Full Spectrum THC: What Is It & How Does It Work?
November 01, 2023
There are a lot of products on the market that claim to be full spectrum, but if you’re not purchasing the product from a dispensary, it’s likely not a full spectrum cannabis product. To be full spectrum, an extract has to have all the cannabinoids, terpenes, flavonoids, and additional compounds natural to the plant. How’s that possible? In this guide, we’re going to give you the details, ensuring you know what full spectrum THC is, how it’s made, and where you can get it.
What is a Full Spectrum Extract?
A full spectrum cannabis extract is a cannabis concentrate that has preserved the compounds found in the marijuana plant. Not only will you have THC and CBD in a full-spectrum extract, you’ll also have terpenes, minor cannabinoids, flavonoids, and other compounds that are natural to marijuana.
Because these compounds are so delicate, the full-spectrum extraction process is a careful, precise procedure that inevitably increases the cost of the final product you find on the shelves of your dispensary. That said, you’ll also have one of the most aromatic, flavorful products you’ve ever experienced outside of pure marijuana flower.
How Does Full Spectrum THC Work?
To understand how full spectrum THC works, you have to understand your body’s endocannabinoid system. We used to think that THC is what caused the potent effects that we feel when we consume marijuana, and it’s true, THC does contribute to those psychoactive feelings we get. But in 1988, a researcher named Raphael Mechoulam suggested that the other compounds found in cannabis, including other cannabinoids and terpenes, may also have an effect on our body, and when those compounds are paired with THC, we get a unique experience. This theory was coined the entourage effect.
Full spectrum THC embraces the theory of the entourage effect by keeping all the cannabinoids, terpenes, flavonoids, and other compounds in marijuana that are natural to the plant. That way, we can experience the plant in its entirety and not just specific facets of the plant—like a single cannabinoid. This whole-plant experience is unique to you and your endocannabinoid system.
How is Full Spectrum Cannabis Oil Extracted?
There’s no question that full spectrum cannabis products require a little extra time and finesse in order to preserve the cannabinoids, terpenes, and flavonoids in the final product. Because of this, the techniques to create a full spectrum cannabis oil are limited to three types of extraction:
-
Hydrocarbon: When butane or butane and propane are cooled, liquified, and pushed through marijuana, they can remove all the compounds we love that are found in cannabis. Then, those solvents have to carefully be removed (along with the fat and wax) to ensure a clean, final product. This time consuming process has to be precise to ensure none of the terpenes are destroyed.
-
Supercritical CO2: Replace butane and other solvents with supercritical CO2, and you get this unique form of extraction. Supercritical CO2 acts like both a liquid and a gas, getting into all the nooks and cellular crannies of marijuana. Then, the temperature and pressure is gently adjusted, causing the CO2 to pull the compounds we want out of the cannabis.
- Heat & pressure: For cannabis enthusiasts who don’t want to have solvents touching their full spectrum extract, heat and pressure can do the trick. The marijuana plant is put through a process like ice water extraction or dry sifting, which removes the trichomes from the plant. Then, heat and pressure are applied to those trichomes, and the result is a flavorful, aromatic, full spectrum extract.
Full Spectrum THC vs THC Distillate: What’s the Difference?
The biggest difference between full spectrum THC and THC distillate is what is in the final product. A THC distillate is just that—marijuana that has been distilled down to just THC. In most cases, THC is the only cannabis compound you’ll find in the extract. Full spectrum THC, on the other hand, preserves all the compounds in the cannabis, including the THC. In general, if you purchase a full spectrum product at a dispensary, it will be considered a full spectrum THC product.
What Products Have Full-Spectrum Cannabis Extract?
Full-spectrum cannabis products contain all the cannabinoids, terpenes, and flavonoids you’d find in flower. The extraction process prioritizes preserving these important compounds. If you’d like to enjoy a full-spectrum cannabis extract, you should try:
-
Flower: Flower, obviously, is a full-spectrum product. That said, it can be used to create full-spectrum extracts too. These extracts include live rosin, which is flash-frozen cannabis that is put through a solvent-based extraction to preserve all the compounds we love about cannabis, and ice water hash, which is a hash made from trichomes that have been dislodged from flower via an ice water agitation bath.
-
Edibles: While edibles can be made from things like THC distillate, which is simply THC suspended in oil of some kind, they can also be made from full-spectrum products. Cannabutter, for instance, is typically a full-spectrum product because the only thing strained from it is the seeds and stems. One thing to remember, however, is that if you cook with a full-spectrum product, it’s possible that you could destroy some of the terpenes in the product in too high of heat. It’s also likely that your edibles will have a stronger marijuana flavor because those terpenes pack a sensory punch.
