In late April, Leafly News reporter Tobias Coughlin-Bogue reported that complaints had been submitted to the Washington State Liquor and Cannabis Board (WSLCB) by a group of industry members that accused Peak Analytics, one of the state’s largest cannabis testing labs, of “consistent and large-scale inaccuracies.” According to the Cannabis Laboratory Association, a group of state-licensed testing labs that was formed to promote industry standards, data analysis of 2016 testing results showed significant differences between the results of potency tests conducted by Peak and potency tests carried out by some of the other large testing labs in the state.

At the time, a Peak representative said the lab met “all state, local, and WSLCB mandated regulations” and that its testing methods were scientifically valid.
