INTRODUCTION
dosed with requires a conversion factor. The “total potential Δ9THC” factors in the loss
of weight of THCA when converting to Δ9THC. The equation used is as follows:
Total Potential Δ9THC= 0.877*THCA + Δ9THC
This number is an indication of the overall “potency” of the sample.
Total THC: This number is the sum of THCA + Δ9THC and is typically used to indicate
the overall THC cannabinoid content present in a sample. Note this number will always
be greater or equal to the “Total Potential Δ9THC”. We recommend when considering
overall potency to use Total Potential Δ9THC instead of total THC.
CBDA: Cannabidiolic Acid. CBDA is the CBD analog to THCA. It is the acidic from of CBD
that plants produce. Typical non-CBD specific strains will have 0-2% CBDA. CBD
Specific plants typically contain 5-20% CBDA. CBDA is not psychoactive.
CBD: Cannabidiol. CBD is the neutral form of CBDA. Cannabis plants do not create CBD
directly, however this cannabinoid can be formed through the same decarboxylation
process described above.
CBN: Cannabinol. CBN is a breakdown component of Δ9THC. It is mildly psychoactive
and also sedative. Fresh cannabis plants typically show no CBN. Very old plants may
contain 0-5% CBN. CBN can also be generated during extraction or distillation, and
commonly occurs at 0-5% levels in extracted samples. More CBN is typically
undesirable and is an indication of too much heat or exposure to environmental factors.
CBGA: Cannabigerolic Acid. CBGA is a precursor molecule to THCA and CBDA. When a
plant produces cannabinoids, it always produces CBGA first, then an enzymatic process
converts CBGA to THCA and/or CBDA. CBGA can be used as an indicator of harvest
readiness. If >1% CBGA is present in a sample, it typically means the plant can continue
to produce active cannabinoids. A CBGA value of <1% is typically desirable. Plants
commonly contain between 0-4% CBGA.
