Months after Dewayne "Lee" Johnson was soaked from head to toe with a herbicide called Ranger Pro, he noticed lesions on his skin. What he'd developed was called non-Hodgkin lymphoma, a form a cancer that's associated with glyphosate, the chemical the Monsanto Company had long touted as completely safe for humans. In this episode, Colin Ellis speaks with director Jennifer Baichwal about her latest doc "Into the Weeds," which explores Lee's fight for a warning label.
