Well that's not quite enough information to give a detailed answer but I can give you common problems associated with Cocaine. For starters it's a corrosive alkaloid that often perforates the nasal septum along with damage to turbinates.
The common cuts these days range from levamisole to fent. Levamisole being an anti parasitic agent, pseudo-ephedrine, caffeine,mannitol ,Chalk ,Talc, Ascorbic acid, Quinine, Boric acid, Laundry detergent, Laxatives, Meat tenderizer, Lactose and other sugars, Plaster of Paris, Creatine,
Pure cocaine is a more relaxing high but with other stims added to it the urge to redose is greater so methylphenidate, regular amphetamines, methamphetamines (as it's cheaper to bulk up with these rather than transport more pure Coke from Columbia), then you have the numbing agents to make it seem "real" such as benzocaine,lidocaine, xylocaine. Maybe yours only has 3 or 4. Maybe it has 12?
Another problem is the RC market and the cheap stims like the ones used in bathsalts. Cartels stocked up a long time ago and analogs are available like Rt-113 ,3β-phenyl ring substituted analogues ,2β-substituted analogues ,N-modified analogues of cocaine ,3β-carbamoyl analogues ,3β-alkyl-3-benzyl tropanes ,6/7-substituted cocaine ,6-alkyl-3-benzyl tropanes ,piperidine homologues of cocaine, it's a different ballgame these days.
