On The Cannabist Show: A discussion about cannabis testing labs and their results for THC potency and other cannabinoids in an array of products, from dried flower to edibles and concentrates. Why are there variances in different labs’ results?

EdiPure chief science officer Malcolm Morrison and Nordic Analytical Laboratories lab director Joseph Evans answer questions with Denver Post marijuana editor Ricardo Baca.

The trio discuss the recent Denver recalls on pot products due to pesticides, and the variances allowed in testing procedures under current Colorado law.

EdiPure has been subject to multiple recalls because of banned pesticide residues in its edibles products, and Nordic Analytical Laboratories is a state-certified cannabis testing facility.
