Frequently Asked Questions (FAQ)
For beginners, 5–10mg THC per serving is generally safe. Regular users
might prefer 15–25mg. Always start low and wait 1–2 hours before taking more. Our calculator
helps you dial in the right dosage based on your recipe and infused butter.
Yes. Raw cannabis contains THCA, which is not psychoactive. Decarboxylation
turns THCA into THC. Skipping this step will result in weak or inactive edibles.
Absolutely. Coconut oil is high in saturated fat, making it ideal for
cannabinoid absorption. It's also vegan-friendly. Select "Coconut Oil" as your solvent to adjust
density and potency.
Edibles typically take 30–90 minutes, with full effects lasting 4–8 hours.
Start with one serving and wait at least 2 hours before increasing.

Cannabutter Ratio Calculator:
Accurate Dosing Starts
Here
Understanding your cannabutter ratio is the key to creating consistent, effective, and safe
cannabis edibles. Whether you’re infusing butter, oil, or coconut fat, this ratio tells you how much THC (or
CBD) you’re delivering per gram—or per cookie.
What is a Cannabutter Ratio?
The cannabutter ratio is the relationship between the amount of cannabis used and the total fat in your
infusion. This ratio helps you calculate how many milligrams of THC (or CBD) end up in each gram or ounce of
your butter or oil.
Visual guide to cannabutter strength ratios: mild (7g/cup), medium (14g/cup), and strong (28g/cup) potency levels with estimated THC per ounce. Assumes 15% THC cannabis, 88% decarb efficiency, 80% infusion efficiency.
Example:
5 grams (0.18 oz) of cannabis at 20% THC = 1,000mg total THC inside your bud
Decarbed in oven: ~75% efficiency = 750mg active THC
Infused into 1 cup (227g or 8 oz) of butter
= ~3.3mg THC per gram of butter (or ~94mg per oz)
Use Our Calculator
Our edible dosage calculator lets you choose your cannabis strength, infusion method, and
butter amount in both metric and imperial units. No math required.
It also adjusts for infusion loss, decarboxylation efficiency, and lets
you see how strong your final recipe will be—per portion.

Cannabis Oil Ratio Calculator: Infusions Made Simple
Infusing cannabis oil is one of the most versatile ways to create edibles, tinctures, or
topicals. Whether you prefer coconut oil for its binding properties or olive
oil
for flavor and health benefits, knowing your oil-to-cannabis ratio is the key to accurate dosing.
What is a Cannabis Oil Ratio?
The cannabis oil ratio represents how much THC (or CBD) is infused into every milliliter or gram of oil.
This lets you calculate exactly how potent each drop, spoonful, or serving in your recipe will be.
Example:
5 grams of cannabis at 18% THC = ~900mg THC potential
Decarbed: ~75% efficiency → 675mg active THC
Infused into 250ml coconut oil (≈ 1 cup)
= ~2.7mg THC per ml (or ~80mg per fl oz)
Why Choose Oil?
Coconut oil: High fat content = great cannabinoid absorption.
Olive oil: Subtle taste, healthy fats, perfect for savory dishes.
MCT oil: Popular for tinctures & fast-absorbing infusions.

Cannabis Tincture Calculator:
Precision in Every Drop
A cannabis tincture (sometimes called Green Dragon) is an alcohol-based infusion
that
delivers cannabinoids quickly and discreetly. By understanding your tincture ratio, you can
measure exactly how much THC (or CBD) is in every drop or milliliter of liquid.
What is a Cannabis Tincture Ratio?
The tincture ratio is the amount of active cannabinoids dissolved into your alcohol base.
This determines potency per ml, teaspoon, or dropper (≈ 1ml).
Example:
7g cannabis at 20% THC = 1,400mg THC potential
After decarb: ~1,050mg usable THC
Infused into 100ml high-proof alcohol (e.g. 190-proof Everclear)
= ~10.5mg THC per ml (≈ 0.5mg per drop)
Why Choose Tinctures?
Fast absorption: Place under tongue for quicker onset.
Discreet: Easy to dose without cooking.
Long shelf life: Alcohol preserves cannabinoids for years.
Versatile: Can be mixed into drinks, teas, or recipes.
