apparently you are wrong about the absorbtion. My friend just got out of county and had meth served to him in this fashion. amazing how much you can fit on a greeting card. We dissolved 7 grams into 20ml of water, then soaked the card and let it dry... it looked just like it did before we bought it, but it had gained some weight(not overly heavy, just felt like nice card stock). I was just an observer in this experiment. Not my meth, so I had nothing to lose, though my friend was pretty worried he just wasted it at first, but after it dried nicely, he was happy. I spoke to some other people with experience doing this, and they mentioned that one thing that is very important is to use pure water to dissolve, not tap. RO or distilled water only. If you use tap, the minerals and shit in the water end up streaking and helping the crystal crumble off the card.
