wow, i wish i could just walk down the street to the headshop and buy methylone. that must be so awesome
assuming the methylone is in its acid salt form and not the base form (its probably in the salt form), u could try washing it with a nonpolar solvent (no i dont mean acetone (nail polish remover) or isopropyl alcohol, i mean real non polar solvent) you could possibly use naptha (can be bought at home depot and a lot of other places). if you use acetone(nail polish remover) or rubbing alcohol , you will wash away a lot of the good stuff. acetone is still polar, just less so than water. Or maybe use some methylene chloride or something like that. This will remove any non polar stuff in the binder.
if the binder is mostly insoluble in this nonpolar solvent, then it likely can only be washed away using a polar solvent. This will make things a bit harder. Because then you may have to do a full blown extraction (not quite, but same principle as dmt extraction). you would have to convert the methylone to its free base form by dissolving it all in some water, add some naptha , and adding some sodium hydroxide (easily bought at home depot, use Roebics 100 percent lye, may even be sold at a few convenient stores if your very lucky.The methylone (if its like other amines that are like this (dmt , mdma, meth, etc) ) , will leave the water solution and dissolve into the naptha. Then you can take some pool acid, pour it into another plastic soda bottle , and attach a plastic tube to the top of it. then drop the other end of the tube down into the naptha . squeeze the bottle to let acid fumes enter the naptha, the acid will convert the base methylone back to its salt form. As this happens, methylone hcl will precipitate out of the naptha, filter this and dry it.
Dont cut corners and use acetone wash or something like that, you will seriously wash away a lot of methylone if you do that.
if your planning on snorting it, which it sounds like you are, then make sure its the best ROA for methylone, because it isnt for MDMA. if your planning on injecting it, be sure to do the above method right or not at all, cause if you fuck up and somehow get sodium hydroxide or pool acid into the final product, it could be pretty bad.
yea, it sounds like a lot of work.
