Gibson Pharmacy – Complete Guide to Rick Simpson Oil Near Me (RSO) for Therapeutic Use

Gibson Pharmacy is a fully licensed, legal pharmacy operating in compliance with FDA, DEA, and state board of pharmacy regulations. Rick Simpson Oil (RSO) is a full-extract cannabis oil that is NOT FDA-approved for the treatment of any medical condition . This guide is for informational and educational purposes. 

The information in this leaflet is based on available clinical literature, state regulations, and patient experience reports. Always consult your physician before using any cannabis-derived product. Rick Simpson Oil near me searches should only be conducted in jurisdictions where cannabis is legal, and purchases should only be made from licensed dispensaries.

What Is Rick Simpson Oil RSO?

Rso Rick Simpson oil is a concentrated full-extract cannabis oil named after Rick Simpson, a Canadian medical cannabis activist who developed the extraction method in 2003 after reportedly treating his own basal cell carcinoma with homemade cannabis oil .

RSO is a full-spectrum extract that retains the complete profile of cannabinoids (THC, CBD, CBG, CBN), terpenes, flavonoids, and other plant compounds from the cannabis plant . Unlike distillates or isolates that isolate a single molecule, RSO keeps all components together to produce the entourage effect—the theory that cannabinoids work better in concert than alone .

Feature	Rick Simpson Oil (RSO)
Active compounds	Full-spectrum cannabinoids (THC-dominant, 50-90% THC)
THC concentration	Typically 500-900mg per 1-gram syringe (50-90%)
CBD concentration	Low (often <1-5%)
Appearance	Dark brown to black, thick, tar-like, sticky consistency
Typical packaging	1-gram oral syringe with plunger for controlled dispensing
Legal status	Varies by jurisdiction; available only in licensed dispensaries in legal states
FDA approval	NOT FDA-approved for any medical condition
Primary route of administration	Oral (swallowed) or sublingual

RSO vs. CBD Oil

A common point of confusion is that RSO is often mistaken for CBD oil. RSO is not the same as CBD oil . Key differences:

• CBD oil is usually low or free of THC and non-psychoactive

• RSO is THC-dominant (50-90%) and highly psychoactive 

• RSO is far more potent per volume than any edible, tincture, or capsule 

RSO vs. FECO (Full Extract Cannabis Oil)

RSO and FECO (Full Extract Cannabis Oil) are essentially the same product—a highly concentrated, full-spectrum cannabis extract typically dispensed in a 1-gram oral syringe . Both terms are often used interchangeably.

Uses of Rick Simpson Oil

Reported Uses

Patients in legal medical cannabis programs use RSO for symptom management, not as a cure. According to patient reports and clinical observations, potential uses include :

Symptom Area	Reported Benefit
Cancer-related symptoms	Pain relief, nausea control (chemotherapy-induced), appetite stimulation
Chronic pain	Neuropathic pain, inflammatory pain
Insomnia	Sleep induction and maintenance
Inflammation	Reduction of inflammatory markers
Anxiety/mood	Mood enhancement (at appropriate doses; higher doses may worsen anxiety)
Hot flashes (menopausal)	Symptom relief in some women

What RSO Is NOT

To avoid confusion and unrealistic expectations, it is critically important to understand :

• RSO is NOT a proven cure for cancer 

• There are NO robust human clinical trials proving RSO treats any cancer 

• RSO is NOT FDA-approved for the treatment of any medical condition 

• RSO is NOT risk-free, even though it is plant-based

• RSO should NOT replace medical treatment prescribed by a qualified professional 

While laboratory and animal studies suggest certain cannabinoids can trigger cancer cell death (apoptosis), slow tumor growth, and block signals that drive cancer spread, there are no large human clinical trials of RSO for any cancer type . Using RSO without medical guidance—especially for serious or life-threatening conditions—can delay effective care .

• No robust human clinical trials prove RSO cures or treats cancer 

• Most positive data come from cell cultures or animal models, not human studies 

• Anecdotal reports of cancer remission cannot be isolated from other treatments or confounding factors 

• The “Rick Simpson Protocol” recommending 1 gram per day (500-900mg THC daily) is NOT medically validated and poses significant overconsumption risk

Dosage: Comprehensive Guide

Critical Safety Information

RSO is 50-90% THC. A full 1g syringe contains 500-900mg THC. For context, a beginner edible dose is 2.5-5mg THC . RSO is dramatically more concentrated than any other oral cannabis product. The margin between an effective dose and an uncomfortable dose is very small.

The “Rice Grain” Rule

The universally recommended starting dose for RSO is one-half to one grain of rice (approximately 5-10mg THC) . This applies regardless of prior cannabis experience.

Dose Level	Amount	Approximate THC Content	Typical Effect
Beginner (Start Here)	½ – 1 grain of rice	5-10mg	Mild symptom relief, minimal psychoactivity
Low	1-2 grains of rice	10-20mg	Noticeable symptom relief, mild psychoactive effects
Moderate	3-5 grains of rice	30-50mg	Significant symptom relief, moderate psychoactive effects
High	½ syringe (0.5g)	250-450mg	Strong psychoactive effects, only for tolerant patients
Extreme (Not Recommended)	1 full syringe (1g)	500-900mg	Intense effects; NOT medically validated

The “Rick Simpson Protocol” – 

The online “Rick Simpson Protocol” recommends gradually increasing to 1 gram of RSO per day (500-900mg THC daily) over 90 days . This protocol is NOT medically validated and is NOT recommended without physician supervision . While some patients under medical supervision do use high-dose RSO regimens, the protocol as popularized online lacks clinical evidence and poses significant overconsumption risk .

