Cannabis consumers in Nevada have been warned that several batches of products sold in the state were treated with an unapproved pesticide, 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 Nevada Cannabis Compliance Board (CCB) as an approved cannabis pesticide.

On April 22, the CCB issued a public safety bulletin advising consumers to take caution if consuming cannabis products harvested by Circle S Farms LLC. The products – which include “Apple Fritter”, “Double OG Sour”, and “Zummy Bearz” strains – were sold in Nevada dispensaries between March 23 and April 21.

“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.”

The public safety notice is the second the CCB has issued this year in regards to Ethephon contamination. On January 19, the regulator warned that cannabis harvested Clark Natural Medicinal Solutions LLC also contained the unapproved plant growth regulator.
