More and more THC and Delta 8 THC users are turning to concentrates.

One of the more interesting trends to pop up lately is cannabinoid-rich rosins. They’re some of the most aromatic cannabis extracts available — leveraging the powerful benefits of cannabis-derived terpenes.

Learn what rosin is, how it’s made, how to use it, and why rosin is the future of cannabis.


Rosin is a waxy, pasty extract containing high concentrations of different compounds in marijuana or hemp plants. It’s made without solvents and can contain THC, delta 8 THC, CBD, terpenes, and more.

There are basically two ways to extract these compounds from marijuana and hemp plants: heat under pressure and solvents. Solvents include alcohol, oil, vegetable glycerin, and other compounds that naturally pull THC, delta 8 THC, or CBD out of the plant material.

There are many ways to complete the extraction using solvents, but rosin is specifically made without any solvent. Instead, the plant material is placed under very high pressure and heated — which is the same process used to create diamonds and minerals.

Rosin is the liquified resinous mixture that’s forced out of the marijuana or hemp flower while under extreme pressure.


Rosin is made from pure marijuana or hemp flower. The fresher, the better.

Depending on the temperature and pressure used, the rosin can contain concentrations of THC up to 80%.

Terpenes will also naturally be included in rosin, as will trace amounts of other minor cannabinoids. These compounds are normally lost in the extraction process from high heat or the use of caustic solvents.


Most individuals who make their own rosin use a device aptly referred to as a “rosin press,” which is a hydraulic or mechanical press with heated pressing plates.

Generally, rosin comes from pressed marijuana or hemp flower, but it can come from kief or hash as well.

Before pressing the marijuana or hemp flower, it needs to be enveloped in 35-pound parchment paper to prevent impurities and plant matter in the finished product.

The heated pressing plates then compact the parchment-wrapped flower at a consistent heat and pressure. The rosin is eventually forced out of the flower and scraped off the parchment paper.


You can make your own rosin, but you’ll need cured marijuana or hemp flower, rosin parchment paper, and a rosin press. Presses can be quite costly, so most people just buy their rosin instead.

Some individuals make a makeshift rosin press out of a hair straightener and a woodworking clamp. The process is similar to using a dedicated rosin press: you use the hair straightener plates as a heat source and clamp them together to create high pressure.

As you might expect, the results are much less consistent, and the yield is much lower than if you use a rosin press.


Most commercial rosin is between 75% and 85% THC. For comparison, marijuana flower from dispensaries is usually between 15% and 25%, depending on the strain. As such, rosin is about four times as potent as marijuana flower.

Homemade rosin varies wildly in purity, especially if you use a homemade press to make it. You can reasonably expect around 40% to 60% purity for homemade rosin.

The amount of THC in rosin by weight depends on the plant used to make it. For example, medical strains that reach THC levels of around 30% will naturally produce rosin higher in THC content. Strains around the 15% THC level produce less potent rosin.


Rosin needs to be heated to convert the THCa to THC, which produces the psychoactive effects. The most common way to consume rosin is to smoke it or vape it, but some people make edibles with it instead.

Most people use a dabbing rig to enjoy their rosin. The bowl is heated to the desired temperature, and then the user inhales through the mouthpiece while placing a small amount of the rosin wax into the bowl. A bowl cover — usually called a carb cap — is typically used to direct airflow around the bowl to ensure all rosin is heated and consumed.

Some users simply add a small dab of rosin with the flower or in a bong, pipe, or bowl. Others roll small amounts of rosin into joints or blunts before smoking. The rosin heats up with the flower right before it’s inhaled.


It’s best to store rosin in a small, air-tight glass container. Standard rosin containers can hold up to about a gram at a time, maximizing freshness and minimizing the amount of air that gets into the container. Exposure to the air gradually degrades the rosin, making it less potent and stripping it of its valuable terpenes.

Most regular users store their rosin at room temperature without any significant degradation, but those who use rosin less frequently will find that it’s best kept in the fridge and thawed to room temperature for use.

You can freeze it for long-term storage, but you’ll likely notice some degradation over time. It’s important never to open a frozen rosin container until it thaws, as condensation can form inside and cause the rosin to rot prematurely.


There are a few different types of rosin, depending on the plant material from which its extracted. Rosin will almost always contain multiple cannabinoids and terpenes, but three primary types are named for the main constituent.


CBD rosin has high concentrations of cannabidiol (CBD) and is made by pressing high-CBD, low-THC strains of hemp flower, which legally contains less than 0.3% THC by weight.

CBD rosin can reach potencies of up to 85%. Additional minor cannabinoids and a wide variety of terpenes will usually be present in the final product.

Most CBD rosin users consume it for pain relief, to aid in relaxation, or to help them sleep.


Delta 9 THC — commonly referred to as just “THC” — is the principal psychoactive constituent in marijuana. As you can imagine, delta-9 THC rosin is usually made with a potent high in mind. This rosin has the same benefits as THC but with more powerful effects because of the extra terpenes and minor cannabinoids present in the final product.

Manufacturers make delta 9 THC rosin by pressing marijuana flowers or kief collected from marijuana plants.

The potency of this rosin typically falls between an impressive 75% and 85%, making this one of the purest ways to consume full-spectrum THC.


