Rick Simpson Oil Side Effects: What to Expect and How to Manage
Rick Simpson oil side effects can include drowsiness, dry mouth, red eyes, dizziness, increased heart rate, and temporary memory issues. Most are manageable by starting with a low dose and increasing gradually.
RSO Benefits: How It Works for Pain, Sleep, and More
Rick Simpson oil (RSO) is a full-extract cannabis oil rich in THC, CBD, and CBG. It works by interacting with your endocannabinoid system, which helps regulate pain, sleep, mood, and appetite. Many people use RSO for chronic pain, cancer-related symptoms, and sleep issues.
| Condition | How RSO Helps | What Users Report |
|---|---|---|
| Chronic pain | THC and CBD bind to CB1 and CB2 receptors, reducing inflammation and pain signaling. | Many find relief from neuropathic and inflammatory pain. |
| Sleep | THC promotes drowsiness and helps with falling asleep and staying asleep. | Users often report deeper, more restful sleep. |
| Cancer-related symptoms | THC may reduce nausea, stimulate appetite, and improve quality of life. | Some patients use it alongside conventional treatments (always consult your oncologist). |
| Anxiety | Low doses of THC can ease anxiety, though high doses may worsen it. | Start low and adjust to find your optimal dose. |
| Inflammation | CBD and CBG have anti-inflammatory properties. | May help with autoimmune conditions and joint pain. |
RSO is not a cure-all, but its entourage effect—where THC, CBD, and other cannabinoids work together—enhances therapeutic benefits. For a deeper look at what RSO is and how to use it, see our RSO oil guide.
Can You Smoke RSO? Risks and Recommendations
No, you should not smoke or dab RSO. RSO is a thick, sticky oil meant for oral or sublingual use. Smoking it can damage your lungs and may not deliver the intended therapeutic dose.
A good fit if…
- You want the full entourage effect and precise dosing.
- You prefer a method that avoids inhalation risks.
- You need long-lasting relief (oral ingestion lasts longer than inhalation).
Consider another option if…
- You need immediate onset (sublingual tincture or nasal spray may be better).
- You dislike the taste of oil (try capsules or edibles).

Safe RSO Dosing: Start Low, Go Slow
To minimize side effects, start with a dose about the size of a grain of rice (roughly 10–20 mg of THC) and increase gradually every few days. This approach lets your body adjust and helps you find your optimal dose.
| Week | Dose | Frequency |
|---|---|---|
| 1 | Rice grain (10–20 mg) | Twice daily |
| 2 | Increase by 10–20 mg | Twice daily |
| 3 | Continue increasing as tolerated | Twice daily |
| 4+ | Maintain or adjust based on effects | As needed |
Always wait at least 2 hours before taking more, as effects can take time to appear. For a precise calculator, see our RSO dosage calculator.
Rick Simpson Oil Side Effects: What to Expect
Common side effects include drowsiness, dry mouth, red eyes, dizziness, increased heart rate, and temporary memory issues. These are usually mild and subside as your body adjusts.
| Side Effect | Why It Happens | How to Manage |
|---|---|---|
| Drowsiness | THC has sedative effects, especially at higher doses. | Take RSO in the evening or reduce your dose. |
| Dry mouth | Cannabinoids reduce saliva production. | Stay hydrated and chew gum. |
| Red eyes | THC lowers blood pressure, causing blood vessels in the eyes to dilate. | Use eye drops; it's temporary. |
| Dizziness | Blood pressure changes can cause lightheadedness. | Sit or lie down until it passes. |
| Increased heart rate | THC can temporarily raise heart rate. | Avoid if you have heart conditions; consult your doctor. |
| Memory issues | THC affects short-term memory. | Use lower doses and avoid driving. |
If side effects are severe or persistent, stop use and consult a healthcare provider.
Tetrahydrocannabinol
Tetrahydrocannabinol, commonly known as THC, is the main psychoactive compound in cannabis. It binds to cannabinoid receptors in the brain and body, producing effects like euphoria, relaxation, and altered perception. THC also has therapeutic uses, such as reducing nausea and stimulating appetite in cancer patients. It can be taken orally, inhaled, or applied topically, with onset and duration varying by method. Side effects may include dry mouth, red eyes, drowsiness, and anxiety, especially at high doses. Understanding how THC works helps you anticipate and manage the side effects of Rick Simpson oil, ensuring a safer and more effective experience.
RSO Onset and Duration: How Long Do Effects Last?
When taken sublingually, RSO effects typically begin within 30–90 minutes and peak around 2–3 hours. If swallowed, onset may take 1–2 hours. Effects generally last 4–6 hours, but can persist longer with higher doses.
| Method | Onset | Duration |
|---|---|---|
| Sublingual (under tongue) | 30–90 minutes | 4–6 hours |
| Oral (swallowed) | 1–2 hours | 6–8 hours |
| Nasal spray | 15–30 minutes | 3–4 hours |
Start with a low dose and wait at least 2 hours before taking more to avoid overmedicating.
What Does an RSO High Feel Like?
An RSO high is often described as a deep, full-body relaxation with a strong sense of calm. Because RSO is a full-extract oil, the high can be more intense than smoking flower, especially at higher doses. Some people feel euphoric and talkative, while others may feel sleepy or introspective.
For beginners, the high can be overwhelming, leading to anxiety or paranoia. That's why starting low and going slow is crucial. If you feel too high, try to relax, drink water, and remember the effects will pass.
Who Should Avoid RSO?
RSO is not for everyone. Certain groups should avoid it or use it only under medical supervision.
- Pregnant or breastfeeding women – THC can affect fetal development and pass into breast milk.
- People with heart conditions – THC can increase heart rate and blood pressure.
- Those with a history of psychosis or schizophrenia – THC may worsen symptoms.
- People taking sedatives or antidepressants – RSO can interact and amplify effects.
- Anyone allergic to cannabis – Rare but possible.
Always consult your doctor before starting RSO, especially if you have underlying health conditions.
Where to Buy RSO and Legal Status
