What Is RSO?

Rick Simpson Oil, or RSO, is a thick, full-spectrum cannabis oil originally popularized by Rick Simpson after he began sharing his high-THC oil preparation with people seeking stronger plant-based support. 

True RSO is not regular CBD oil or distillate. It’s a concentrated cannabis extract that contains THC, other cannabinoids, terpenes, flavonoids, chlorophyll, lipids, and other native plant compounds.

Because RSO is usually high in THC, it can feel much stronger than typical edibles or tinctures. Many users take it orally, place it under the tongue, add it to food, or use it topically depending on their needs.

Uses & Benefits

You may be looking for RSO because you want a stronger, longer-lasting cannabis product than flower, vapes, or standard edibles. 

Our RSO products are commonly used by therapeutic users who want full-spectrum effects, precise dosing, and a high-THC cannabis oil experience in a discreet format.

Types Of RSO

RSO extract can be made from indica, sativa, or hybrid cannabis strains. 

  • Indica RSO is often chosen for nighttime use, body-heavy effects, and deeper relaxation. 
  • Sativa RSO may feel more uplifting or mentally active. 
  • Hybrid RSO gives you a more balanced middle ground, depending on the strain and cannabinoid profile.

Is RSO Legal In California?

Yes, RSO is legal in California for both medical and adult-use cannabis consumers. California allows adults 21 and older to buy cannabis, while medical patients 18 and older can buy cannabis with a physician’s recommendation. 

The California Department of Cannabis Control states that cannabis is legal in the state for medicinal and adult use, though cities and counties can set stricter local rules.

If you’re buying cannabis recreationally, California law allows possession of up to 28.5 grams of cannabis and up to 8 grams of concentrated cannabis. 

In California, you can legally buy RSO as a concentrate, but adult-use buyers are capped at 8g of cannabis concentrate per day. However, when you’re buying RSO protocols that you need to stock up on (typically for medical purposes), you may run into purchasing issues due to the 8g daily limit.

Ordering from RickSimpsonOil.com is legal for California customers because California has a legal medical cannabis market and permits high-THC cannabis products through licensed channels.

Where To Buy RSO In California

If you’re searching for real Rick Simpson Oil in California, you have several local options to explore. California dispensary menus frequently change by city, brand, and batch, so check live inventory before driving across Los Angeles, San Diego, the Bay Area, Sacramento, or Orange County.

Here’s where to check:

  • Mankind Dispensary, San Diego: Mankind has listed Jetty Extracts Rick Simpson Oil in a 0.5g format with high THC potency, making it a relevant San Diego option for shoppers looking for RSO-style cannabis oil.
  • Natural Healing Center, Grover Beach: NHC has listed Emerald Bay Extracts Rick Simpson Oil Syringe products, including 1g RSO options, which makes it a Central Coast option for RSO shoppers.
  • Med Leaf Dispensary: Med Leaf has listed 1g RSO oil syringes described as full-extract cannabis oil meant to be taken orally, with THC potency shown on the menu.
  • The Artist Tree, Laguna Woods: The Artist Tree has listed Rick Simpson Oil syringe options on its Laguna Woods menu, giving Orange County shoppers another local path to RSO-style products.
  • SPARC, San Francisco, Santa Rosa, Sebastopol, Sonoma, And Napa: SPARC operates across major Northern California cannabis markets and carries a broad dispensary product selection, making it worth checking for RSO or full-spectrum oil availability.

Inventory can change frequently, so it’s always smart to check the store’s live menu or call ahead to confirm they currently stock RSO, FSO, or similar concentrated cannabis oil products.