- Topicals: Cannabis topicals are exactly what they sound like—a topical product applied onto the skin. You can find topical CBD and THC products that focus on that single cannabinoid, but you can also find topical full-spectrum products, including lotions, salves, creams, and balms. These products preserve the terpenes and cannabinoids in the cannabis, allowing all of those compounds to work together on the endocannabinoid receptors found in the skin.
Answering FAQs About Full-Spectrum Extracts
Full-spectrum extracts are becoming more and more popular with curious cannabis enthusiasts that are interested in a flower-like experience without the hassle that comes with enjoying flower. Because of this, we get a lot of questions, and here are just a few of them along with their answers:
Does full-spectrum CBD have THC in it?
Most full-spectrum CBD products have at least a small amount of THC in them, otherwise they’d be called “broad spectrum.” With products sold outside of a dispensary, they have to have less than 0.3% THC. Unfortunately, these products also tend to be unregulated. If you purchase full-spectrum CBD in a dispensary, you’re getting a safer product that will likely have more than 0.3% THC in it.
Is full spectrum more potent?
Full-spectrum products are not necessarily more potent. They tend to prioritize preserving the cannabinoids, terpenes, and flavonoids in marijuana. Because of this, the manufacturers are less focused on jam-packing their products with THC. That said, a lower THC potency doesn’t mean the product won’t hit you hard. The entourage effect can be a powerful thing, and all those compounds working together with your endocannabinoid system can create some powerful results.
Can you dab full spectrum extract?
Dabbing just means that you’re using a dab pen or dab rig in order to consume your concentrates. You absolutely can dab full spectrum extracts, like live resin and sauce.
Find Full-Spectrum THC Products
Increasingly, cannabis enthusiasts are focused on the highest quality products they can get their hands on, and for many consumers, this means full-spectrum THC products. Because of this, dispensaries are prioritizing having a variety of full spectrum THC marijuana available. If you’re not seeing any in your dispensary, just talk to your budtender. They’ll either be able to guide you to what they have in stock or let you know when the products that have sold out will be back on the shelves.

THC may be the most famous cannabinoid, but did you know it doesn’t actually exist in the cannabis plant? It begins as a different cannabinoid called Tetrahydrocannabinolic Acid (THCA), which does not provide psychoactive effects. To convert THCA into THC, it must be decarboxylated by exposing it to heat or light.
THCA and THC may be closely related, but the characteristics and effects of these two cannabinoids differ greatly. In this article, we’ll explore the differences between THCA vs THC, the conversion process, potential benefits, and ways to use them.
Introduction to Cannabinoids
Cannabinoids are chemical compounds found in the cannabis plant. You have likely already heard of THC and CBD, but there are actually more than 500 known cannabinoids found in the cannabis plant!1 These compounds interact with the body’s endocannabinoid system to produce various effects. It’s essential to understand what cannabinoids are and how they may affect you, as they play a significant role in the therapeutic and recreational use of cannabis.
What is THCA?
THCA is a non-psychoactive cannabinoid found in raw cannabis–specifically in the plant’s smokable flowers. It is the precursor to THC and has a distinct chemical structure that prevents it from binding to cannabinoid receptors in the brain.2 This means trying to eat raw cannabis flower, stems, leaves, etc. will not provide intoxicating effects.
Cannabis flower with high levels of THCA is often consumed raw, typically through juicing, to take advantage of the potential health benefits without the psychoactive effects of THC.3
What is THC?
THC, formally known as Tetrahydrocannabinol, is the psychoactive compound in cannabis that produces an “intoxicating high.” In order to convert THCA into THC, it must be decarboxylated, or exposed to heat or light. This removes the carboxyl group from THCA, converting it into THC. When THC is consumed, it binds to the CB1 and CB2 receptors in your brain and body, producing its characteristic effects, known as a “high.”4
How is THCA converted to THC?
Decarboxylation is the key process that transforms THCA into THC. This chemical process, initiated by applying heat or through prolonged exposure to light, removes a carboxyl or carbon dioxide molecule group from THCA, transforming it into THC.16 Common methods of decarboxylation include smoking, vaping, baking, or using a decarbing device. This process is crucial in cannabis product manufacturing to ensure the cannabinoids are activated, and THC can produce its psychoactive effects.5
Here are the common methods of decarboxylation:
- Heat: Bake dried cannabis flower in an oven, vape or smoke cannabis, or use a specialized decarboxylation device.
- Time: Over time, THCA can slowly convert into THC at room temperature.
- Light: Exposure to UV light can also cause decarboxylation, though this method typically happens unintentionally when cannabis isn’t stored properly.
