Ah, well, there are two ways to interpret this statement.
Yes, Aus. has a syrup with pure dihydro and no other ACTIVE ingred, but it of course has sorbitol, sweets, benzoate preservatives etc. But no other active stuff.
It's called RIKODEINE. It's S3, OTC [no script] but behind the counter. But beware, although dihydro is 1-1.5 times the strength o' codeine
, the syrup can cause terrible cramps and stuff from the sorbitol. Think violent stomach upset, with, well, you know [not vomiting!].
Anyway, there are good tips online about how to clean up DXM
syrups and get DXM base or whatnot.
Basically, as its a salt, wash the syrup with shaking in a coke
bottle with a layer o' zippo fluid on top. This done thrice, it removes some shit from the syrup, but because the dihydro is a salt, it won't follow. Decant the zippo layers using a separating device. Keep the syrup layer below. Then slowly add strongish caustic soda solution to a watered down sol'n of the zippo cleaned syrup, cloudiness should appear, keep drippin' in the caustic soda and alternate with swirling, the cloudiness will form, but with swirling it will disperse. Continue process until the addition of more soda drops do not elicit more cloudiness. Then shake really vigorously for five minutes with new zippo layer. Now the dihydro should be in the zippo layer, separate, but this time keep the zippo. If evaporated now, you will get alkaloid
base with gunk, like propylene glycol and some sorbitol.If you want a better purity, keep the drugged up zippo solution and
a) Shake again but this time with strong citric acid solution, thus drawing the drug
into a citrate salt, then discard zippo. Supposedly, you can then drink this solution, called "agent lemon" but since I never thought it up, I think it's shit, because who knows how much excess acid you would be ingesting?
or b) Shake with hydrochloric acid until hydrochloride salt is formed, then discard the zippo. Then, do the caustic soda thing again and push the freebase out again into a new, clean zippo layer. This cleaner zippo will contain a purer freebase, so separate again, keep the zippo, which can be evaporated and will leave a much purer freebase the second time, compared to the dirty mix that would come straight out of the syrup, I imagine that gunk would be nasty.
Plan B I think is better, because when you make the hydrochloride salt, all that nasty stuff in the zippo oil should be left behind, and any that follows will again face the obstacle of another soda/lighter fluid reversal back to again form freebase.
I have ripped this idea off others
2 It was designed for DXM, and since opiates
have unusual solubility properties/issues, who knows if it carries on to work seamlessly for dihydro as well.
3 I do not know the appropriate strengths of either soda or hydrochloric acid, so this could go wrong and/or be dangerous.