Standard Dosing Approach (Harm Reduction)

Phase 1: Initial Test Dose

• Start with ½ grain of rice (approximately 5mg THC)

• Administer with food

• Wait at least 2-4 hours before considering additional dose

• Observe effects (onset 30-120 minutes, duration 4-8+ hours)

Phase 2: Gradual Increase

• If no desired effect and no significant side effects, increase by ½ grain of rice every 3-4 days

• Do not rush. Listen to your body 

• Keep a detailed dosing journal: date, time, amount, route, onset time, effects, and duration 

Phase 3: Maintenance

• Most patients find their maintenance dose well below the aggressive “Rick Simpson Protocol” 

• Maintenance doses are highly individual and always should be physician-guided

Dose Adjustment Tips

• If psychoactive effects are too strong: decrease dose

• If no symptom relief: increase dose slowly

• If side effects (anxiety, nausea) occur: decrease dose

• Always allow 2-4 hours between doses when swallowed (oral ingestion has slow onset)

What to Know Before Taking RSO

Medical Conditions to Disclose to Your Doctor

Before using RSO, inform your healthcare provider if you have :

• Cancer (any type) – discuss with your oncologist before using

• Heart disease, arrhythmias, or hypertension

• Liver disease (cirrhosis, hepatitis, fatty liver)

• Kidney disease

• Seizure disorder

• Psychiatric conditions (psychosis, schizophrenia, bipolar disorder, severe anxiety)

• History of substance use disorder

• Pregnancy or breastfeeding

Critical: Do NOT Replace Medical Treatment

Never replace proven cancer treatments (surgery, radiation, chemotherapy, immunotherapy) with RSO . RSO is NOT a substitute for conventional medical care. Discuss any use of cannabis products with your oncologist before adding them to your regimen .

Drug Interactions

RSO has the potential to interact with many medications :

Medication Class	Potential Interaction
Chemotherapy agents	Possible interactions via CYP450 enzymes
Antidepressants (SSRIs, SNRIs)	May increase or decrease effects
Benzodiazepines (Xanax, Valium, Ativan)	Additive sedation, respiratory depression risk
Sleep aids (Ambien, Lunesta)	Additive sedation
Anticoagulants (warfarin, apixaban, rivaroxaban)	Increased bleeding risk
Blood pressure medications	Possible blood pressure changes
CYP450 substrates (many medications)	THC and CBD inhibit liver enzymes

Pregnancy and Breastfeeding

RSO is not recommended during pregnancy, while trying to conceive, or while breastfeeding due to potential risks to the baby .

Time and Instructions of Consumption

Onset and Duration

Route	Onset Time	Duration
Oral (swallowed)	30-120 minutes	4-8+ hours
Sublingual (under tongue)	15-45 minutes	4-8+ hours (initial faster onset)

Oral (Swallowed) Method – Most Common

Step‑by‑step instructions :

1. Warm the syringe between your hands for 20-30 seconds. RSO is very thick at room temperature and flows more easily when slightly warmed.

2. Dispense a rice-grain-sized amount (approximately 5-10mg THC for beginners) onto a small piece of food: cracker, bread, banana slice, or peanut butter ball. The food serves two purposes: masks the strong, bitter taste, and fat content improves cannabinoid absorption.

3. Swallow the food with the RSO. Do not chew or try to taste the oil.

4. Wait 30-120 minutes for onset.

5. Expect duration of 4-8+ hours.

When swallowed, RSO is processed through the digestive system and metabolized by the liver, converting THC to 11‑hydroxy‑THC, which crosses the blood-brain barrier more readily and produces stronger, longer‑lasting psychoactive effects than inhaled THC .

Sublingual Method

1. Dispense a small amount directly under the tongue or along the gum line

2. Hold for 60-90 seconds to allow absorption through the mucous membranes before swallowing

3. Provides faster onset (15-45 minutes) with a secondary wave of effects when the swallowed portion is processed orally 

Capsule Method (Tasteless, Precise)

Load RSO into empty gel capsules (available at any pharmacy) for consistent, pre-portioned, tasteless oral dosing .

Topical Application

Applied to the skin for localized pain (less psychoactive effect as minimal absorption through intact skin) .

Allergies, Conditions, or Health Issues

Allergic Reactions (Seek Emergency Care)

Allergic reactions to cannabis are rare but possible:

• Rash, hives, or itching

• Swelling of the face, lips, tongue, or throat (angioedema)

• Difficulty breathing or wheezing

• Anaphylaxis (extremely rare)

Special Populations

Population	Consideration
Elderly patients	Higher sensitivity to psychoactive effects; start at lower dose (¼ grain of rice)
Patients with liver disease	Use extreme caution; RSO may stress the liver
Patients with cardiovascular disease	THC can increase heart rate and blood pressure
Patients with psychiatric conditions	THC may worsen psychosis, mania, or anxiety
Pregnant or breastfeeding women	Not recommended
Patients on multiple medications	High risk of drug interactions; require physician review

Food, Drinks, and Activities to Avoid

Substance/Activity	Interaction	Recommendation
Alcohol	Additive sedation, dizziness, impaired coordination	Avoid combining; both substances intensify each other’s effects
Benzodiazepines	Additive sedation, risk of excessive drowsiness	Avoid combining without medical supervision
Other CNS depressants	Additive sedation, respiratory depression risk	Use extreme caution
Grapefruit juice	May alter CYP450 metabolism	No specific restriction, but caution advised
High-fat meals	May enhance absorption (can be used intentionally for stronger effects)	No restriction; fat improves absorption

Activities to Avoid

• Driving or operating heavy machinery for at least 6-8 hours after taking RSO 

• Operating dangerous equipment while under the influence

• Pregnancy – avoid completely

• Breastfeeding – avoid completely
