If you’ve explored medical marijuana treatment options in West Virginia, you may have come across something called RSO. But what is RSO, and why are patients turning to it for relief?
RSO stands for Rick Simpson Oil, a highly concentrated marijuana extract known for its strong potency and full-spectrum benefits. Originally developed by a Canadian engineer named Rick Simpson, this oil gained attention after Simpson used it to help his skin cancer symptoms. Since then, RSO has been widely explored for its potential therapeutic properties, especially among medical marijuana patients dealing with chronic conditions, including those in West Virginia.
How Is RSO Made?
RSO is made using a method that extracts all the beneficial compounds from the marijuana plant, including THC, CBD, terpenes, and flavonoids. This full-spectrum approach ensures that patients receive the complete range of potential therapeutic effects from the plant.
Traditionally, RSO is produced by soaking marijuana in a solvent, then filtering and boiling the mixture down to leave behind a thick, sticky oil. The result is a powerful extract that can contain very high levels of THC, often exceeding 60–90%.
Because of its strength, RSO is typically used in very small doses. Patients often start with a drop the size of a grain of rice and gradually increase based on their body’s response.
What Do Patients Use RSO For?
So, what is RSO used for? In West Virginia and other states where medical marijuana is legal, RSO is most commonly used by patients managing serious or chronic health conditions. These may include:
Some patients also report benefits for anxiety, depression, and appetite stimulation. Due to its high potency, RSO is typically reserved for those with a high tolerance or specific therapeutic needs that require strong, sustained symptom relief.
It can be taken orally, applied topically for skin-related concerns, or used in capsule form for more controlled dosing. Because of its strong THC content, RSO can produce significant psychoactive effects, so it's important to consult with a qualified medical professional before starting treatment.
RSO in West Virginia Dispensaries
As of 2025, medical marijuana patients in West Virginia have access to a variety of products, including RSO. Licensed dispensaries throughout the state offer this product, often labeled as full-extract marijuana oil (FECO). Patients are encouraged to speak with dispensary staff about proper usage and dosing.
RSO is typically available in oral syringes for precise dosing and may come in different formulations or strain types depending on the dispensary. Patients looking for RSO can visit their local dispensary and ask specifically for full-extract oil options or products designed for chronic symptom relief.
Inventory may vary by location, so checking with dispensaries ahead of time or browsing their product menus online can help ensure availability.
