Frankly I doubt it's actually cocaine, there's stuff that's been floating around which is a powder dyed pink and it's usually a combo of ketamine, MDMA, and caffeine that's being called "tussi" or "tuci" (spelling varies as does the chemical composition)
Nobody can really tell you what it is without testing, so I would advise in some good reagent tests to check for those substances and cocaine, having cent strips these days is also a no brainer. Stay safe friend
