Hey guys, I recently bought a cartridge from a new plug and he gave me a seemingly burnt cartridge. (I attached a photo of what it looks like) I asked him why it looked burnt and he told me that it was "dark wax". When I hit the pen it tasted slightly burnt (like the end of a cartridge but not as bad). I contacted him after and he told me that "dark wax" tastes like that. To be honest I've never heard of dark wax & I think he's saying loads of shit but I don't want to call him out like that.
The "dark wax" could be a bit burnt itself. It depends how it was made. a burnt cartridge has a different unpleasant taste if you ever burned some you'll probably remember the taste
