It could be freebase cocaine, but that shit’s quite rare and you’re unlikely to get sold it without the person making a point it’s freebase as it’d be worth more then cut coke like what you normally get. Can you take a pic of it and post it here? Depending on how the crystals are formed it might help me work out if it’s even either of them two substances. (I’ve known of people getting sold ketamine as coke before so you’re right to be concerned, in fact it’s happened to me once in landzaroti, luckaly I worked out what it was before snorting it or that would of been one horribly messy night).
The likely hood is that it’s meth though I would guess, but not having looked at it (or more tried it) it’s harder to tell.
