I made this oil using butane ~ VERY DANGEROUS AND I DO NOT ADVISE YOU TRY IT~ right, the warning over, its the same as ISO more or less, it ends up with the same product ~~ here is what i do~~~~ I get the resulting product and it is EXTREMELY POTENT ~~ I mix it with 75% pure virgin olive oil and 25% hash oil, I then have a liquid mix, this mix is used to to cook with mostly, but I have a tip for you cigarette smokers ~~ take a matchstick or similar blunt ended item and dip it in the oil, you then dab it down your cigarette making oil spots on it, the oil soaks in the paper and tobacco and as you walk the street, your smoking a 'normal' cigarette, understand what im getting at?
