Hey guy's, just a quick question. I use the "china white" type heroin that's like barely off white and its in rock form. I just boil some tap water and draw it up in my syringe then let it cool. I put the heroin in the spoon and squirt the water on the heroin and it turns brown and literally dissolves as i squirt the water over it.. I'm left with crystal clear water with a copper color tinge to it.. I then filter it by drawing it up through a small pre wet tight small cotton ball through the syringe. And there is NO residue left on the cotton.. Question: Do I Really Need To Use a Wheel Filter? I just feel like it's so clean due to the "no residue" on the cotton that a wheel filter isn't needed.. Or do I need to wheel filter it every time? I just feel like i'm losing some of the drug if i do. And when I try to pre wet the filters they tend not to work after that idk why.. anyway guys and gals thanks for any input! sorry for the long post I wanted to be detailed. 8)
