Cannabis licensees around the state have been cautioned to pull and quarantine all packages from cannabis cultivator Calm N Collective due to possible pesticide contamination.

The pesticide in question, Eagle 20, contains myclobutanil, which is stable at room temperature but releases toxic hydrogen cyanide gas when combusted, according to an advisory notice sent out Friday by the Alcohol and Marijuana Control Office.

AMCO and the Department of Environmental Conservation Pesticide Control Program are investigating Calm N Collective because the state received credible information that the Houston, Alaska-based cultivator used myclobutanil on cannabis grown in their facility, the advisory states.

Myclobutanil is a fungicide that has been banned for use on recreational and medical marijuana in Washington, Oregon, Colorado and Canada. Hydrogen cyanide gas was used briefly in World War I and more extensively by the Germans in concentration camps in World War II.

A hydrogen cyanide concentration of 100 to 200 ppm in the air will kill a human within 10 to 60 minutes, according to the International Cyanide Management Code.

Affected packages can be identified on the Marijuana Enforcement Tracking Reporting & Compliance website. Alcohol & Marijuana Control Office will notify all licensees of updates as they become available, according to the advisory notice.

Questions can be sent to amco.enforcement@alaska.gov.
