There's never been a more interesting time to be involved in the cannabis movement: the world’s first weed-friendly gym is in the works, the once-taboo idea of full legalization is gaining ever-growing support, and the quality of available medicine is improving at an seemingly exponential rate. At the forefront of that uptick in quality have been concentrates. Ever since high-potency waxes and oils were introduced to the cannabis community, extract artists have been working tirelessly to perfect their craft—the result has been a marked upgrade across the board.


With these developments have come a slew of new classifications to describe them—rosin, bubble, full melt; what exactly is the difference? We grab a refresher on the basics and dive in to some of the newer options available to patients today:


Kief: For many patients, kief is the initial venture into the vast world of extracts. Kief is simply resin glands from the cannabis plant containing high levels of cannabinoids and terpenes; the more unacquainted may recognize it as “the stuff that builds up under the screen in my grinder.” It requires no solvent to produce, and has been a staple as a bowl-topper for many years. Kief generally tests around 25 to 40 percent THC.


Hash: Today’s most commonly consumed hash is made by using cold water and ice to separate trichomes from the cannabis plant matter. This method has evolved from ancient techniques such as finger hash—created by simply rubbing buds between one’s hands until enough resin accumulates to scrape off. It can also vary in its consistency and overall aesthetics—it’s been known to be either chunky or granular, and a plethora of colors from light blonde to dark brown. Hash is expected to test from anywhere from 30 to 75 percent THC.


Bubble: Bubble is a term used to refer to a high grade cold-water hash—it gets its name because a proper bubble should in fact bubble when heat is applied. It also incorporates the use of “bubble bags” in its extraction, which further assist in eliminating all unwanted plant matter from your medicine. Bubble hash can be used in conjunction with flower, or alone, in a hash pipe.


Melt: The crème de la crème of cold-water hash is known as a melt (or full melt). These top-quality hashes are, again, true to their name—they should fully melt into liquid when heat is applied, signaling the elimination of all plant matter and/or impurities. Patients who enjoy “dabbing” tend to gravitate toward melts--they can easily be “pressed out” into an easy-to-handle, dabbable form.


Rosin: Rosin is the most recent development for extract enthusiasts—it separates the essential cannabis oils using simply heat and pressure, never introducing a solvent into the equation. Its appearance tends to resemble shatter—a bit tilted toward a pull-n’-snap consistency, with color hues ranging from a nearly-translucent gold to taupe brown. Rosin is usually consumed via vaporization—either in a cartridge or dabbed. THC levels tend to hover between 50 and 80 percent THC.
