Fact check
“The methylene chloride was detected by a third‑party lab, Kaycha Labs, in Denver.”
Reasoning
The claim is directly supported by two excerpts from a ProPublica article that describe Kaycha Labs as the third‑party lab that identified the toxic solvent methylene chloride in the recalled marijuana vape products.
On confidence: Multiple primary sources from ProPublica explicitly state that Kaycha Labs, a third‑party cannabis testing facility in Denver, detected methylene chloride in the products.
Important context
The detection was part of a voluntary recall by the manufacturer after state testing protocols were delayed; the lab’s role was to test for contaminants.
