this method def does work, i only recently tried it too, and b4 i would do nothing but rail/eat them and only had a few left and figured it would be worth a shot, i was sure i got somthing from it but wasent 100% so i figured id wait till the morning when i was all fiendin out and sure enough it worked rpetty fucking good, prolly a little bit more effective then the same dose raild, i guess technique is key tho.
if u wanna do it get a peice of foil like 2.5 x 5 inches long and fold it in half length wise (using the dull side to put ur shit on, i heard this side is less vaulnerable to alzheimers but it aint changnig the fact ur basing shit off foil) anyways get ur oc out and cut a pill into qtrs, id only wanna use 40's or 80's if i was u since ur just smoking more pill with the lesser doseages, the more oc u put on the longer u want the foil.
anyways keep the oc in large chunks, qtrs work good and put a chunk at one end of the foil about 3/4 of an inch from the edge, grab ur straw or whatever the fuck ur gonna use get a lighter and very quickly run it underneath the pill keeping the foil level while sucking gently with the straw, u prolly dont even need to suck at this point i just do cuz i think im wasting some, after u do that itl be stuck to the foil, tilt it completely sideways to make sure u dont wanna suck up a hot chunk of oxy when ur smokin it, .
now tilt the foil so the pill would melt downward down the crease and start running the lighter up and down the crease where the pill is at quickly moving the lighter a little bit more below it every time u go back and fourth all the time following the pill with the straw, if you did it all right it should leave a black trail and even after holding the hits in for awhile u should still blow out a reasonable ammount of smoke, just make sure to stop the lighter a little bit before hand if ur lungs are getting full since if its still smokin and ur outa room ur not gonna be too happy
anyways thats how its done, it DOES work i have no fuckin idea what the bioavailability might be but it does seem to be slightly more effiecient then raild oc.
