As cannabis concentrates explode in popularity, more smokers are wondering what bubble hash is. While the history of hash stretches back many centuries, learning how to make bubble hash is a relatively new process discovered in the 1980s. Its purity and potency popularized it with the cannabis community at the turn of the millennium.
Today, bubble hash is another mouth-watering option for stoners who love potent puffs. Because it doesn’t use solvents, its popularity is on the rise with concentrate connoisseurs who want pure puffs packed with THC.
Bubble Hash Basics

Bubble hash is an extract with a cookie-dough-like texture that bubbles when you smoke it. Instead of using solvents to separate trichomes from cannabis like shatter or wax does, it uses ice water. This process freezes the cannabinoid-rich trichomes, breaking them free from the plant. After separating the cannabinoids from the flower, bubble hash is what remains.
Because heat was not involved when discovering how to make bubble hash, the characteristics of the original cannabis strain are more present, making it high in THC, cannabinoids, and terpenes. These chemicals preserve the flavor, aroma, and effects of the original strain used to make the hash.
You can sprinkle it inside joints and on top of bowls to bolster the THC of your smoke sessions or dab with it for incredibly potent puffs. Lower-quality hash is also an excellent option for infusing THC into your favorite recipes.
This extract is an excellent choice for wellness-focused smokers who want to avoid solvents and those who seek a more full-spectrum experience from their smoke. The unique highs from each strain come as a result of these terpenes and cannabinoids working as one.
The Different Grades of Bubble Hash
Not all bubble hash actually bubbles when it’s vaporized. Only higher-quality hash produces this effect. Like any other extract, the process and materials used to make hash lead to its effectiveness. The following rating system helps denote the quality of hash to help stoners understand what they can expect from their extract.
One Star
The lowest rating is one star, signaling higher levels of plant material in the hash. This concentrate is usually made from lower-quality cannabis and is filtered using larger screens that let more matter through during the straining phase of production. It might not bubble and will not melt.
Two Star
Generally considered a cooking-grade hash, the two-star rating still indicates that plant material has made its way into the extract. While it won’t do much for anyone interested in dabbing, it’s a solid option for cooking edibles or sprinkling over the top of a bowl or joint.
Three Star
Also known as “half melt,” a three-star hash will still leave behind trace amounts of materials after heating. It works with a dab rig, though it won’t yield the best results. We recommend that hash of this quality remain the domain of edibles or flower toppers.
Four Star
At four stars, bubble hash reaches a point where it becomes a viable option for dabbing. True to its name, this extract will bubble. While it still leaves residue behind, it also captures more of the taste of the original strain.
Five Star
Also known as ice wax, five-star hash is great for dabbing. It unleashes deep flavors that are true to its original strain with a very high level of purity and potency. It will leave behind residual oils and traces of contaminants.
Six Star
Six-star hash is known as “full melt” due to the lack of residue it leaves behind. This extract is the highest quality of bubble hash and is best when dabbed, as it provides a full-spectrum smoking experience that is incredibly pure and wildly potent.
How to Make Bubble Hash

Now that you know what bubble hash is, you might wonder just how easy it is to make. While it does require some specific tools and a little time, learning how to make bubble hash is surprisingly easy. Before you begin, be sure you have your favorite strain, bubble bags, two 5-gallon buckets, a long stir stick, and a bag of ice.
- Fill one bucket with a layer of ice. Then, add cannabis and an additional layer of ice on top. Add water to the bucket until the ice and marijuana are covered. Let the mixture sit for 20 minutes.
- In the other bucket, layer your bubble bags so the coarsest mesh is on top.
- Stir the weed/ice mixture for 20 minutes. Then, pour it into the top bag in the second bucket.
- Slowly pull up each bag so the water flows through the mesh to the next bag. It might be necessary to give the bags a slight squeeze.
- After it’s completely strained, spoon the wet bubble hash onto a sheet and allow it to sit and dry for three hours.
- Shape the hash into balls. Let them dry for an additional two days before using.
