Oregon medical marijuana patients are often inhaling cancer-causing pesticides when they buy and use the state's legal medical cannabis concentrates on dispensary shelves. That's the verdict of The Oregonian
, which published a damning expose
on the sorry quality of the state's extracts, despite legal mandates they be lab-tested.
As illustrated in the video below, many cannabis growers are spraying their crops with toxic pesticides to kill bugs and infections that would otherwise cause financial ruin for the farmers. But these plants are later subjected to chemical extraction processes that concentrate both the good and the bad in the plant, raising THC levels and pesticide concentrations.
Just two of ten extracts screened by The Oregonian
were free of pesticides, three should have failed prior lab tests and not made it to store shelves. One marketed as "organic" contained flea and tick killers, and one had ant and cockroach killers at 21 times the legal limit. One extract had traces of seven different pesticide chemical compounds.
Oregon requires pesticide testing of flowers, but not concentrates, and there is other legal loopholes allowing dangerous products to hit the market.
Without federal guidance for pesticide use, states are making their own lists of banned chemicals and acceptable toxin levels. Under Washington guidelines, nine of ten Oregon extracts would have failed screening. Oregon medical cannabis patients are assuming an unwarranted level of safety and cleanliness, The Oregonian
You can bet California's totally unregulated system is even dirtier. Pending Assembly Bill 266
would mandate testing for the first time in California.
