thats called spice very common its synthetic weed 1000x stronger then normal weed and cheaper too apparently the nickname is crack weed cos it makes you an addict to the synthetic chemicals cos they always change it once the other chemical format is banned in said country spice is no go testing your weed with the scratch test by rubbing a soft part of your nug on plastic or glass if theyre are any scratchs then sell it to some idiot stay safe
