Cannabutter Cooking Calculator

The difficulty of accurately determining cannabutters’ potency is difficult even for professionals, so the following calculations are estimates based on current research and best practices.

What is the THC or CBD Percentage in the Cannabis?

See the label on the packaging for this information.

Typical strains are 10-25% THC, but some strains can have over 25% THC.

CBD varies greatly. Some strains are created and chosen for the higher CBD percentage based on the patient's needs.

If your cannabis is labelled with a percentage of THCA (the non-psychoactive cannabinoid found in raw and live cannabis), rather than THC, enter that percentage here, then see the adjusted calculation for that in the results.

If your original cannabis was labelled with THCA percentage, here is your adjusted amount of THC per serving:

5-10 Mg of THC is the recommended starting dose.

Wait at least 2 hours before having more if you are unsure.

Due to the inefficiency of butter extraction, only an average of 60% of the cannabinoids (such as THC and CBD) are extracted, so this calculation takes that into account (source).

To be sure your cannabutter is as close to possible to this estimated amount of THC or CBD, follow these recommendations:

Decarboxylate (release the full potential of the psychoactive effects using heat) the cannabis.
Use high quality, unsalted, organic butter to avoid additional water and foreign substitutes.
Portion Vertically - If you use only a portion of the cannabutter, do not scoop off of the top. Gravity impacts the way cannabinoids settle.
Mix well - be sure the mixture for your edible using the cannabutter is perfectly uniform throughout.
Cut the final product evenly into the precise number of portions. Use a ruler or scale if needed.
