Leafly Investigation: Is Washington’s Top Cannabis Lab Inflating THC Numbers?
The Cannabis Laboratory Association’s data analysis of 2016 testing results showed a significant discrepancy between the results of potency tests conducted by Peak Analytics and potency tests carried out by the state’s next five largest labs. On average, Peak’s flower samples clocked in at about five percentage points more THC than its competitors.
