Calculating THC dose in HOMEMADE Edibles

One of the main questions I get as an edible creator is "How do you know how strong they are". The truth is, I don't. I only give an estimated guess. & Unless you're sending them out to be tested, that's the best you can do. Because making edibles with a safe dose of THC AND achieving a consistent dose PER SERVING can be challenging. However, there is a formula you can use to get you a pretty close approximation. Again, IS THIS FORMULA ACCURATE? ABSOLUTELY NOT! Especially since THC levels vary widely. BUT, This formula will get you as close an estimate as possible, even closer if you know the exact THC percentage in your flower.

Now lets start with the material you are using. According to recent studies, the average percent of THC per gram of flower in the U.S is between 15%-25%. If you're cooking with some low grade, you are gonna want to go with 15%. If you know you got some top shelf then go ahead and use 25%. For today's example, we're gonna go with mids numbers and use 20%.


1 gram of flower = 1,000 milligrams

20% of 1000 milligrams is 200 milligrams

assuming you're using mids, one gram of flower has 200 milligrams of THC.

Lets use our Cannabutter for Beginners recipe for this calculation.

1/2 oz for 1 cup of butter

1/2 oz = 14 grams

14 grams x 200 {milligrams per gram} = 2800 milligrams of THC




There are 16 Tablespoons in a cup so lets divide

2800 by 16

which equals to 175 milligrams of THC per tablespoon.

Now lets say your recipe calls for a 1/2 cup [or 8 tablespoons]

8 [tablespoons] x 175 [milligrams per tablespoon] = 1400 milligrams

Now the final % depends on how many servings your recipe gives.

Ours serves 12

so we divide

1400 [milligrams] by 12 [servings] = 116 milligrams of THC per serving.


You can use this formula any time you make homemade edibles to ensure you are getting a THC dosage that meets your needs.

I hope this helps. If you have any questions, feel free to comment below, email me or dm me on instagram.
