The DDT you see in the table below, all 0.816 mg/kg of it, is fresh, potent, and highly reactive, not just trace soil or water residuals from 50 years ago. It was sprayed directly, heavily and very recently on the tobacco used to make Swisher Sweets. There is a total worldwide ban on the use of DDT on crops, by the way. That’s another story, which I document in my book “Smoke No Evil“.
