SEATTLE- Inside a small lab, technicians at Confidence Analytics convert samples of marijuana into liquid. The green substance is then tested to determine the THC level.
"Growers are interested in a lot of different methods that they could use to improve the quality or increase the potency,” said Nick Mosley, Confidence Analytics co-owner.
Pot producers submit samples, which are then broken down, tested, and inspected for contamination.
"People with respiratory diseases or even allergies to mold, that could be a concern. That's one of the things we look for. Pesticides is another issue that has come up," said Mosley.
So far, the lab has tested over 60 different samples from nearly a dozen pot producers across the state. Mosely said most of the samples met quality standards and will eventually be sold in stores.
Confidence Analytics and Analytical 360 are the only certified marijuana testing labs in the state, according to the Washington State Liquor Control Board.
With stores preparing to open, Mosely said they are testing more marijuana.
The first recreational marijuana stores in Washington are expected to open Tuesday.
