Hello friends

I have a friend who makes space cake edibles

We use 20grams of weed in the butter which will make 20 slices of cake.. Essentially each slice contains and average of 1gram of weed.

The weed contains on average 12%THC

How many mg (milligrams) of THC is in each slice on average?

I believe it is 120mg THC per slice.

Can anyone confirm please?

I'm pretty sure there's a non negligible loss during decarboxylation (baking), either in the form of unconverted THCA or degradation byproducts. 10-15% maybe?

Haven't heard that, I apply the loss factor based on the extraction (absorption?) medium. So you only get 80% of potential cannabinoids with oil, less with butter.

Yes, also true

It depends on what you're using for the extraction. Coconut oil will retain more cannabinoids than butter. I found one source saying up to 80% of that 120mg is retained if you use coconut oil. I believe butter is more like 60%.

So if you're using coconut oil more like 96mg per cake, if butter more like 72mg.