Key Differences Between THCA and THC
This topic is highly technical and can be confusing! Here’s an easier breakdown of the main differences between THC vs THCA:
Psychoactive Effects
The most significant difference between THCA vs THC flower lies in their psychoactive properties. THCA is non-intoxicating and doesn’t produce a “high” because it doesn’t bind to the brain’s cannabinoid receptors.6 In contrast, THC is psychoactive and responsible for the effects associated with cannabis use.7 Additionally, a full-spectrum THC product contains various cannabinoids, producing an entourage effect when consumed.
Medical Applications
THCA and THC may have therapeutic applications, but more studies are needed to verify the potential medical effects. THCA is believed to have anti-inflammatory, neuroprotective,8 and antiemetic properties. It may be beneficial for those who have arthritis or suffer from neurodegenerative diseases. On the other hand, THC may help relieve pain, stimulate appetite, and manage symptoms related to conditions like multiple sclerosis and cancer.9
Legal Status
The legal status of THC vs THCA differs significantly. THC is federally illegal in the United States, but it is allowed for medical or recreational use in some states.10 THCA, derived from hemp, is currently legal under the 2018 Farm Bill, provided it contains less than 0.3% THC. However, this is subject to change as regulations evolve.11
THCA in Raw Cannabis
THCA is abundant in raw cannabis, especially in the leaves and flowers. Consuming raw cannabis, such as through juicing or adding it to smoothies, may provide the benefits of the non-psychoactive cannabinoid without the intoxicating effects of THC. This method is popular among those looking to harness the potential therapeutic properties of cannabis without experiencing a “high.”12
THC in Cannabis Products
The presence of THCA vs THC in products you purchase from a dispensary vary based on the type of product you buy.
- Edibles, tinctures, or topicals typically only contain THC as the decarboxylation process occurred as the product was being manufactured.
- Disposable vapes and vape cartridges contain THCA, which is decarboxylated automatically by the battery’s heating element.
- Cannabis flower and marijuana concentrates contain THCA, and they require manual decarboxylation. Simply light the flower or concentrate in the consumption device of your choice to convert THCA to THC.
Potential Benefits of THCA
Unfortunately there isn’t enough cannabis research to be able to confirm its benefits, but there are a number of studies that may lead to further breakthroughs. When it comes to THCA, there are areas in which it could provide relief to patients:
- Neuroprotective - Support brain health and protect against neurodegenerative diseases like dementia.13
- Antiemetic - Reduce nausea and vomiting, which may be especially beneficial to chemotherapy patients.14
- Anticonvulsant - Reduce seizures in epilepsy.15
Frequently Asked Questions
Your favorite budtender is a great resource if you have questions. Here are a few of the most common we hear.
Can I consume THCA without experiencing psychoactive effects?
You can consume THCA, which is a non-psychoactive cannabinoid, without experiencing intoxication.
What’s the best way to preserve THCA in cannabis?
To preserve THCA, avoid exposing cannabis to heat or light, as these will trigger decarboxylation, the process that turns THCA into its active THC cousin.
How do THCA concentrations vary in different cannabis strains?
THCA concentrations vary similarly to THC levels. If a cannabis strain has a high THC content, it will also contain a lot of THCA.
Can I find products that contain only THCA?
Many products contain THCA only, and THCA diamonds are the most popular.
Choosing Between THCA and THC
Here’s a brief recap and summary about the differences between the two: THCA and THC are cannabinoids found in the cannabis plant. THC is psychoactive and is only activated when cannabis is decarboxylated. THCA is currently legal across the US pursuant to the 2018 Farm Bill, while THC is only legal for medical and recreational use in some states.
To choose between THCA and THC, consider your needs and preferences. If you're unsure, ask a budtender at your local dispensary for guidance.

Rick Simpson Oil, commonly known as RSO, is a marijuana concentrate known in the cannabis community for its high potency and potential therapeutic benefits. But what is Rick Simpson Oil, what is RSO used for, how is it made, and how do you use it? In this guide, we’ll dive into the history, intriguing story of its namesake, production, and more.
What is RSO?
Rick Simpson Oil (RSO) is a potent cannabis extract known for its high THC content. Unlike other cannabis concentrates, RSO, which looks like oily tar, is specifically formulated to contain a full spectrum of cannabinoids and terpenes found in the cannabis plant. The oil is often used for its potential therapeutic properties, such as pain relief and other medicinal benefits.1
The Story of Rick Simpson
It’s all in a name, right? Rick Simpson is the creator of RSO. He is a Canadian medical marijuana activist and engineer who gained fame by creating cannabis oil with a goal to treat his own health issues. Simpson’s journey with cannabis started in 1997 when he suffered a severe head injury, leading him to explore the medicinal properties of cannabis after traditional treatments failed.
