"What's the difference between RSO tablets, RSO pills, and RSO capsules, and how do I take them?" If you've seen all three terms on a dispensary menu, you're not alone in wondering. They describe slightly different products that share one idea: a measured dose of full-spectrum cannabis oil you swallow, instead of oil you have to squeeze out of a syringe.
RSO tablets, pills, and capsules are oral doses of Rick Simpson Oil, a concentrated full-spectrum cannabis extract. Tablets and pills are usually solid and can often be split; capsules hold the oil inside a shell and can't. All of them work like an edible: effects typically begin 30 minutes to 2 hours after you swallow, peak around 1.5 to 3 hours, and can last 6 to 8 hours. Start with a small dose and wait at least 2 hours before taking more.
The details matter more than the names, though. What's inside the tablet, how strong it is, whether you can split it, and how you take it with food all shape what you'll feel. Here's how to think about each.
What are RSO tablets and RSO capsules?
RSO (Rick Simpson Oil) is a whole-plant cannabis extract. Rather than refining cannabis down to a single compound, it keeps THC or CBD alongside minor cannabinoids, terpenes, and other plant compounds. In its raw form it's thick and dark, with a tar-like texture, which is why it has traditionally been sold in syringes.
Tablets and capsules package that oil into a pre-measured dose:
RSO tablets (or pills) are solid doses. Formulations differ by brand: some press RSO into a powder base, others combine it with an oil. Many are scored so they can be broken in half or quarters.
RSO capsules hold RSO, usually mixed with a carrier oil, inside a hard or soft gel shell. They're easy to swallow but can't be split, so the dose is fixed.
Both are taken by mouth and absorbed through the digestive system, so their timing and duration are very similar. The practical difference is flexibility: a scored tablet lets you take a half or a quarter, which helps if you're new or still finding your dose.
What's inside an Emerald Bay RSO tablet?
Ingredient lists are the clearest way to compare products, so here is ours plainly. Emerald Bay RSO tablets contain three ingredients: full-spectrum, strain-specific RSO, microcrystalline cellulose (a plant-fiber base), and silicon dioxide. There's no sugar, no flavoring, and no added terpenes. Every batch is triple lab-tested, and the tablets are scored for splitting. They come in strengths from 10mg to 100mg, with 25mg, 50mg, and 100mg as the core line, across indica, sativa, hybrid, CBD, and CBG strains.
One practical point about timing: cannabinoids dissolve in fat, and fat appears to help the body absorb them. Animal research found that co-administering cannabinoids with dietary lipids increased systemic exposure to THC and CBD, and a human study of oral CBD found substantially higher blood levels after a high-fat meal than in a fasted state. Those studies weren't done on RSO tablets specifically, but they suggest that taking a tablet with a meal that contains some fat may change how much you absorb, so try to take it the same way each time.
25mg vs. 50mg vs. 100mg: which RSO tablet strength fits?
There's no universally right strength, and this isn't individual dosing advice. These are the general patterns we hear about from budtenders and customers, set against what the clinical literature says about starting doses.
Starting points. Clinical guidance tends to begin lower than most people expect. A 2021 international consensus on medical cannabis dosing suggested that people new to THC start around 1 to 2.5mg, and a review of cannabis administration and dosing recommends increasing slowly. A quarter of a 10mg or 25mg tablet sits close to that range.
25mg tablets are the most flexible. Split into quarters, each piece is a little over 6mg; halves are 12.5mg. Many people use this strength to learn their response.
50mg tablets tend to suit people who already know they need more than a beginner dose, often for evening use.
100mg tablets are intended for experienced, high-tolerance users. For someone new to THC, a 100mg tablet is not a starting point, even split.
Strain matters as well as milligrams. CBD- and CBG-dominant tablets are far less intoxicating than THC-dominant ones at the same weight, and indica and sativa strains are chosen for different times of day. Our step-by-step RSO tablet guide goes deeper into splitting and timing.
How to take RSO tablets and capsules
Split if you need to. Press firmly along the score line with clean, dry fingers, or use an inexpensive pill splitter for cleaner quarters.
