KCET, a local California TV station, reported that “Cannabis products from joints to vape cartridges purchased from 11 illegal marijuana dispensaries and delivery services across the Los Angeles area contained varying amounts of pesticides so deadly some have been banned around the world.”
The investigation, reported in the Dec. 17 program, tested 36 products, finding evidence of the pesticides Fipronil, Carbofuran, Chlorfenapyr, Dichlorvos, and Paclobutrazol, which the California Department of Pesticide Regulation lists as pesticides that should never be used in cannabis farming.
“More than 3,000 times the legal amount of the fungicide Myclobutanil allowed was found on a pre-rolled joint handed out free to customers at one business. When heated, the chemical can produce toxic fumes including carbon monoxide, carbon dioxide, hydrogen chloride and hydrogen cyanide, according to the National Oceanic and Atmospheric Administration website,” the station reported
Carbofuran, a pesticide banned in Canada and the European Union, and prohibited from use with food crops in the United States, was found in one sample. A vape cartridge purchased from another business failed for the element mercury, which can cause serious damage to the body.
