The cavity created within a cannabis joint or blunt, designed to be filled with concentrated cannabis extracts, is a specialized technique. This technique involves carefully crafting a hollow space, often running the length of the rolled cannabis product. The resulting void is then meticulously packed with hash, rosin, or other similar concentrates. Once ignited, the burning concentrate within this core produces an intensified and prolonged smoking experience compared to traditional methods. An illustration would be the careful insertion of a thin tool to create the central channel, followed by the precise placement of the chosen concentrate within it.
This method provides an enhanced flavor profile and amplified potency, appealing to experienced cannabis consumers seeking a more intense effect. The incorporation of concentrates in this manner can lead to a more efficient use of these extracts, as the burning process is optimized within the confined space. While its exact origins are difficult to pinpoint, the practice likely emerged from experimentation within cannabis culture, driven by the desire to maximize the effects and enjoyment of both flower and concentrates.
