Our THC  Weed Wax is about 98% THC and is made with 7X filtered butane.  It was purges on NoGoo sheets and has no harshness at all.  You must have a proper dabbing rig to do weed WAX properly.  You can not roll it in a joint, and you can not smoke it in a bong.  It is possible to use charcoal but you need to be experienced or I wouldn’t suggest it with something so expensive.
