Snoke, I have used lemon juice, vinegar, kool aid, and the best and safest method is pure vitamin C powder/water, but only when injecting crack. I do not know if putting it on a plate and microwaving would cause it to evaporate back to regular cocaine HCL and be snortable... I wouldn't risk it as I am an IV user. To prep it for iv I normally only use lemon juice to break the crack down(usually the only thing I have available to me) about 50 units worth for around regular sized 20 piece more or less, stir it in a spoon, then add about 30 units of cool to room temp water. It works well every time for me, but MAKE SURE you do not miss. I have missed before with this method and it sucks, burns like a bitch and ruins your veins! If you are not an experienced IV drug user I would advise against doing this, and try to find some powder coke instead. I usually 90% of the time smoke my crack when I have it, because its so risky to shoot, unless you have the pure vitamin C powder/ mixed with water, that is the safest way to do it, but still not totally safe by any means, also try to use a micron filter if doing this. To me it sounds like you prefer snorting coke though and even if you were to find a way to change crack back to cocaine hcl powder, you wouldn't yield nearly as much from a 20 piece of hard compared to a normal 20 bag of powder... This is just how I do it and it always works and gets me stupid high... but like I said if you aren't super experienced with the needle don't do this, smoke it or find powder.