In 2003, he was diagnosed with basal cell carcinoma, a type of skin cancer. Again, he turned to cannabis oil after reading a 1975 study that suggested cannabis oil may have slowed cancer growth in mice. Once in remission, Simpson believed the cannabis oil treatment cured his cancer. He has since become an advocate for the use of RSO for cancer patients, as well as for pain relief.2
Does RSO Work?
The effectiveness of RSO is a topic of much debate and ongoing research. While anecdotal evidence and some preliminary studies suggest that RSO may have the potential to treat specific medical conditions, there is no conclusive scientific evidence to fully support these claims.3
So, in short, “Does RSO work?” The answer is maybe. The THC-rich Rick Simpson Oil may improve appetite, relieve pain, and reduce nausea and vomiting in cancer patients,4 while THC and CBD, produced by the plant’s trichomes, may make cancer cells respond better to radiation.5 It may also help reduce or control epileptic seizures.6 However, more research is needed to fully understand the medical applications of cannabis.
How is Rick Simpson Oil Made?
Rick Simpson Oil is made through a highly concentrated extraction process in which high concentrations of cannabinoids–primarily THC–and terpenes are extracted from cannabis flower through the use of a solvent. The extract is refined and solvent is removed, leaving behind a thick, tar-like substance that is typically sold in a syringe.
Please note that this process should not be attempted at home as it is extremely dangerous and requires a professional-grade lab and materials.
RSO Oil vs Cannabis Oil
RSO and cannabis oil are derived from the cannabis plant, but they differ in their contents and intended use. RSO is known for its high THC content and full-spectrum cannabinoid profile, which activates the entourage effect because of how these cannabinoids and terpenes interact with the body’s endocannabinoid system. In contrast, cannabis oils are formulated to highlight specific cannabinoids, like CBD, and may not contain the full range of plant compounds found in RSO.
How Do You Use Rick Simpson Oil?
RSO, like other cannabis concentrates, can be consumed in a variety of ways.
RSO Syringe
Because RSO is so potent, accurate dosing is crucial. One of the most popular ways to purchase RSO is in a syringe, which allows the consumer to monitor even the smallest amount of the product. May patients choose RSO syringes for sublingual (under the tongue) consumption or topical applications.
RSO Edibles
RSO edibles can be purchased at a dispensary as its own product, or consumers can use an RSO syringe to add the concentrate to any food or beverage. Remember that since RSO has already been decarboxylated, it should only be added to food or drink that is ready to be consumed.
RSO Capsules
Encapsulating RSO is another convenient option, allowing you to ingest the oil in a controlled, discrete, and tasteless dose.
Vaporizing or Smoking
While not as common, RSO can be added to cannabis flower to vaporize or smoke. Remember to account for the sticky consistency when deciding how you want to consume your infused flower. We recommend a glass pipe that is easy to clean rather than attempting to make RSO-infused joints or blunts.
How Do You Dose RSO?
Dosing RSO can be challenging because of its potency. It’s recommended to start with a small amount, roughly the size of half a grain of rice, and then gradually increase the dose once you know how Rick Simpson Oil affects you. Consult with your favorite budtender or a licensed medical marijuana professional if you need dosage and other RSO advice.
Answering FAQs About Rick Simpson Oil
There is a ton of mystery around this unique concentrate, so we’ve compiled a list of the most popular questions we hear at our dispensaries.
How do you use an RSO syringe?
An RSO syringe can be used to dispense the oil sublingually or topically. It can also be added to food and drinks or put in a capsule for easy ingestion.
Can I make RSO?
No, you should not attempt to make RSO at home. The extraction process can be extremely dangerous due to the use of highly explosive solvents. Cannabis cultivators have professional equipment operated by extraction experts to ensure a safe process.
Can you smoke RSO?
Because RSO is a sticky liquid, you won’t be able to smoke it by itself. However, you can use it to infuse your cannabis flower for a more potent experience.
Can you dab RSO?
You can dab with RSO, but it’s not a common method because of its sticky consistency.
Can you cook with RSO?
Rick Simpson Oil can be added to various sweet or savory recipes to make edibles, but you should not add it until the food is completely cooked. This is because RSO has already been decarboxylated, so further exposure to heat will cause the THC to degrade.
Purchasing RSO
Rick Simpson oil has a fascinating history, and it makes sense that cannabis enthusiasts want to try RSO for recreational use. Remember that the concentrate is highly potent, so follow the newbie cannabis user’s advice of starting low and slow. Talk with your budtender if you want to know more about RSO.
