What does % THC Max, %CBD Max, and % CBN Max mean on the test results?

Plants produce mostly cannabinoid acids - such as THCA. When heated, THCA loses a carboxyl group and its mass decreases in the process. The %THCmax rpresents the theoretical maximum amount of THC that could be produced if all of the THCA were converted to THC, but one has to account for the loss of 44 mass units from each THCA molecule when it converts.

Thus, the formula is:

%THCmax = [%THCA x 314.5/358.5] + %THC

The process is similar for CBDA/CBD and CBNA/CBN.
