The state has issued its second "health alert" for marijuana contaminated with pesticides or pesticide ingredients, in this case three strains of marijuana flowers sold from dispensaries in Salem, Eugene and North Bend.
The Oregon Health Authority is advising anyone who bought the strains to either return them to the dispensaries or dispose of them.
It's not clear how the tainted marijuana ended up on store shelves after apparently failing lab tests. Health authority officials are investigating why that happened. Producers are supposed to destroy the strains that fail pesticide tests.
The state is withholding the names of the growers, saying it's confidential information.
