There really is no reason for the amatuer to concentrate cannabis using butane. As mentioned above it really is terrible for your health to smoke any butane residue. Why not keep the process natural. Take advatage of the fact that THC isn't water soluable and buy or make some bubble bags. You can always press it up afterwards to change its texture/consistency.
jimb80 Reviewed by jimb80 on . Which type and how much butane do you use to make BHO? When making BHO what type of butane do you use, how many times has it been refined, and how many ounces? Is triple refined good enough, or do I need to find a more refined one? I saw a 12 pack of 3 oz cans of colibri premium butane for $75. Seems pricey to me but I don't know how much it usually should go for. Plus if I need to use 3 or 4 cans I don't think it would really be worth it. Rating: 5
