The 2 main methods are:
* mixing with a small amount of water and snorting
* mixing with a small amount of crushed tablets (I think OTC sleeping pills, like Unisom, are often used)
OBVIOUSLY, the second option is NOT ADVISED, as there could be problems with synergy making one TOO sleepy, and often using tablets, one actually makes absorption MORE difficult, from the binders found in the tablets.
One could take the spirit of the 2nd option, and mix it with an inert powder (flour? sugar?) to make it "snortable".
I know someone who mixes a dose up as if to inject it, pulls it into the syringe (one should break off the needle first) and then squirts it into the nostrils to be absorbed by the body there. One has to use a lot less water than the "usual" way of mixing with water, from what I understand. This method could also be used, but instead of up the nostrils, it could be put up the anus, for even better absorption. If unable to get syringes OTC in one's area, an "oral syringe" or "infant syringe" should easily be found in the baby care aisle - it's a syringe without a needle meant for giving children a dose of medicine.
Just thought I'd throw in another option.
It's said that the "tar heroin
" comes in a hard, brittle form that crumbles? I don't see why a small amount of this crumbled tar couldn't be snorted, though it might be suggested that not too large an amount is used, and to not sniff it too hard, as one would want it to melt in the mucous membrane, not the back of the throat.
Why not ask SWIY to try it a bit before smoking the next batch and see report back to the forum on if it worked or not?
I don't know if it is warm enough inside the mucus membrane of the nostril to "melt" and thus be absorbed efficiently. That said, if one were in the same position, one would give it a go, just to see.
