Could be anything - folks have had 30 plus years to figure out how to cut cocaine. I learned to reconstitute it so that the rocks looked great. We were nasty folk back then, the rocks were cut up - we sprinkled a little pure around so that folks would taste the pure and figure that the rocks must be as pure or purer - we knew they would save the rock and sell the duff. This is the sort of crap that coke eventually invites you to do. If it gets you pleasantly high, great, if not, coke is pretty much a waste of time, money and nasal passages - have fun.
