There’s a quiet ritual happening in kitchens across Capitol Hill and Petworth β€” DC patients carefully reducing solvent from jars of dark, potent rick simpson oil they’ve made from flower they chose themselves, and the strain they started with made all the difference.

If you’ve spent any time researching full spectrum extracts, you’ve probably come across rick simpson oil β€” the thick, tar-like concentrate that’s become a cornerstone of many medical cannabis patients’ routines. RSO oil isn’t your typical dab or vape cartridge. It’s designed to preserve the entire chemical profile of the plant: cannabinoids, terpenes, flavonoids, all of it. And because the process is relatively straightforward (though not without safety considerations), a growing number of DC cannabis patients are making it at home. But here’s the thing nobody tells you upfront: the strain you start with basically determines everything about your finished product.

We see this play out constantly at Green Legacy. Someone walks in wanting to make RSO for the first time, and their very first question is usually about the extraction process β€” not the starting material. We get it, the chemistry part feels like the main event. But after six years of helping DC medical cannabis patients dial in their approach, we can tell you that strain selection is where the real magic happens. Browse our tested flower options and you’ll see exactly why we obsess over terpene profiles and cannabinoid ratios before anything hits a jar.

I remember a patient from Adams Morgan β€” let’s call her Diane β€” who made her first batch of RSO from a random sativa she grabbed without much thought. The result? Racy, anxious, and honestly kind of unpleasant for her particular needs (she was managing chronic pain and insomnia). Second attempt, we helped her pick a heavy indica with solid myrcene numbers and over 25% THC. Night and day difference. She literally texted us a photo of her sleeping dog with the caption “me after batch #2.” That’s the kind of outcome we’re chasing here.

5 Essential Tips for Better Rick Simpson Oil

01
🌿

Prioritize THC-Heavy Indicas First

Traditional rick simpson oil calls for high-THC indica strains, and there’s a good reason for that. Indicas tend to deliver the sedative, full-body effects most RSO patients are after β€” especially for pain, sleep, and appetite. Look for strains testing above 22% THC with dominant myrcene or linalool terpenes.

02
πŸ’¨

Check Terpene Profiles, Not Just THC

THC percentage gets all the hype, but terpenes are doing serious heavy lifting in any full spectrum extract. A strain with 20% THC and rich terpene diversity can outperform a 28% THC strain with a flat profile. Ask your budtender for COA data β€” those numbers don’t lie.

03
πŸ§ͺ

Always Demand Lab-Tested Flower

You’re going to be concentrating everything in that plant material β€” including any contaminants. If there are pesticides, heavy metals, or mold in your starting flower, they’ll be concentrated in your RSO oil too. Only use flower from a DC medical cannabis program licensed dispensary with verified lab results.

04
πŸŒ™

Consider CBD-Blended Strains for Balance

Not everyone needs a THC sledgehammer. Patients managing inflammation or anxiety often do better with a 1:1 or 2:1 THC-to-CBD ratio in their RSO. These balanced strains produce a gentler extract that’s easier to dose and still incredibly effective for daytime symptom management.

05
πŸ“‹

Freshness and Cure Matter Enormously

Old, dry, crumbly flower produces mediocre RSO β€” period. You want properly cured bud that still has some give when you squeeze it and smells loud when you crack the jar. Degraded terpenes and oxidized cannabinoids mean a less potent, less flavorful final product. Buy fresh, process quickly.

Your Burning Questions About Rick Simpson Oil, Answered

What exactly is rick simpson oil and how is it different from other concentrates?

Rick simpson oil is a full spectrum extract made by soaking cannabis flower in a solvent (traditionally ethanol or isopropyl alcohol), then evaporating the solvent to leave behind a thick, dark oil. Unlike distillate or isolate, RSO oil retains the plant’s entire chemical profile β€” cannabinoids, terpenes, flavonoids, everything. That’s why patients often report stronger therapeutic effects compared to more refined concentrates. You can learn more about extract types on Leafly’s extract guide.

Can I legally make RSO at home as a DC medical cannabis patient?

DC’s medical cannabis regulations are managed by ABCA and DC Health. As a registered patient, you can possess and use medical cannabis products, but home extraction involves flammable solvents, which carries both legal and safety considerations. We strongly recommend reviewing the latest DC Health medical cannabis program guidelines and consulting with your certifying provider before attempting any home extraction.

How much flower do I need to make a batch of RSO?

The traditional Rick Simpson method calls for roughly one ounce of quality flower to produce about 3–4 grams of finished oil. Yields vary depending on the strain’s resin content and your technique. Starting with high-quality, properly cured flower from a licensed dispensary will always give you the best return β€” garbage in, garbage out applies big time here.

What’s the best way to dose RSO oil if I’m new to it?

Start absurdly small β€” we’re talking a grain-of-rice-sized dose. RSO is incredibly concentrated, often hitting 60–90% total cannabinoids. Most patients place it on a small piece of food or under the tongue. Wait at least two hours before considering another dose. It’s similar to dosing edibles in that the effects take time to build and can be intense if you overshoot.

Does it matter whether I use indica or sativa strains for rick simpson oil?

Absolutely. Your strain choice directly shapes the effect profile of your finished oil. Indicas tend to produce RSO that’s more sedating and body-focused (ideal for pain and sleep), while sativas can yield an oil that’s more cerebral and energizing β€” which isn’t always what RSO patients want. Most experienced patients we work with in Dupont Circle and across DC lean toward heavy indicas or balanced hybrids for their batches.
