How to Make and Dose Cannabis Capsules Correctly
Oral administration via encapsulated oil offers a method for precise, repeatable dosing. When ingested, cannabinoids bypass the lungs and move through the digestive system to the liver. Here, Delta-9-THC undergoes first-pass metabolism, converting into 11-hydroxy-THC. This metabolite may stay in the system longer than inhaled cannabis, potentially providing a sustained therapeutic window.

The Role of Lipid-Based Encapsulation
Cannabinoids are lipophilic. By using a lipid carrier like MCT or coconut oil, you may improve bioavailability, supporting the transport of the compound into systemic circulation. Capsules also address the practical challenges of cannabis use, effectively neutralizing the flavors and odors associated with raw plant matter and volatile terpenes.
Technical Requirements for Preparation
Precision is essential. To achieve consistent dosing, use the following hardware and media:
- Lipid Carriers: MCT oil is effective because it remains liquid at room temperature. Coconut oil is a reliable alternative, though it transitions to a solid state at temperatures below 76°F (24°C).
- Capsule Sizing: Size 00 shells hold approximately 0.7 ml of liquid. Size 0 shells hold roughly 0.5 ml.
- Precision Tools: Use a calibrated oral syringe or a dedicated capsule-filling tray to ensure every unit maintains a consistent volume.
Standardized Filling Protocol
Uniformity depends on homogeneity. Cannabinoid extracts can settle or separate within the oil over time, so ensure the mixture is stirred thoroughly before filling.
- Thermal Prep: If the carrier oil is solid, apply gentle, indirect heat until liquefied. Do not overheat, as excessive temperatures can degrade cannabinoids.
- Volumetric Filling: Use a syringe to dispense the liquid into the body of the capsule. Fill to the brim of the body to reach the target volume.
- Hermetic Sealing: Press the cap firmly onto the body until a distinct tactile click is felt. This indicates the capsule is properly sealed against oxygen.
Calculating Potency and Dose Uniformity
To determine the dosage per capsule, multiply the concentration of the oil by the volume capacity of the chosen shell.
Example: Oil containing 10 mg of THC per ml
- Size 00 (0.7 ml): 7 mg THC per capsule.
- Size 0 (0.5 ml): 5 mg THC per capsule.
For lower concentrations, dilute the concentrate with uninfused carrier oil. A 1:1 dilution of the oil above will yield 3.5 mg and 2.5 mg per capsule, respectively.
Dosage Classification
| Dose Tier | Cannabinoid Content | Potential Use |
|---|---|---|
| Microdose | 1–2.5 mg | Threshold metabolic activity |
| Mild | 2.5–5 mg | Standard therapeutic entry point |
| Moderate | 5–10 mg | Established tolerance |
| Strong | 10–20 mg | Chronic symptom management |
Metabolic onset is a slow process, typically taking 60 to 120 minutes. Advise users to wait at least two hours before considering a second dose to avoid unintended effects.
Stability, Storage, and Shelf Life
Cannabinoids are sensitive to light (photolysis) and oxygen (oxidation). Over time, this exposure may convert THC into CBN, which has a different profile.
- MCT Capsules: These are generally stable at room temperature when stored in an airtight, amber glass container.
- Coconut Oil Capsules: These may require refrigeration to prevent the lipid from melting and compromising the capsule shell.
- Longevity: Properly sealed and stored, these capsules may maintain chemical stability for 6 to 12 months.
Prioritize safety by clearly labeling each container with the infusion date and the exact milligram count per unit.