Delta 8 THC rosin is different from Delta 9 THC and CBD rosin, solely because Delta 8 THC appears naturally in hemp and marijuana plants in very minimal concentrations. Instead of pressing pure plant matter, most manufacturers spray hemp flowers with a delta 8 distillate before pressing the rosin.

Therefore, delta 8 THC rosin is less potent than delta 9 rosin, often between 60% and 75%.

These products offer all the benefits of Delta 8, plus the addition of CBD, terpenes, and a long list of nearly 100 minor cannabinoids rarely included in Delta 8 THC products.

The experience from a high-grade delta 8 THC rosin is nothing like standard delta 8 products. It feels clearer, more mellow, and less likely to make you feel groggy the following day.


Many THC and CBD users confuse rosin and live resin because of the similar name and the appearance of the product.

There are a few key differences between the two; the most important is the production method.


Manufacturers make rosin by introducing marijuana or hemp flower or kief to high pressure and heat. It’s considered a more natural product than most others since its production doesn’t require solvents or chemicals.

Live resin is made by cryogenically freezing plant matter after harvesting. Then butane or propane is used to extract the desired compounds — delta 9 THC, delta 8 THC, or CBD. Although the process removes the hydrocarbon solvent before sale or consumption, live resin is considered less natural than rosin.

Individuals without advanced equipment can make rosin with household items or by purchasing a reasonably inexpensive rosin press. Live resin is almost impossible to make at home without thousands of dollars of high-tech equipment.


Taste is another crucial difference between rosin and live resin. Rosin naturally contains terpenes, which contribute to the flavor when smoking. Most users report that rosin tastes better than smoking flowers.

Unfortunately, the heat needed to make rosin can damage some of the terpenes. There’s still much more than a standard cannabinoid extract, but live resin still takes the win in terms of total terpene content in the final product.


Finally, rosin and live resin differ in cost.

Rosin production only processes a small amount of flower at once, whereas the live resin process is generally cheaper and makes larger batches at once.

You can expect to pay about 10% extra for rosin products with the same equivalent in cannabis flower as you would with live resin.

Live resin isn’t exactly cheap either. These products cost an average of 20% more than standard cannabinoid distillates.


The legality of rosin varies from state to state with the marijuana and hemp laws, and it also depends on the type of rosin.


CBD rosin is federally legal, provided that it’s from hemp plants. The 2018 Farm Bill legalized hemp production, manufacturing, and the sale of any products containing constituents of legal hemp plants.

However, CBD laws vary from state to state. CBD rosin is legal in any area where CBD is legal. Some states have banned CBD altogether, while others have restrictions on its sale and production. The legality surrounding CBD rosin is subject to that of CBD in your state.


Similarly, delta 9 THC rosin is legal in any area where Delta 9 THC isn’t prohibited. Marijuana is still illegal federally, so products containing delta 9 THC, including rosin, are illegal as well.

However, all states have their own laws surrounding THC. If your state permits recreational marijuana, then you’ll have no issues buying, possessing, and using delta-9 THC rosin. If THC is only legal for medical patients in your state, then you’ll need a medical marijuana card to buy and use Delta 9 THC rosin.


Delta 8 THC extracted from hemp plants is technically legal on a federal level. However, your state’s local laws can vary, so you should check to see how Delta 8 THC is governed in your area before buying, carrying, or using Delta 8 THC rosin.


Rosin is a solventless extract taken from either marijuana or hemp plants. It contains high concentrations of delta 9 THC, delta 8 THC, CBD, or some combination of these three major cannabinoids. It also typically contains various natural terpenes that enhance the flavor and minor cannabinoids that contribute to the effect profile.

Rosin is made by introducing marijuana or hemp flower or kief to high pressure and heat. The resulting extract can be stored at room temperature or in the fridge to preserve purity or in the freezer for longer-term storage.

Most rosin users smoke the product using a dabbing rig, but many use it with other smoking apparatuses, like a bong, pipe, bowl, joint, or blunt. You can also add rosin to your vape as long as it’s set up for concentrates.

Rosin is considered one of the purest extracts possible. It’s regarded as a premium product and often fetches a relatively high price. Its legality varies from state to state, depending on local laws and the cannabinoids contained within it.


When you vape cannabis, what are you actually inhaling? Live rosin separates itself from other capable because of what’s in it—and what isn’t.

Most vape cartridges on the market are essentially vessels for delivering THC, CBD, or a combination of the two. But cannabis is so much more than its two most famous cannabinoids. The plant contains over 100 cannabinoids and a suite of terpenes, which provide much of the character and flavor of a strain. What ends up in the vape cart is a result of how the cannabis flower is extracted, and if you want to translate the full complexity of the plant into the mysterious goo in the glass cylinder, you need to use a specific, meticulous process.

Turning the trichomes into the viscous liquid that goes in the vape cart is where many producers introduce a solvent. For instance, live resin (not to be confused with rosin) typically uses butane or a similar hydrocarbon solvent to pull out hash oil. It’s efficient for production purposes, but nearly impossible to guarantee that no residue remains to be inhaled by the end user.

To meet the atomization of large-capacity (>1.0ml) rosin liquid, for atomization equipment, it is necessary to control the output power and voltage. Usually, the output of the battery voltage is controlled between 2.8-3.2v to maintain stable power output. Further research needs to improve the atomizing core so that it has a larger oil inlet aperture and the ability to lock rosin liquid so that the atomization and oil conduction speed can be balanced.
