Purity - Anyway to purify Ketamine (powder)

[kip]

SWIM ussually gets really good ketamine, however SWIM is always worried about other additives and cuts (if any). SWIM's ketamine does not look like completely crystals, there is some fine white powder which also tastes like K. At times SWIM's nose gets very dry, then then very stuffed up and very gooey, almost like the feeling that a cement brick is sitting in SWIM's nose. SWIM even tries to snort salt/water to wash his nose but it doesnt help.

What swim was wondering is that is there anyway to purify or re-crystalize K so that when he does it he feels safe that it is K and as less of anything else as possible.

SWIM would love it if it came in true liquid form, but it is almost unheard of in liquid form in swim's city.
