Cannabis Products in Nevada Are ‘Contaminated’ With Unapproved Pesticide, State Regulator Warns

Cannabis consumers in Nevada have been warned that a certain batch of products sold in the state were treated with an unapproved pesticide, Ethephon.
The products include cannabis flower, shake/trim, uninfused pre-rolls, infused edibles, infused flower, infused pre-rolls, and concentrates.
All products were produced from flower harvested by Clark Natural Medicinal Solutions LLC between July 23, 2021 and January 5, 2023. This information can be found near the top of the label on the affected cannabis products.
There are no known reports of illness from the products at this time.
On January 19, the Nevada Cannabis Compliance Board (CCB) issued a public health and safety notice, advising customers and patients to “avoid or take caution when consuming the cannabis products” possibly contaminated with the pesticide.
“There is no reason to believe the cannabis sales facilities or cannabis testing facilities had any knowledge of the use of this unapproved pesticide,” the CCB wrote in the notice.
“Ethephon is not on the list of pesticides the testing facilities must look for, and their test methods are not set up for detection of Ethephon.”
Ethephon is a plant growth regulator primarily used on cotton crops. It’s registered with the US’s Environmental Protection Agency but not with the CCB as an approved cannabis pesticide.