Swallow with water, or chew. Either works. Chewing doesn't make a tablet work dramatically faster, because absorption still happens mostly in the digestive tract.
Be consistent about food. Taking a dose with a meal that contains some fat may increase absorption and delay the onset a little. Taking it on an empty stomach may feel quicker but less predictable. Either can work; the key is to be consistent so you can compare one day to the next.
Time it. If the goal is sleep, many people take their dose 1 to 2 hours before bed. For daytime use, a CBD-, CBG-, or sativa-forward tablet at a lower dose is the more common approach.
Wait 2 hours before redosing. This is the most important rule with any oral cannabis.
How long do RSO capsules and tablets take to kick in?
Oral cannabis is slow and variable, and that's simply how the body handles it. A review of human cannabinoid pharmacokinetics describes oral THC bioavailability in the single digits to low teens (percent) with delayed and irregular peaks, and a controlled study of oral cannabis found drug effects that persisted for several hours.
Here's what's happening. Swallowed THC travels from the gut to the liver before reaching the rest of the body. The liver converts part of it into 11-hydroxy-THC, an active metabolite that contributes to the longer, more body-centered feel of edibles. Your stomach contents, metabolism, and liver enzymes all shift the timing, which is why the same tablet can feel different on different days. We explain this in more detail in how long RSO takes to kick in.
In practical terms: expect onset in 30 minutes to 2 hours, a peak around 1.5 to 3 hours, and 6 to 8 hours of effect, sometimes longer at higher doses.
RSO tablets vs. regular edibles and gummies
Are RSO edibles stronger? Milligram for milligram, not necessarily. A 10mg RSO tablet and a 10mg gummy contain the same labeled amount of THC. What differs is what comes along with it. Many gummies are made with distillate, a refined extract that is mostly THC, plus sugar, flavoring, and gelatin or pectin. RSO tablets keep the broader set of plant compounds. Whether those extra compounds change the experience in a meaningful way is still debated in the research; the "entourage effect" is plausible but not yet well established in human trials.
Many people do notice that RSO products feel "heavier" or longer-lasting. Some of that may be dose (RSO tablets often come in higher strengths than the typical 5 or 10mg gummy) and some may be the oral route itself.
Sugar and additives. For people managing blood sugar or avoiding sweeteners, a tablet with no sugar is a practical advantage. We wrote about this in why our products are sugar-free.
Do RSO capsules get you high? If they contain THC, yes. CBD- and CBG-dominant products produce little or no high at typical doses, though CBD-dominant products often contain some THC. Check the label and lab results for the ratio.
The bottom line
The real advantage of an RSO tablet isn't convenience for its own sake. It's that you can take a known, repeatable amount of full-spectrum oil and adjust it in small, predictable steps. That matters more than the name on the menu. You can find Emerald Bay RSO tablets at licensed California dispensaries; our store locator lists retailers near you.
Frequently asked questions
What are RSO capsules?
RSO capsules are hard or soft gel capsules filled with Rick Simpson Oil, usually blended with a carrier oil. They deliver a fixed oral dose and work like an edible. Unlike scored tablets, capsules can't be split, so they're less flexible for small doses.
How long do RSO capsules take to kick in?
Typically 30 minutes to 2 hours, with peak effects around 1.5 to 3 hours after swallowing. Food, metabolism, and dose all change the timing. Wait at least 2 hours before deciding to take more.
Can you split an RSO tablet?
If it's scored, yes. Emerald Bay tablets are scored for halves and quarters, which makes it easier to start low and adjust gradually.
Are RSO pills stronger than edibles?
Not by milligram. A 10mg RSO pill and a 10mg gummy contain the same labeled THC. RSO pills contain more of the plant's other compounds and are often sold in higher strengths, which is why many people experience them as stronger.
This article is educational and doesn't provide medical or dosing advice. Responses to oral cannabis vary widely, and taking too much is the most common problem: an emergency department study found edibles were linked to more cannabis-related visits than their share of sales would predict. Cannabis is for adults 21+, laws differ by location, and cannabinoids can interact with other medications. Store tablets in child-resistant packaging, away from children and pets. If you're pregnant, nursing, or managing a medical condition, talk with a healthcare provider who knows your full history.
