(Beyond Pesticides, October 10, 2019) Mysterious vaping illnesses across the country could be related to pesticide exposure, among other contaminants in black-market marijuana vaping products. To date, there have been 23 deaths from vaping-related illness, and about 1,100 cases of the illness nationwide. Yesterday, a 17-year-old boy from the Bronx became the youngest person to pass away from the illness. Most patients have reported that they used vape cartridges with THC.
