gets hot, be cautious, and it smells sickly sweet. good luck
