Bubble hash is a refined hashish that is identified by the bubbles which tend to appear when smoked. The name was designated by the “Bubble Man”, a Canadian innovator who created a hash sieving system that uses ice, water and multiple levels of screens, in order to remove the resin glands from the cannabis, and to remove any impurities from the hashish. This process will leave a very pure resin, with a safer medical use than many other concentrates.
