Butter loss can be exactly determined by weighing the completed cannabutter.

Does anyone know how complete the THC transfer to the butterfat is? Is it 100%, or is there some residue left in the original plant material?

Everything else is straight calculation.

The 2nd line values for the 4 oz recipe explains why one of my cannacookies basically wiped my out for a couple of hours.

Here's an Excel spreadsheet for calculating the strength of cannabutter. Does this look fairly accurate? Comments welcome. And anyone who wants a copy of this, please supply an email address and I'll send it. Rating: 5
