The Alcohol and Marijuana Control Office issued a plan collecting contaminated cannabis they say originated in Houston, Alaska. 

An investigation earlier this winter by AMCO and the Department of Environmental Conservation’s Pesticide Control program showed cannabis products from the Houston-based cultivator Calm N Collective and retailer Houston Grass Station were treated with an off-market pesticide.

The pesticide, Eagle 20, contains myclobutanil, which is stable at room temperature but releases toxic hydrogen cyanide gas when combusted, according to an advisory notice sent Friday by the Alcohol and Marijuana Control Office. Testing by the MCO, DEC and Department of Health and Social Services showed the products contained high levels of Myclobutanil, a fungicide, and Cyfluthrin, an insecticide — both of which are prohibited for use on cannabis plants in Alaska. 

Now, AMCO is urging all who have products from the distributor to immediately stop using the products bring them into one of the designated collection spots to be properly disposed of by AMCO officials. 

Individuals stores across the state — not affiliated with the contaminated products or the two businesses responsible — have volunteered as collection points:

• Green Life Supply

511 30th Ave.,


 • Alcohol Marijuana Control Office

550 W. Seventh Ave.,

Suite 1600, Anchorage


 • Secret Garden Cannabis

726 E. 15th Ave.


 • Green Elephant

101 Mill St., Suite B


Consumers with any Calm N Collective or Houston Grass Station product are encouraged to email AMCO with the Metrc ID Number or the Batch Number (and the name of the manufacturer) from the label on the original package to: to have an AMCO officer confirm whether the item is a suspect product.
