By the way, to answer one of the above questions, I uses hash oil bong loaded with copper/steel wool as a filtering device. I smoke large amounts, usually 35-50 mg at a time for proper breakthroughs. I also, as stated earlier, I uses harmalas as well with the same smoking device. I've also used a small oil pipe with the same steel wool set up. The bong, for some reason, creates better smoke and filtering. Simply put, I've gotten higher on the same amount with the bong.

Hope this helps.
