Updated Testing Regulations
You may start to notice subtle differences on THC testing results on products. Rest assured, you are still receiving the same exceptional products. These adjustments stem from recent updates to testing regulations enacted by the CCC in December 2023.
The modification pertains to the calculation of total THC. You’ll observe that the Total Active Cannabinoids (TAC) in many Flower products now register as lower than THCA. No need for concern; this is entirely accurate.
The bottom line:
The potency and quality of flower remain constant. The revised CCC-mandated testing formula for TAC introduces a variance that lowers TAC to accommodate moisture content.
The following provided by AnalyticsLabs:
The changes put into place by the Cannabis Control Commission (C.C.C.):
What this means is that THCA and CBDA will be mathematically converted to Active forms and added to the active d9-THC and CBD already present.
The equation in the CCC notice was shown as Total THC= d9-THC + (THCA *0.877)
The purpose of this change by the CCC is that THCA is not directly psychoactive, so the conversion represents the total amount of psychoactive THC in flower and concentrate products when consumed by vaporization or combustion.
The second part of the notice was that plant biomass will have its potency calculated including the moisture content, not by dry weight of the biomass that has the moisture subtracted out.
A flower sample potency test is run on a 200 mg sample, and the sample has 10% moisture
200 mg * 0.1 = 20mg of water, you subtract the weight of the water: 200mg – 20mg = 180 mg dry weight
The Third Part of the notice was relative to water activity.
Water activity is a measure of the amount of free water available to support microbial growth on the sample.
Raw plant material will now be tested for water activity
