Ooooh, bada$$. Is that shatter? You can make it with just heat, or is that the final part of the process? If it can be made without all the volatile chems/petrolium and safely, I'm very interested.
Until a few years ago I had never used any concentrates stronger than hash. The guy I've just started getting my medical herb from does his extractions in some natural healthier way I guess. Very powerful concentrates so whatever he's doing is extremely effective. I used to get it from my former roommates, it was very strong but they used butane. It negatively effected my breathing after only a short time. The shatter I've gotten from the last two delivery services has not negatively effected my health at all.
