Yes, you can fill cannabis oil capsules at home. The process is short: blend a cannabis infusion or distillate into a carrier oil, then dose that blend into empty capsules with a syringe. The part that matters is consistency. A dispensary capsule lists milligrams of THC or CBD on the label. A homemade batch is only as accurate as your starting oil and your math, so measure before you fill.

What you need
- Empty gelatin or vegetarian capsules, most often size 0 or 00
- Cannabis infusion made with coconut oil, MCT oil, or olive oil, or a measured distillate
- Plain carrier oil if you plan to dilute a strong infusion
- Blunt tip syringe or pipette
- Capsule filling tray or holder
- Kitchen scale that reads to 0.01 g, nitrile gloves, and blank labels
Steps
- Write down the total milligrams of THC or CBD in your oil, taken from your infusion notes or the distillate test label.
- Pick a target dose per capsule and divide the total potency by that number to see how many capsules the batch will make.
- Warm the oil to 90 to 100 degrees F so it flows, and stir it so the cannabinoids spread through the carrier.
- Draw the oil into the syringe, then wipe the outside of the tip with a clean cloth.
- Fill each capsule body to just below the rim, using the fill volume chart that came with your tray.
- Press the cap onto the filled body until it seats, then stand the capsule upright in the tray.
- Let the capsules cure in a sealed container for 12 to 24 hours so the shell absorbs oil and the seam holds.
- Weigh three finished capsules and compare the weights to catch any that leaked or came up short.
- Tag the batch with the date, oil type, milligrams per capsule, and capsule count.
- Take one capsule and wait two hours before deciding on another, since oil capsules peak later than inhaled cannabis.
Storage and safety
Keep filled capsules in an airtight jar in a cool, dark, dry place, away from heat and direct light. Gelatin shells pull moisture from a refrigerator, so a cabinet beats the fridge for short term storage. For longer storage, freeze the jar with a desiccant packet. Treat the batch like any other edible: keep the jar locked, write the potency in plain words on the label, and remember that poison centers log thousands of edible cannabis exposure calls each year, many of them involving children.

How dispensary capsules compare
When you buy capsules at a cannabis store, you get a per-capsule potency number from a lab test, a batch code, and a package date. Ask the budtender for the milligrams of THC and CBD per capsule, whether the oil is distillate or full spectrum, and a suggested starting amount for someone new. Homemade capsules seldom match that accuracy. If you want predictable results, store-bought is the shorter path. If you already infuse your own oil, the steps above let you fill your own.

Legal check
Home production rules differ by state. Some states cap how much concentrate you may make or possess, and some ban solvent based extraction outside licensed facilities. Check your state cannabis authority before you start, and do not carry homemade capsules across state lines.
