How to use this tincture dose calculator
Enter your decarbed cannabis weight in grams, THC and CBD percentages, and total alcohol volume. The calculator applies decarboxylation and infusion efficiency to estimate active cannabinoids dissolved in your tincture.
- Beginners: start with 2–5 mg THC per dose (about 0.2–0.5 ml if your tincture is ~10 mg/ml).
- Standard dose: 5–10 mg THC — wait 30–60 minutes before taking more.
- Dropper math: a standard 1 ml dropper holds ~20 drops; divide mg/ml by 20 for mg per drop.
