Too bad you don't live in the states, I'd recommend CannabisMedicineOnline. I wouldn't be dabbing that shit if I were you but I definitely have been there where you don't wanna waste your money. Too bad.
Does the shatter leave white residue on the inside of your banger? I heard that a lot of dab manufacturer's in Canada are cutting it with pine resin to increase profit. If it leaves white residue, it's pine resin.
