MDMA Crystal - 100% or 84% purity?

Off topic but I think most drugs cant be 100% because you have to stuff in for example like Cocaine which has something added to make it more compact for transportation, So Cocaine can never be 100% when it reaches UK..... if it ever did reach here in it compact original form.

Same goes for heroin, I think, i think certain things makes it be able to run on foil, which is why some gear cant be smoked.

Im probs wrong, but hey ho.


BUT the main point is, you can make more money cutting, so who cares about 100% =D
 
I think UK heroin is Afghan # 4 which is cut with caffine because it is mainly smoked. Nearly all cocaine is cut with manitol before it leaves South America aswell you are right.

MDMA isn't only 84% cos it's cut though and that is not the max % pure you can get it to either. It's because they're producing so much and it's already quality stuff at 84% they're not going to the enth degree of washing it like someone who was passionate about taking it themselves might. I've seen crystal that's white/clear from Holland and it was stronger mg for mg. Seen reports of MDA from Canada on another site being 90% aswell, so it is possible.

I dunno, I understand that you'll get people who can't make Ecstasy making pips etc but I wonder if once you'd spent god knows how much setting up a lab and getting the ingredients in from the forests of cambodia you'd be happy if the chemist turned to you and said "Well, I think it's something like E mate". Wouldn't you look round for a decent chemist before you travelled to cambodia?

84% is still quality MDMA. It's the % most of the silvery dutch crystal that's around the UK just now is. Also these people setting up the labs are not travelling to cambodia, it's more likely the PMK is being sent over, probably arranged through import/export deals between Dutch and Asian gangs. I'm sure if you had the right sources you could probably find it online tbh. Also I'd imagine the purity you get in the end depends alot on what lab equipment you have available. Sure if you had a legit purpose for having a lab rather than just a shadey set up for producing class A drugs, it would be alot easier to produce really clean stuff.

It depends a lot on how it's made. The "first form" ie the point when you first have MDMA from your synthesis is an oil dissolved in a solvent. You then bubble HCl gas through this solvent, which causes insoluble MDMA.HCl to form, which precipitates and sinks to the bottom.

Larger crystals can be gained by adding water to these small crystals and allowing it to evaporate slowly.

A question I have: surely the bubble precipitation should carry very few precursors into the precipitate, since these aren't amines? Why is it then, that the shards often seen in street MDMA tend to have a fairly large amount of brown impurities, easily recrystallised out with acetone?

Re-crystallised with acetone? You need to dissolve the MDMA in a suitable solvent to get it to re-crystallise. Acetone isn't suitable as it is non-polar. Acetone wash will remove non-polar impurities after re-crystallisation.
The bubble precipitation (bubbling HCL through MDMA base) causes HCl to react with other reactants it comes into contact with as well as MDMA. The MDMA base will not be pure at this point, therefore other products are possible, hence impurities (I'm guessing, but it's a good guess).
It would be better to distil the MDMA base upon initial production and then react with HCl later if purity was of the essence. Alas, this is rarely the case and adds complexity and cost for a few % points of purity.
 
Some semi-dodgy MD from London on NYE. Still feeling shite. but I must have had the guts of a gram over 6-8 hours :/

Lots of throwing up and spaceyness in waves between the goodness. Reminded me of crap times on those RCs like MDAI and MDAT.

It was off white and had a saltier taste than pills/other md with the bitterness coming after.

You can do a good recrys with acetone, get it hot and it works just fine as a solvent.

It is a good guess, but the idea is that the bubbling causes only the very fast acid/base neutralisation to give the salt. Non basic side porducts and reagents should only react a minimal amount, and even if they do, aren't necessarily insoluble in the solvent so shouldn't really be present in the crystals.

What I think is happening is that a different method is being used to get the final solid. the large shards must be grown relatively slowly, and redissolving and evaporating a fine precipitate wouldn't keep these impurities unless it was deliberate. I guess the bulk MDMA chemists of the world probably don't spend much time on BL, so maybe I won't get an answer at all!

I know MDMA.HCl is highly insoluble in Acetone at room temp and Acetone boils at 56C. Can you get it to fully dissolve before boiling? Never seen it referenced, but I see in theory it could work nicely if it fully dissolves before all the acetone boils off!
 
I've only done it once, and did not bother to fully dissolve the MDMA, but yes, it did exhibit some solubility and gave a fine powder as the result. with 100mls+ per 1g I think it could be done.
