He spoke for the first time during the trial in San Francisco, detailing his use of Monsanto’s products, his extensive exposure to herbicides, and his belief that the chemicals caused non-Hodgkin lymphoma (NHL), a blood cell cancer. He also described the suffering he endured as skin lesions took over his body.
“I’ve been going through a lot of pain,” said Johnson, a father of three who goes by the name Lee. “It really takes everything out of you … I’m not getting any better.”
His doctors have said he may have just months to live.
Johnson’s lawyers have argued in court that Monsanto has “fought science” over the years and worked to “bully” researchers who have raised concerns about potential health risks of its herbicide product. At the start of the trial, the attorneys presented internal Monsanto emails that they said revealed the corporation’s repeated efforts to ignore expert’s warnings while seeking favorable scientific analyses and helping to “ghostwrite” positive papers.
Thousands have brought similar legal claims across the US, and a federal judge in California ruled this month that hundreds of cancer survivors or those who lost loved ones can also proceed to trial. Johnson’s case has attracted international attention, with the judge allowing his team to present scientific arguments about glyphosate, the world’s most widely used herbicide.
Monsanto has continued to assert that Roundup, which is registered in 130 countries and approved for use on more than 100 crops, is safe and not linked to cancer, despite studies suggesting the contrary. Notably, the World Health Organization’s international agency for research on cancer (IARC) classified glyphosate as “probably carcinogenic to humans” in 2015, a decision that has been central at the trial.
Johnson, 46, took the stand in a crowded courtroom and said he was excited when he first got a job as a groundskeeper and pest manager for the school district in Benicia, a suburb north of San Francisco. Part of the work, which began in 2012, involved spraying herbicide to control weeds on school grounds – sometimes for several hours a day.
Although he wore extensive protective gear while spraying, he was often exposed to the Roundup and Ranger Pro chemicals, both glyphosate-based Monsanto products, due to “drift”, he testified.
“You were getting it on your face everyday,” he said. “It was kind of unavoidable.”

Johnson described two incidents in which he said he was badly exposed to the chemicals due to mishaps and leaking while spraying, including a hose breaking.
“It got on my clothes, got on everything,” he said of one incident, noting that before his cancer, he had “perfect skin”, but after he started spraying and suffered exposures, he got sick and began seeing rashes, lesions and sores all over his body. “I’ve had it bad everywhere.”
He was diagnosed with cancer in 2014.
“It was a very scary, confusing time, and I didn’t know what was happening,” said Johnson, who also recounted his calls to Monsanto seeking information about possible risks, and the lack of responses or cancer warnings from the company.
“It’s so tough when you can’t work, you can’t provide for your family,” added Johnson, who said he would be doing another round of chemotherapy in less than a month.
Araceli Johnson, Dewayne’s wife, also offered emotional testimony in court on Monday, saying she now has two jobs at a local school district and a nursing home, sometimes working 14-hour days.
“It’s very stressful. It’s just too much for me to explain how I really feel,” she said, recounting the cancer diagnosis and aftermath. “My world just shut down. I couldn’t think. I couldn’t clean. I couldn’t do anything.”
His wife recalled the worst moments of chemotherapy when her husband struggled to get out of bed and make it to his uncle’s funeral: “He just starts crying … and saying, ‘I just wanna die.’ And that broke my heart.”
Araceli also talked about their two sons, ages 10 and 13, and said she has had a hard time explaining their father’s cancer. Her message to them, she said, has been: “He’s just very sick … Spend time with him. Get to know your dad.”
In a statement to the Guardian, Monsanto noted studies that have found Roundup is safe, adding: “We have empathy for anyone suffering from cancer, but the scientific evidence clearly shows that glyphosate was not the cause.”
