plug it
dissolve a pea-sized ball in 1ml of high grade alcohol, I use 96%ISA, stir ocassionally, leave for a day, it takes a good while to dissolve, so just using water and shaking wont work, and I wouldn't heat it black-tar way.
Next day add 1 ml water draw it into a 2 or 2,5 or ml syringe, lube the syringe (without needle of course) very well, I use vaseline...and well plug the shit, best method of administration, and there's no euphoria in opium compared to H or OC, especially smoking small ammounts, if you wanna smoke an electric weed vaporizer or a meth pipe will do the trick, but I don't get much of a long lasting dope-sickness killing effect out of smoking, plugging large ammounts I got thru a couple of days, my memoy is hazy but I was on codeine and hydrocodone for most of the part I was on opium, maybe that's why smoking it didnt produce a rush, this was a tar sticky substance. Some years ago I smoked dried opium which was way easier to smoke from a bamboo bong mixed with hash, a big pice in one toke and I was really high for more than 90mins, but my opiate tolerance was way lower at that time too.
