Denver health officials on Tuesday started inspecting and quarantining hundreds of cannabis products because their labels listed pesticides not approved by the state for use on marijuana.
The city's move came about six months after officials had quarantined 100,000 plants at 11 grow facilities due to concerns about pesticide use, report David Migoya and Ricardo Baca at The Denver Post.
No safety standards exist for pesticide use on marijuana. Since cannabis is illegal under federal law, the U.S. Environmental Protection Agency, which regulates pesticides, has never established any limits.
However, since marijuana is legal in Colorado, the state Department of Agriculture there has created a listed of allowed pesticides, as has its counterpart in Washington state, where recreational pot is also legal.
The quarantines were put on Mountain High Suckers and MMJ America after Denver's Department of Environmental Health late Monday warned businesses that products with labels reflecting the use of banned pesticides should be removed from shelves and destroyed, or returned to the manufacturers.
Colorado law requires all cannabis product labels to list pesticides, contaminants, fungicides and herbicides that were used, from germination to packaging.
