3. Double Delicious CBN RSO Oil

Double Delicious’s high-CBN RSO Oil is made with sleep in mind. It blends traditional RSO therapeutic properties with CBN, a cannabinoid known for its sedative effects.

This formulation is great for those using RSO Oil for sleep support or nighttime stress and anxiety. It delivers a heavy, full-spectrum effect that eases both the body and mind into deep relaxation, making it especially appealing if your goal is to unwind fully and settle into a calmer state before bed.

Double Delicious’ RSO Oil delivers this beneficial extract in a method that allows for flexible consumption, giving you more control over how much you take and how you build it into your nighttime routine.

4. 710 Labs RSO Full Spectrum Oil

This formulation is good if you’re using RSO Oil for deeper therapeutic support and want something that reflects the unique profile of the source flower. Because it is decarboxylated and full spectrum, it’s made for users wanting a more complete cannabis oil experience rather than a more isolated or simplified extract.

A major benefit of RSO Oil made this way is that it can deliver a fuller range of effects that feel more nuanced and plant-forward than highly refined concentrates. 710 Labs’ RSO Full Spectrum Oil offers this beneficial extract in a syringe format that supports controlled, flexible dosing.

What to Look for When Shopping for RSO Oil

When you’re looking for RSO products, you’re after the best of the best. To ensure that you get the quality you came for, there are several key things you should always look for when shopping for RSO.

• Third-Party Testing: Ensure the product has available lab results confirming potency and absence of residual solvents.
• Full-Spectrum: The oil should contain a wide range of cannabinoids and terpenes, not just THC.
• Color/Consistency: High-quality RSO is usually very thick, dark, and viscous (like molasses).
• Extraction Method: Ethanol extraction is the traditional method used to create true RSO.

Brands like RickSimpsonOil.com and Emerald Bay Extracts have easy-to-access proof of their third-party lab testing for every product they offer. RickSimpsonOil.com in particular checks every box in the list above, their products are tested thoroughly for your safety, they are full spectrum, have the right color and consistency, and are extracted by traditional means. 

Benefits & Uses of RSO Oil

Research suggests that THC and CBD, both of which occur abundantly in RSO, may have therapeutic benefits in a variety of areas:

• Cancer: Preliminary research has indicated that cannabinoids, particularly THC and CBD, may have potential anti-cancer properties, including the ability to induce apoptosis (programmed cell death) in cancer cells and inhibit tumor growth in animal models [1]. 
• Pain and Inflammation: Research suggests THC and other cannabinoids may have analgesic (pain-reducing) and anti-inflammatory properties [2,3]. Cannabinoids may work by interacting with your body’s endocannabinoid system, which regulates pain perception. 
• Neurological Conditions: Preliminary research suggests that THC, CBD, and the other cannabinoids found in RSO may have neuroprotective properties, potentially benefiting people with neurological conditions [4]. 
• Anxiety and Mood Disorders: RSO, which is high in THC and CBD, may have beneficial properties for mood disorders in lower doses (higher doses of THC may exacerbate anxiety). Preliminary research has found that THC and CBD have potential therapeutic benefits in these sorts of use cases [5,6]. 
• Appetite Stimulation: Research suggests that THC may have appetite-stimulating properties. THC has specifically been researched as an appetite stimulant in cancer patients, and many studies have shown positive results [7]. Given RSO’s high THC content, it may offer these therapeutic benefits. 
• Sleep: RSO is high in THC and CBD, which have sedative and relaxing properties, respectively. THC and CBD have both been researched for their potential therapeutic benefits for sleep disorders [8,9]. 

Conclusion: Which RSO Oil is the Best?

There are many top tier brands carrying high quality RSO oil, but from everything reviewed so far, only one is the overall best source for it: RickSimpsonOil.com. They’re the official website, have proof of third-party lab testing, and have thousands of positive reviews.

In the end, it boils down to what specific brand and products work best for your situation. You might have to explore several different brands and product types before you find the right ones.

Best RSO Oil: Frequently Asked Questions

Here are some questions our customers frequently ask us about the best RSO oil.

What Is the Best RSO Brand?

The best RSO brand depends on what you want most: potency, purity, consistency, or a specific cannabinoid profile. For people who want a classic, high-potency full-spectrum option, pure RSO oil from a trusted brand with clear product information and consistent dosing is usually the best choice.

Does RSO Get You Stoned?

Yes, RSO can absolutely get you stoned, especially if it is high in THC. Because it is a concentrated full-spectrum cannabis oil, the effects can feel much heavier and longer-lasting than what some people expect from a small amount.

How Much RSO Oil To Get High?

It usually takes only a very small amount of RSO oil to get high, especially if you are new to THC or cannabis concentrates. Most people start with a rice grain-sized amount or even less, since taking too much too fast can easily lead to a much stronger experience than intended.

Why Is RSO So Powerful?

RSO is so powerful because it is a highly concentrated cannabis extract that contains large amounts of cannabinoids along with other plant compounds. Since it is full spectrum and very dense, even a small dose can deliver strong effects that build and last for hours.

Is Anything Stronger Than RSO?

Yes, some cannabis concentrates can test higher in THC than RSO, such as distillate or certain isolate-based extracts. That said, RSO often feels stronger overall to many users because it is full spectrum, which can create a heavier, more complete effect than THC percentage alone suggests.

What Is Better Than RSO?

What is better than RSO depends on your goal. If you want a full-spectrum oil with deep, long-lasting effects, RSO is hard to beat, but if you want something cleaner-tasting, easier to dose, or less intense, products like gummies, tinctures, or distillates may be a better fit.

How Strong Is One Gram Of RSO?

One gram of RSO is very strong and usually contains several hundred milligrams of THC, often enough for many doses rather than one. The exact strength depends on the formula, but for most people, 1 gram is far more than a single serving.

Does RSO Hit Harder Than Edibles?

RSO can hit harder than standard edibles because it is more concentrated and often contains a fuller range of cannabis compounds. Even when the THC amount looks similar on paper, RSO may feel heavier, stronger, and longer-lasting because of its full-spectrum profile.
