Marijuana products that were pulled from store shelves in early November have tested positive for pesticides that could pose health risks.

The marijuana was grown at Houston cultivator Calm N Collective and sold at their retail store, Houston Grass Station, as well as other retail stores around the state.

Glen Klinkhart, the interim director of the state’s Alcohol and Marijuana Control Office, said the state tested product samples in four areas including marijuana and marijuana concentrates. They found high levels of myclobutanil, a fungicide, and cyfluthrin, an insecticide, in all four.

“If the test had come back and they were zero, and nothing was wrong, then we would learn from it and move on,” said Klinkhart. “In this case, these tests came back positive with levels that were much higher than should ever be with these particular pesticides and fungicides.”

Dr. Robert Hendrickson is the associate medical director for the Oregon Poison Control Center, which also serves Alaska. He said he would not consider the pesticides a danger for someone who has ingested a small amount.

His bigger concern is for people who have used contaminated smoking or vaping products repeatedly over time and said that anyone who has concerns about ill effects should see a doctor.

People who have purchased products grown or manufactured at Calm N Collective should not use them, but return them.

The products can be dropped off at the Alcohol Marijuana Control Office in Anchorage or to one of three retail stores that have agreed to accept products so they can be destroyed. Those stores include Secret Garden Cannabis in Anchorage, Green Leaf Supply in Fairbanks and Green Elephant in Juneau.

The investigation as to why and how the unapproved pesticides were used is ongoing, according to Klinkhart. He said the owners of Calm N Collective will have an opportunity to present their case to the Marijuana Control Board, which has the authority to fine them or even pull their license.

Unlike Washington or Oregon, Alaska does not regularly test marijuana products for pesticides. Going forward, Klinkhart said the state will consider if there are things they can do better to ensure products are safe.
