CBD crumble is Full Spectrum extract that is CBD rich and has the most potent delivery and activation among CBD vape products. This Crumble is extracted from the highest grade of CBD flower and is in a solid format to be placed and vaped on an open coil vaporizer. The crumble is so potent it can even be broken down, liquidized, and vaped as such and still have its great effects. From Crumble kits that come with an entry level Dab/wax vaporizer to just selling refills of our gold line CBD crumble / CBD Wax, one small piece can contain more active CBD than full bottles of most tinctures. This form of vaping does take a little bit more effort as you have to place the crumble onto the coil which will achieve a handful of good draws, but as anyone who has tried the Goldline CBD Crumble and CBD WAX, it is well worth the vape!
