Okay so I'm NOT asking for a recipe or ingredients but rather what happens to the ephedrine after the chemical reaction starts inside the bottle? I have seen some people i know use the sake 'n bake method for making meth but none of them really knows what's happening. All they know is, you add so much of this and that and when its done you filter it, smoke it and bob's your uncle.
You take off some oxygen add some nitrogen and remove some water... or something like that.
/closed as no synthesis discussion even though its "educational in nature" it can easily be researched elsewhere... still counts because you cant discuss a reaction without discussing the reaction
