More information on how to make drugs safely is better for everyone.

Firstly i'm glad to find someone interested in manufacture and Harm Reduction as i'm myself heavily involved in Harm Reduction at my little level.
But about manufacturers i'm not sure the majority are all full of good intentions. What to think about Dutch moonrocks who are brown like shit smelling sass and full of byproducts, making users sick; or even if it's a cut about cartels who are cutting cocaïne with levamisole at pasta to Hcl labs level to synergize the effects, and not giving a damn about  health consequences (i will post sources about effects of levamisol on health later if people are interested). BTW if people know a way to remove levamisole simply and i insist on the simply (a little bit like the acetone wash for some of the others cuts) I will be happy to learn it and then share it to users around me.
But yes Harm Reduction Should works towards manufacturers too I totally agreed with you.

Vesp:
Wow that levamisol thing is really interesting! We should definitely talk about an easy way for people to detect and remove it.
Perhaps a kit exists already to detect it?

zekoner:
yes i think EZ test a dutch company sell a kit to detect it and i remember seeing somewhere a receipe to make your own i will post it here when i will find it back. Nowdays it is something like 80% of seized cocaine who contains levamisole and sometimes at rates like more than 20% check the energy control website (spanish harm reduction association) they have some analysis of cocaine with up to 22% of levamisole inside if i remember well.
As you seems interrested in the hours coming i will be posting all the informations i get.

edit

so here is the recipe for levamisole test kit http://www.thestranger.com/seattle/levamisole-test-kit-recipe/Content?oid=6854940 BTW in the links there is a very good article about this new trend it's named the mystery of the tainted cocaine.

the why levamisole https://www.ncbi.nlm.nih.gov/pubmed/24440755

too speak effects of levamisole the most common secondary effect is agranulocytosis. To have much info on levamisole secondary effect hit Pubmed.

Impossible:
Levamisole base is far more solublein hexane than the cocaine freebase.

Multiple water/hexane washes of freebase, discarding hexane layers, is shown to effectively separate the two compounds.

myhero:
discarding hexane? From reading it seems that Cocaine base is soluble in hexane and it's the water we need to discard.


--- Quote ---For mixtures of cocaine base/tetramisole base, the best method to purify the cocaine was a liquid/liquid separation employing hexane and water; five water washes suc- cessfully removed tetramisole base from the cocaine.
