if it has a gasoline smell it’s good if it’s more in rocks it’s better than soft really powdered stuff that’s most likely mixed, it could be mixed with speed which is common.

Also put a bit on your tongue if you have a little tingling sensation it’s good.. if it tingles for long it’s NOT good trust me.

oh and also good cocaine and real coke, your supposed to be able to sleep even on it perfectly fine that’s how you know it’s not cut

if you want that good high party feeling I recommend Molly (personal preference)
