Toxic pesticides found at most illegal California pot farms
SACRAMENTO, Calif. (AP) — Nine of every 10 illegal marijuana farms raided in California this year contained traces of powerful and potentially lethal pesticides that are poisoning wildlife and could endanger water supplies, researchers and federal authorities said Tuesday.
That's a jump from chemicals found at about 75 percent of illegal growing operations discovered on public land last year, and it's six times as high as in 2012.
Federal and state officials launched a summer-long crackdown driven in part by new concern over the increase in the use of the highly toxic pesticide carbofuran.
