do you mean codeine or coke? very strange question mate why would coke have paracetomol in obv i know its cut to fuck nowdays that's why i don't bother with it opiates for me all the way and xanax ..im not sure if the mods will close this.
well cocaine is soluble in water (the hydrochloride salt is anyway, but I think if it's cut with APAP it might not even be cocaine) and paracetamol is not, so dissolving in water then filtering will remove a lot of paracetamol from the coke if you really want to. You'll have to evaporate the cocaine solution in a dish afterwards tho. WHAT IS LEFT IN THE FILTER IS NOT COKE, IT'S PARACETAMOL. THE WATER YOU GET OUT THE FILTER CONTAINS COCAINE.
I get why if you're coke was really cut to shit it's a good idea to get paracetamol out because it clogs your nose and blocks absorption
