The oil is a piece of piss jay, depends if you want the oil for e-cig machine or oil for smoking, if its just for smoking get an empty bottle and fill it with ground up trim or buds if you have lots to spare, and put a coffee filter over the mouth of the bottle when its full, hold it over a Pyrex bowl and empty a full can of zero impurity's gas through the bottle ( make hole and pour in gas at bottom of bottle ) make sure you do this outside away from naked flames and no smoking or heat, after the bowl is full of liquid gas get a bigger bowl of hot water and allow the bottom of the pyrex bowl to sit in the hot water this will cause the gas to evaporate leaving behind only the thc, when you only have thc oil left smoke away or spread it on a paper and roll a jay and you will be flying, if you want it for e-cig machine like me add a few ml of propylene gyycol ( couple euro online ) and keep over the hot water until the two oils mix, once mixed fill your e-cig machine with it and vape away like a moe foe! powerfull brew i tell theeday off today for a long weekend and what a day it is!!Mdjenks id love to head to denver its somewhere i need to start saving for!
